public Simulator()

Method Details

calculateCost

protected static double calculateCost(Params p,
 StateMachine[] schedule)

Simulates a Schedule and calculates the cost.

Parameters:

p - the Params

schedule - the StateMachine states of the Schedule

Returns:

the cost, lower is better; always positive

simulate

protected static com.google.common.collect.ImmutableSortedMap<ZonedDateTime,Simulator.Period> simulate(Params p,
 StateMachine[] schedule)

Simulates a Schedule in quarterly periods.

Parameters:

p - the Params

schedule - the StateMachine states of the Schedule

Returns:

a Map of Simulator.Periods

simulatePeriod

protected static double simulatePeriod(Params p,
 Params.OptimizePeriod op,
 StateMachine state,
 AtomicInteger nextEssInitial,
 Consumer<Simulator.Period> collect)

Calculates the cost of one Period under the given Schedule.

Parameters:

p - the Params

op - the current Params.OptimizePeriod

state - the StateMachine of the current period

nextEssInitial - the initial SoC-Energy; also used as return value

collect - a Consumer to collect the simulation results if required. We are not always collecting results to reduce workload during simulation.

Returns:

the cost, lower is better; always positive

getBestSchedule

protected static StateMachine[] getBestSchedule(Params p,
 long executionLimitSeconds)

Runs the optimization with default settings.

Parameters:

p - the Params

executionLimitSeconds - limit.byExecutionTime.ofSeconds

Returns:

the best schedule

getBestSchedule

protected static StateMachine[] getBestSchedule(Params p,
 long executionLimitSeconds,
 Integer populationSize,
 Integer limit)
