The flexibility ontology module (ic-flex) is by design tightly integrated with SAREF, SAREF4ENER and the following InterConnect modules: power limit (ic-pwlm), incentive table (ic-inc), S2 (ic-s2), data-point (ic-data) and forecast (ic-fc) The main concept of the ic-flex module is the s4ener:FlexOffer, which allows to represent a flexibility offer (or schedule) as a combination of multiple time-series, data-points and forecasts. It also allows to specify a creation time (s4ener:hasCreationTime), validity period (s4ener:hasEffectivePeriod) and provenance (s4ener:producedBy) for the offer, on top of the creation time, validity period and provenance already specified for the time-series and data-points included in the offer. The additional key aspect captured in the ic-flex module is that a flex offer can also include various categories of flexibility, which are modelled as subclasses of the s4ener:FlexibilityProfile class, as follows: - Power Profile flexibilty is modelled as s4ener:PowerProfile based on the EEBUS spec - Tariff based flexibility (s4ener:TariffBased) is implemented using the incentive table (ic-inc) ontology based on the EEBUS spec (note that tariif-based felxibility does note exist in S2) - Power limit flexibility (ic-pwlm:PowerLimit) is implemented using thepower limit (ic-pwlm) ontology based on the EEBUS spec (and compliant also with S2) - Power Envelope flexibility (s4ener:PowerEnvelope) is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with EEBUS) - Demand driven flexibility (s4ener:DemandDriven) flexibility (s4ener:PowerEnvelope) is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with EEBUS) - Operation mode flexibility (s4ener:OperationMode) is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with S2) - Fill rate based flexibility (s4ener:FillRateBased is implemented using theS2 (ic-s2) that follows the S2 specification (and compliant also with S2) @en
