STATCOM+BESS MODELLING AND HARMONIC ANALYSIS

Abstract

In this paper, concepts of Static Compensator plus Battery Energy Storage System (STATCOM+BESS) operation, power control and modelling are reviewed. An implementation in Matlab-Simulink, considering a two level VSC based STATCOM+BESS is realized. Details of the implementation are provided and simulation results are presented. A single, aggregated 50 MVA BESS with the STATCOM connected to an external grid, is considered in the assessment. Harmonic propagation analysis is conducted by considering THD values at the point of connection of the STATCOM+BESS station.
