Interface Accounting

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.

Adds a distribution transaction to represent charges for customer connections and energy transport.

addCapacityTransaction

CapacityTransaction addCapacityTransaction(Broker broker,
                                           int peakTimeslot,

Adds a capacity transaction to represent charges for contribution to a demand peak. One is generated for each peak event.

Parameters:

broker -

peakTimeslot - when the peak occurred

threshold - assessment threshold

kWh - total net demand among broker's customers during timeslot

fee - assessed capacity fee for this peak event

void postBalancingControl(BalancingControlEvent bce)

Updates a broker's cash position resulting from the Balancing Market payment for Demand Response exercise.

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.

Returns a mapping of brokers to total supply and demand among subscribed customers.

Returns the market position for the current timeslot for a given broker. 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
