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: 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.

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.
