Abstract
Several approaches have been proposed to enhance the potential of distributed generation (DG). Some of the most prominent solutions include the aggregation of DG units and other players, culminating in the concept of and Smart Grid (SG). In this context, several simulation tools arose to study and test the new market mechanisms. However, all of these simulators are closed and centred in their object of study, neglecting the potential advantages of interoperating with other systems from the same domain. This work proposes the use of ontologies for systems interoperability in the power and energy systems domain. The ontologies have been developed and implemented in MASCEM and MASGriP - multi-agent simulators of electricity markets, and SG operation and management,respectively; thus enabling joint electricity market and SG simulations.
Highlights
The deregulation of electricity markets (EM), the high penetration of distributed generation (DG) units as well as other distributed energy resources, require more intelligent operation methods
MASCEM interacts with heterogeneous multi-agent systems (MAS) developed within GECAD research group
There is the need to interconnect them in order to enable the study of broader and complex scenarios
Summary
The deregulation of electricity markets (EM), the high penetration of distributed generation (DG) units as well as other distributed energy resources, require more intelligent operation methods. The MBL ontology imports EMO, extending some of EMO’s concepts – namely Bid, Market, MarketType and Session – and including the ComplexConditions class and subclasses. The ComplexConditions object is included as a new concept together with its particular subclasses, namely: CompleteAcceptanceInEachHourInTheMatchingPeriodOfTheFirstBlockOfTheBid, CompleteAcceptanceInTheMatchingProcessOfTheFirstBlockOfTheBid, Indivisibility, LoadGradient, MaximumMatchedPower, MaximumPayment, MinimumIncome, MinimumNumberOfConsecutiveHoursOfCompleteAcceptance OfTheFirstBlockOfTheBid and ScheduledStop, representing the different types of complex conditions available in the Iberian market. BuyBid and SaleBid are types of bids inferred depending on their transactionType data property, while an InvalidRegularBid represents a Bid with more than 25 fractions (EMO:Offer) This ontology is used both by players and by the market operator.
