Interface Accounting

  • All Known Implementing Classes:
    AccountingService
    public interface Accounting
    Common interface for the PowerTAC accounting service. The accouting service module is responsible for bookeeping, with respect to cash (broker bank accounts) and market positions on behalf of brokers. All activities that could potentially affect cash or market positions must be recorded by making calls on the Accounting API. Summaries of accounts, along with all new transactions, are sent to brokers at the end of each timeslot.

    Accounting is also a TimeslotPhaseProcessor, running in the last phase of the simulation cycle. All processors that can generate transactions must run in earlier phases.

      • addCapacityTransaction

        CapacityTransaction addCapacityTransaction​(Broker broker,
                                           int peakTimeslot,

        kWh - total net demand among broker's customers during timeslot
        fee - assessed capacity fee for this peak event

      • addBalancingTransaction

        BalancingTransaction addBalancingTransaction​(Broker broker,
                                             double imbalance,

      • getCurrentNetLoad

        double getCurrentNetLoad​(Broker broker)
        Returns the current net load represented by unprocessed TariffTransactions for a specific Broker. This is needed to run the balancing process.

      • activate

        void activate​(org.joda.time.Instant time,
              int phase)
        Runs the accounting process. This needs to be here to support some tests
