Abstract
In this paper, a comparison of power systemfrequency response is conducted for a simple modelled powersystem with primary frequency control being provided either bysynchronous generators or by inverter-based Battery EnergyStorage (BES) systems. Mathematical models of conventionalgovernor and turbine are developed, representing conventionalsynchronous generator frequency control, and are used toillustrate system frequency response for a range of typicalconventional generating units. A mathematical model of apower-electronics interfaced Li-ion BES system is developedand used to represent a non-synchronous inverter-basedgenerator with primary frequency control capabilities.MATLAB/Simulink is used to build a model of a small powersystem, and simulations are carried out with at a range of typicalconventional synchronous generating units with a nonsynchronous generating unit in the power system. Thesimulation results demonstrate that the BES can be used forprimary frequency control providing a faster and betterresponse. BES is also capable of almost eliminating frequencyovershoot and reducing 70% of settling time while providingprimary frequency control in power system with various typesof conventional synchronous generating units and a nonsynchronous generating unit.
