Abstract

This paper presents a case of applying STATCOM/BESS (battery energy storage system) stabilizers in a real large scale Chinese power system to alleviate inter-area power oscillations. As STATCOM/BESS can exchange both active and reactive power with power grid, stabilizers attached to a STATCOM/BESS is able to function to suppress power system oscillations via regulation of active or/and reactive power. Thus STATCOM/BESS stabilizers can be classified into two types, active stabilizer and reactive stabilizer. In the paper, firstly mathematical model of STATCOM/BESS installed in a multi-machine power system is described. The damping function of stabilizers attached to the STATCOM/BESS is analysed. Then a case of applying STATCOM/BESS stabilizers in a real large-scale Chinese power system is presented. Both the STATCOM/BESS active and reactive stabilizer is designed and their performance to suppress inter-area power oscillations is compared.
