Class Battery

java.lang.Object

org.powertac.customer.AbstractCustomer

org.powertac.customer.model.Battery

All Implemented Interfaces:

CustomerModelAccessor

@Domain
 @ConfigurableInstance
public class Battery
extends AbstractCustomer
implements CustomerModelAccessor

Models a single grid-connected storage battery with configurable capacity, max charge rate, max discharge rate, and efficiency. Batteries do not charge unless used for regulation, so repeated use for up-regulation will leave them discharged, and repeated use for down-regulation will leave them fully charged. If not used at all, they will eventually end up completely discharged just in case their selfDischargeRate values are non-zero. The initial state-of-charge is always 0.0;

Constructor Detail

Battery

public Battery()

Default constructor, requires manual setting of name

Battery

public Battery(String name)

Standard constructor for named configurable type

Method Detail

initialize

public void initialize()

Initialization must provide accessor to Customer instance and time. We assume configuration has already happened. We start with the battery at its targetSOC.

Overrides:

initialize in class AbstractCustomer

getCustomerInfo

public CustomerInfo getCustomerInfo()

Description copied from interface: CustomerModelAccessor

Returns the CustomerInfo instance for this customer model.

Specified by:

getCustomerInfo in interface CustomerModelAccessor

step

public void step()

Description copied from class: AbstractCustomer

Called to run the model forward one step.

Specified by:

step in class AbstractCustomer

getName

public String getName()

Description copied from class: AbstractCustomer

Returns the name of this model

Overrides:

getName in class AbstractCustomer

setName

public void setName(String name)

Description copied from class: AbstractCustomer

Sets the name for this model

Overrides:

setName in class AbstractCustomer

setCapacityKWh

@ConfigurableValue(valueType="Double",
                   description="size of battery in kWh")
 @StateChange
public void setCapacityKWh(double value)

getCapacityKWh

public double getCapacityKWh()

setMaxChargeKW

@ConfigurableValue(valueType="Double",
                   description="maximum charge rate")
 @StateChange
public void setMaxChargeKW(double value)

getMaxChargeKW

public double getMaxChargeKW()

setMaxDischargeKW

@ConfigurableValue(valueType="Double",
                   description="Maximum discharge rate")
public void setMaxDischargeKW(double value)

getMaxDischargeKW

public double getMaxDischargeKW()

setChargeEfficiency

@ConfigurableValue(valueType="Double",
                   description="ratio of charge energy to battery energy")
 @StateChange
public void setChargeEfficiency(double value)

getChargeEfficiency

public double getChargeEfficiency()

setSelfDischargeRate

@ConfigurableValue(valueType="Double",
                   description="hourly charge lost as proportion of capacity")
public void setSelfDischargeRate(double value)

getSelfDischargeRate

public double getSelfDischargeRate()

getBrokerSwitchFactor

public double getBrokerSwitchFactor(boolean isSuperseding)

Description copied from interface: CustomerModelAccessor

Returns the inconvenience of switching brokers. The value may depend on whether the current subscription is being switched to a superseding tariff as a result of revocation.

Specified by:

getBrokerSwitchFactor in interface CustomerModelAccessor

getTariffChoiceSample

public double getTariffChoiceSample()

Description copied from interface: CustomerModelAccessor

Returns a [0,1] random value used to make choices using the logit choice model.

Specified by:

getTariffChoiceSample in interface CustomerModelAccessor

getInertiaSample

public double getInertiaSample()

Description copied from interface: CustomerModelAccessor

Returns a [0,1] random value used to choose whether individual customers evaluate tariffs or not.

Specified by:

getInertiaSample in interface CustomerModelAccessor

evaluateTariffs

public void evaluateTariffs(List<Tariff> tariffs)

Description copied from class: AbstractCustomer

Called to evaluate tariffs.

Specified by:

evaluateTariffs in class AbstractCustomer

getShiftingInconvenienceFactor

public double getShiftingInconvenienceFactor(Tariff tariff)

Specified by:

getShiftingInconvenienceFactor in interface CustomerModelAccessor

getCapacityProfile

public CapacityProfile getCapacityProfile(Tariff tariff)

Description copied from interface: CustomerModelAccessor

Returns a capacity profile for the given tariff. This must represent the usage of a single individual in a population model over some model-specific time period.

Specified by:

getCapacityProfile in interface CustomerModelAccessor
