Abstract

This paper proposes the use of the Energy Storage System (BESS) to improve the voltage stability on a small-scale South African network with a large amount of wind power generation; under both steady-state and fault conditions. Pumped-Hydroelectric Storage (PHS) and BESS were selected and compared in DIgSILENT PowerFactory 2018 simulation software. Mathematical models and block models of the network components, BESS and PHS models were developed and tested under steady-state operation, thus, three cases were studied which included the network with wind power generation, then with wind power generation and BESS and finally with wind power generation and PHS.

Results under steady-state conditions showed that the voltage levels for the four loads were within the acceptable standard voltage limits of 0.95 p.u. and 1.05 p.u. across all three cases. Thus, it was concluded that BESS is the most suitable EES for a network with a large amount of wind generation, as it displayed the capability of maintaining the voltage levels within the acceptable voltage limits under both steady-state and fault conditions.
