Absolute physical limits (for example generator or +line capacities) are *not* modelled as commitments — those are enforced as +Pyomo constraints. + +Key properties +-------------- + +Each Commitment has the following important attributes (high level): + +- ``name`` — a logical string identifier (e.g. ``"energy"``, ``"production peak"``). +- ``device`` — optional: restricts the commitment to a single device; otherwise + it is an EMS/site-level commitment. +- ``index`` — the DatetimeIndex (time grid) on which the series are defined. +- ``quantity`` — the baseline Series (per slot or per group). +- ``upwards_deviation_price`` — Series defining marginal cost/reward for upward deviations. +- ``downwards_deviation_price`` — Series defining marginal cost/reward for downward deviations. +- ``_type`` — grouping indicator: ``'each'`` or ``'any'`` (see Grouping below). + +Sign convention (flows vs stocks) +-------------------------------- + +- **Flow commitments** (e.g. power/energy flows): + + - A *positive* baseline quantity denotes **consumption**. + + - Actual > baseline → *upwards* deviation (more consumption). + - Actual < baseline → *downwards* deviation (less consumption). + - A *negative* baseline quantity denotes **production** (feed-in). + + - Actual less negative (i.e. closer to zero) → *upwards* deviation (less production). + - Actual more negative → *downwards* deviation (more production). + +- **Stock commitments** (e.g. state of charge for storage): + + - ``quantity`` is the target stock level; deviations above/below that target + are priced via the upwards/downwards price series. + +Soft vs hard semantics +---------------------- + +Commitments in FlexMeasures are **soft** by design: they represent economic +penalties or rewards that the optimizer considers when building schedules. +Hard operational constraints (such as physical power limits or strict device +interlocks) are expressed separately as Pyomo constraints in the scheduling +model. If a “hard” behaviour is required from a commitment, assign very large +penalty prices, but prefer modelling non-negotiable limits as Pyomo constraints. + +Converting flex-context fields into commitments +----------------------------------------------- + +Users may supply preferences and price fields in the ``flex-context``. The +scheduler translates the relevant fields into one or more `Commitment` objects +before calling the optimizer. + +Typical translations include: + +- tariffs (``consumption-price``, ``production-price``) → an ``"energy"`` FlowCommitment with zero baseline so net consumption/production is priced; +- peak/excess limits (``site-peak-production``, ``site-peak-production-price``, etc.) → dedicated peak FlowCommitment(s); +- storage-related fields (``soc-minima``, ``soc-minima-breach-price``, etc.) → StockCommitment(s). + +A short example +--------------- + +Below is a compact example showing how the scheduler conceptually creates an +``"energy"`` flow commitment from a (per-slot) tariff: + +.. code-block:: python + + from pandas import Series, date_range + from flexmeasures.data.models.planning import FlowCommitment + + index = date_range(start="2025-01-01 00:00", periods=24, freq="H") + # zero baseline → the asset may consume or produce; deviations are priced. + baseline = Series(0.0, index=index) + + # consumption and production tariffs (per kWh) + consumption_price = Series(0.20, index=index) # 0.20 EUR/kWh for consumption + production_price = Series(-0.05, index=index) # -0.05 EUR/kWh reward for production + + energy_commitment = FlowCommitment( + name="energy", + index=index, + quantity=baseline, + upwards_deviation_price=consumption_price, + downwards_deviation_price=production_price, + _type="each" + ) + +The scheduler sets up such commitments (site-level and device-level) and, together with any prior commitments, hands them to the linear optimizer. + +Examples (commitments commonly derived from flex-context) +-------------------------------------------------------- + +The examples below map the most common `flex-context` semantics to the +commitments the scheduler constructs. + +1. **Energy (tariff)** + + - *Fields used*: ``consumption-price``, ``production-price``. + - *Commitment*: Flow commitment named ``"energy"`` with zero baseline and + the two price series as upwards/downwards deviation prices. + +2. **Peak consumption** + + - *Fields used*: ``site-peak-consumption`` (baseline) and ``site-peak-consumption-price`` (upwards-deviation price); the downwards price is set to ``0``. + - *Commitment*: Flow commitment named ``"consumption peak"``; positive baseline + values denote the prior consumption peak associated with sunk costs, and the upwards price penalises going beyond that baseline. + +3. **Peak production / peak feed-in** + + - *Fields used*: ``site-peak-production`` (baseline) and ``site-peak-production-price`` (downwards-deviation price); the upwards price is set to ``0``. + - *Commitment*: Flow commitment named ``"production peak"``; negative baseline + values denote the prior production peak associated with sunk costs, and the downwards price penalises going beyond that baseline. + +4. **Consumption capacity** + + - *Fields used*: ``site-consumption-capacity`` (baseline), and ``site-consumption-breach-price`` (upwards-deviation price); the downwards price is set to ``0``. + - *Commitment*: Flow commitment named ``"consumption breach"``; positive baseline + values denote the allowed consumption limit and the upwards price penalises going + beyond that limit. + +5. **Production capacity** + + - *Fields used*: ``site-production-capacity`` (baseline) and ``site-production-breach-price`` (downwards-deviation price); the upwards price is set to ``0``. + - *Commitment*: Flow commitment named ``"production breach"``; negative baseline + values denote the allowed production limit and the downwards price penalises going + beyond that limit. + +6. **SOC minima / maxima (storage preferences)** + + - *Fields used*: ``soc-minima``, ``soc-minima-breach-price``, ``soc-maxima`` and ``soc-maxima-breach-price``. + - *Commitment*: StockCommitment(s) that price deviations below minima or + above maxima.

Claessen * test: add comprehensive coverage for aggregate-consumption/production flex-context fields - Add test_asset_trigger_and_get_aggregate_schedule to verify aggregate sensors get populated (currently xfail as StorageScheduler doesn't yet populate them) - Add test_asset_trigger_with_multi_commodity_flex_context to verify aggregate sensors work with multi-commodity flex-context format (list of commodity dicts) - Document that aggregate sensor population is missing logic in StorageScheduler - Both tests verify the infrastructure and schema support works correctly * fix: compute per-commodity aggregate power flows for aggregate-consumption and aggregate-production sensors Signed-off-by: F.N. Claessen * Include per-commodity inflexible devices in aggregate schedules _compute_commodity_aggregate_schedules only added the top-level inflexible devices to the electricity commodity, so a commodity's own inflexible demand (e.g. a heat load) was excluded from its aggregate-consumption schedule. The aggregate then reflected only that commodity's flexible devices. Mirror the device enumeration used in _prepare so each commodity context's inflexible-device-sensors are appended to that commodity at the matching ems_schedule indices. * test: update aggregate sensor tests to verify implementation - Remove xfail markers from both tests now that StorageScheduler populates aggregate sensors - Update test docstrings to reflect actual functionality - Tests now verify that aggregate-consumption and aggregate-production sensors receive data - First test covers single aggregate pair with dual devices - Second test covers aggregates with multiple devices scheduling together * feat: test commodities referenced in only the flex-model or only the flex-context Signed-off-by: F.N. Claessen * feat: test logs should explain why response was unexpected Signed-off-by: F.N. Claessen * style: black Signed-off-by: F.N. Claessen * feat: AssetTriggerSchema accepts list-like flex-contexts Signed-off-by: F.N. Claessen * fix: skip aggregate computation for unused commodities When a multi-commodity flex_context includes a commodity (e.g., heat) but no devices exist for that commodity, the sum() of an empty list returns integer 0 instead of a pandas Series. This caused AttributeError when calling .round() on the result later in compute(). Fixed by checking if any devices contribute to the commodity before attempting to aggregate. If no devices exist for a commodity, skip creating an aggregate schedule for it. Signed-off-by: F.N. Claessen --------- Signed-off-by: F.N.

The scheduler links the energy balance of all feeds to that single state of charge, rather than tracking a separate stock per device. +- **The shared-storage entry has no power ``sensor``.** It only carries the storage-level fields (``soc-at-start``, ``soc-min``, ``soc-max``, ``soc-usage``), which describe the buffer as a whole and must therefore not be repeated per feeder. +- **Per-device efficiencies live in the device entries.** The heat pump's ``charging-efficiency`` of ``300%`` reflects its COP of 3 (1 kWh in yields 3 kWh of heat), while the resistive heater converts electricity to heat one-to-one at ``100%``. ``production-capacity`` of ``0 kW`` on both feeders means neither can extract heat back out of the buffer — they only ever charge it. +- **``soc-usage`` models the continuous heat demand.** Unlike a one-off ``soc-targets`` entry, it drains the buffer throughout the horizon, so the scheduler must keep feeding it rather than just reach a target once. Here it steps from a 4 kW baseline up to 18 kW for a two-hour morning peak. +- **The narrow gap between ``soc-min`` and ``soc-max``** leaves the buffer only 2 kWh of slack, so it cannot simply pre-heat well ahead of the morning peak. It also means that once the heat pump's power capacity is exhausted during the peak, the buffer has almost nowhere else to draw from — which is what forces the resistive heater into action. + +.. note:: The ``state-of-charge`` sensor should have an instantaneous resolution (``PT0M``), since it records a stock value at a point in time rather than a quantity accumulated over an interval. See the ``state-of-charge`` field in :ref:`flex_models_and_schedulers`. + +For the costs, we use a flat tariff in this example, identical at every hour, so price differences over time play no role in the schedule — only the buffer's physical constraints (capacity and ongoing usage) determine *when* each feeder runs. +The flat tariff still lets the scheduler tell the feeders apart: since the heat pump needs less electricity for the same amount of heat, it is the cheaper choice whenever either feeder could do the job. + +.. code-block:: json + + { + "flex-context": { + "consumption-price": "100 EUR/MWh", + "production-price": "100 EUR/MWh" + } + } + + +Triggering the schedule +======================= + +We schedule on the **heat buffer asset**, so that FlexMeasures considers both feeders together as feeds into the buffer's shared stock. + +.. tabs:: + + .. tab:: CLI + + .. code-block:: bash + + $ flexmeasures add schedule \ + --asset 1 \ + --start 2024-01-01T00:00+01:00 \ + --duration PT24H \ + --flex-model flex-model-multi-feed.json \ + --flex-context flex-context-flat-price.json + New schedule is stored. + + .. tab:: API + + Example call: `[POST] http://localhost:5000/api/v3_0/assets/1/schedules/trigger <../api/v3_0.html#post--api-v3_0-assets-id-schedules-trigger>`_: + + .. code-block:: json + + { + "start": "2024-01-01T00:00:00+01:00", + "duration": "PT24H", + "flex-model": [ + { + "sensor": 1, + "state-of-charge": {"sensor": 3}, + "power-capacity": "5 kW", + "production-capacity": "0 kW", + "charging-efficiency": "300%" + }, + { + "sensor": 2, + "state-of-charge": {"sensor": 3}, + "power-capacity": "15 kW", + "production-capacity": "0 kW", + "charging-efficiency": "100%" + }, + { + "state-of-charge": {"sensor": 3}, + "soc-at-start": 20.0, + "soc-min": 20.0, + "soc-max": 22.0, + "soc-usage": [ + {"start": "2024-01-01T00:00:00+01:00", "duration": "PT7H", "value": "4 kW"}, + {"start": "2024-01-01T07:00:00+01:00", "duration": "PT2H", "value": "18 kW"}, + {"start": "2024-01-01T09:00:00+01:00", "duration": "PT15H", "value": "4 kW"} + ] + } + ], + "flex-context": { + "consumption-price": "100 EUR/MWh", + "production-price": "100 EUR/MWh" + } + } + + .. tab:: FlexMeasures Client + + Using the `FlexMeasures Client `_: + + .. code-block:: python + + schedule = await client.trigger_and_get_schedule( + asset_id=1, # the heat buffer asset + start="2024-01-01T00:00:00+01:00", + duration="PT24H", + flex_model=[ + { + "sensor": 1, # heat pump power sensor + "state-of-charge": {"sensor": 3}, + "power-capacity": "5 kW", + "production-capacity": "0 kW", + "charging-efficiency": "300%", + }, + { + "sensor": 2, # resistive heater power sensor + "state-of-charge": {"sensor": 3}, + "power-capacity": "15 kW", + "production-capacity": "0 kW", + "charging-efficiency": "100%", + }, + { + "state-of-charge": {"sensor": 3}, # shared stock + "soc-at-start": 20.0, + "soc-min": 20.0, + "soc-max": 22.0, + "soc-usage": [ + {"start": "2024-01-01T00:00:00+01:00", "duration": "PT7H", "value": "4 kW"}, + {"start": "2024-01-01T07:00:00+01:00", "duration": "PT2H", "value": "18 kW"}, + {"start": "2024-01-01T09:00:00+01:00", "duration": "PT15H", "value": "4 kW"}, + ], + }, + ], + flex_context={ + "consumption-price": "100 EUR/MWh", + "production-price": "100 EUR/MWh", + }, + ) + + +The scheduler returns one schedule per feeder (stored on sensors ``1`` and ``2``), and the resulting state of charge (stored on the shared ``state-of-charge`` sensor ``3``). +Note that the costs are *not* duplicated per device: because the feeders feed one shared storage, FlexMeasures computes a single energy balance for the buffer. + + +What to expect +============== + +With a flat tariff, the schedule is driven by the buffer's physical constraints (its narrow ``soc-min``/``soc-max`` band and the ongoing ``soc-usage``) *together with* each feeder's efficiency. +The scheduler specialises each feeder for the situation it is needed in: + +- **The heat pump** covers the baseline heat demand (4 kW) throughout most of the day, drawing just over 1 kW of electricity thanks to its COP of 3. It is cheaper than the resistive heater for the same amount of heat, so the optimiser always prefers it when its power capacity allows. +- **The resistive heater** stays idle until the two-hour morning peak (18 kW), when demand exceeds what the heat pump can supply even at its own power capacity (15 kW of heat). It switches on for the first part of the peak, covering the shortfall the heat pump cannot. Towards the end of the peak, the optimiser instead lets the buffer's thin 2 kWh reserve (between ``soc-min`` and ``soc-max``) drain the rest of the way — that stored heat is "free" to use, so it is spent before calling on the resistive heater any longer than necessary. + +So, even though both feeders *could* run at any time, the optimiser only calls on the resistive heater when neither the heat pump's power capacity nor the buffer's thin margin is enough to keep up with demand. The rest of the time, the cheaper, more efficient heat pump handles everything on its own. + +.. image:: https://github.com/FlexMeasures/screenshots/raw/main/tut/multi-feed-heat-buffer.png + :align: center +| + +Reading the chart top to bottom: + +- **Feeders** (top panel) shows the power schedule of both feeds together. The heat pump runs at a modest, steady power level for most of the horizon to match the baseline demand, then ramps up to its own power capacity during the morning peak. The resistive heater stays idle until the peak, switches on alongside the heat pump to cover the shortfall, then drops back to idle again before the peak ends, once it's cheaper to draw on the buffer's remaining reserve instead. +- **Shared storage** (bottom panel) shows the *single* ``state-of-charge`` sensor that both feeders feed. It sits at the 22 kWh ``soc-max`` for most of the day, dips to the 20 kWh ``soc-min`` by the end of the morning peak — as its thin 2 kWh reserve is spent covering the tail end of the shortfall — and recovers immediately afterwards. This one curve is the combined effect of both feeds and the ongoing usage, which is exactly what "shared stock" means. + +.. note:: This same pattern generalises beyond two feeders and beyond heat buffers. Any number of devices can feed a shared storage — as long as each device entry references the same ``state-of-charge`` sensor and a single entry carries the shared-stock constraints. + +We hope this demonstration helped to illustrate how FlexMeasures schedules multiple feeds into a shared storage. +For modelling a single storage device in more depth, head back to :ref:`tut_v2g`. +To see how devices on *different* commodities (e.g. electricity and gas) are scheduled together, continue to :ref:`tut_multi_commodity`. diff --git a/flexmeasures/api/common/schemas/scheduling.py b/flexmeasures/api/common/schemas/scheduling.py index f33c5ee555..92c02329e5 100644 --- a/flexmeasures/api/common/schemas/scheduling.py +++ b/flexmeasures/api/common/schemas/scheduling.py @@ -1,6 +1,6 @@ from flexmeasures.api.common.schemas.utils import make_openapi_compatible from flexmeasures.data.schemas.scheduling.storage import StorageFlexModelSchema -from flexmeasures.data.schemas.scheduling import FlexContextSchema +from flexmeasures.data.schemas.scheduling import CommodityFlexContextSchema from flexmeasures.data.schemas.sensors import SensorIdField @@ -18,4 +18,4 @@ } ], ) -flex_context_schema_openAPI = make_openapi_compatible(FlexContextSchema) +flex_context_schema_openAPI = make_openapi_compatible(CommodityFlexContextSchema) diff --git a/flexmeasures/api/common/schemas/utils.py b/flexmeasures/api/common/schemas/utils.py index f457d2bed2..3c7174cee2 100644 --- a/flexmeasures/api/common/schemas/utils.py +++ b/flexmeasures/api/common/schemas/utils.py @@ -32,7 +32,11 @@ def make_openapi_compatible( # noqa: C901 sensor_only_validators.append(validator[-1]) new_fields = {} - tobeadded_fields = schema_cls._declared_fields + try: + # in case `schema_cls.__init__` reordered the fields, preserve their order + tobeadded_fields = schema_cls().fields + except TypeError: + tobeadded_fields = schema_cls._declared_fields if include: for item in include: tobeadded_fields.update(item) diff --git a/flexmeasures/api/v3_0/assets.py b/flexmeasures/api/v3_0/assets.py index 409abce35a..5e645b2216 100644 --- a/flexmeasures/api/v3_0/assets.py +++ b/flexmeasures/api/v3_0/assets.py @@ -96,22 +96,24 @@ def __init__(self, *args, **kwargs): kwargs["exclude"] = ["asset"] super().__init__(*args, **kwargs) - flex_context = fields.Nested( - flex_context_schema_openAPI, - required=True, + flex_context = fields.List( + fields.Nested( + flex_context_schema_openAPI(), + ), + load_default=[], data_key="flex-context", metadata=dict( - description="The flex-context is validated according to the scheduler's `FlexContextSchema`.", + description="Flex-context per commodity.

Claessen" Date: Wed, 8 Jul 2026 08:30:46 +0200 Subject: [PATCH 233/252] Add smarter defaults for commodity contexts A commodities-list entry that omits some or all grid-connection fields (consumption-price, production-price, site-consumption- capacity, site-production-capacity, site-power-capacity) previously either failed (a missing consumption-price crashes the scheduler) or left ambiguous, error-prone combinations to fill in by hand. Add CommodityFlexContextSchema.fill_grid_connection_defaults, a post-load step that derives sensible defaults from which of those five fields were explicitly given: - none given: no grid connection (both site capacities default to 0, as soft constraints; site-power-capacity stays unlimited) - only a price given: assume a grid connection in that direction (unlimited capacity there), 0 capacity in the other direction - only a capacity given: 0 price in that direction, and the other direction defaults to a 0 capacity (and price) - only site-power-capacity given: a hard constraint at that capacity for both directions, with 0 prices Combinations of explicitly given fields apply the same rules per direction independently. A 0 capacity filled in by this method is enforced as a soft constraint (a default breach price is filled in too), not a hard, potentially infeasible, one; explicit hard constraints (e.g. via site-power-capacity alone) get no breach price.

In short: a fully bare commodity context (e.g. just ``{"commodity": "gas"}``) is treated as having no grid connection at all (both site capacities default to 0, as soft constraints); giving only a price for one direction assumes a grid connection in that direction (with an unlimited capacity, unless a capacity is also given) and a 0 capacity in the other direction; giving only a capacity for one direction implies a 0 price for that direction (and a 0 capacity/price for the other direction); and giving only ``site-power-capacity`` sets a hard constraint at that capacity for both directions, with 0 prices. See ``CommodityFlexContextSchema.fill_grid_connection_defaults`` for the full precedence rules. **Behaviour change:** previously, a partially-specified commodity context left unmentioned capacities unlimited and would hard-error if no resolvable ``consumption-price`` could be determined; now, unmentioned capacities/prices are filled in per the rules above (typically a 0-capacity soft constraint plus a 0 price), so such contexts load successfully and no longer raise that error. A commodity context with no user-given price fields at all also no longer trips a spurious cross-currency error against a differently-currencied portfolio; its 0-price/breach-price fills instead inherit the portfolio's real currency where determinable.

Claessen" Date: Fri, 10 Jul 2026 18:52:53 +0200 Subject: [PATCH 244/252] feat: balance internal commodity nodes with first-class balance groups Adds a balance_groups argument to device_scheduler: each group lists the devices of an internal commodity node (e.g. a heat or steam network without a grid connection) whose stock-side flows must sum to zero at every time step. This replaces the reference-device min=max=0 stock-group workaround used by the factory scenario, which is now tested in both modes. The StorageScheduler derives balance groups from the flex-config: a non-electricity commodity without energy prices becomes an internal node (previously this raised 'Missing consumption price'). Together with coupling groups (one flex-model entry per converter port), this makes the factory scenario (CHP + gas boiler + e-heater meeting a fixed steam demand) schedulable end-to-end through StorageScheduler.compute().
