Abstract

This paper demonstrates voltage profile improvement by partitioning the Y-admittance and the application of circuit theory on power system networks. The partitioned Y-admittance matrix and eigenvalue decomposition technique were used to identify the suitable locations for reactive power compensators. The proposed approach was applied to the 40-bus Southwest England network and the results were compared with the classical Q-V sensitivity approach. The proposed approach improves the overall voltage profile towards the nominal voltage limit.
