Model of an ideal electrical battery energy storage.

Attributes, Units and Remarks

Type Model

Attribute	Unit	Remarks
uuid	–
id	–	Human readable identifier
capex	€	Capital expenditure to purchase one entity of this type
opex	€ / MWh	Operational expenditure to operate one entity of this type
eStorage	kWh	Battery capacity
sRated	kVA	Rated apparent power
cosPhiRated	–	Rated power factor
pMax	kW	Maximum permissible active power infeed or consumption
activePowerGradient	% / h	Maximum permissible rate of change of power
eta	%	Efficiency of the electrical inverter
dod	%	Maximum permissible depth of discharge. 80 % dod is equivalent to a state of charge of 20 %.
lifeTime	h	Permissible hours of full use
lifeCycle	–	Permissible amount of full cycles
em	–	UUID reference to an Energy Management Unit that is controlling this system participant. Field can be empty or missing, if this participant is not controlled.

Caveats

The field behaviour will be removed in version 1.x, as this is an information, that is only important to a smaller sub set of simulation applications.
