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.
