Comparison of SMES and RFB Performance in Combined Voltage and Frequency Regulation of Multi Source Power System

The analysis comported in this paper has been directed towards a novel control strategy in achieving the simultaneous regulation of voltage and frequency of a two-area multi-source power system (TAMSPS). The black widow optimization technique (BWOT) based integral-double derivative plus filter (IDDF) controller is suggested for combined voltage and frequency control. The investigation on TAMSPS is carried out by injecting the disturbance in a step load of 10% (SLD) in area-1. However, the efficacy of BWOT-based IDDF is validated with other controllers. Further, the investigation is stretched out with the integration of energy storage devices (ESDs) like redox flow batteries (RFB) and superconducting magnetic energy storage (SMES) with TAMSPS in both areas. Simulation results reveal the efficacy of RFB over the SMES device in attaining better dynamical behavior of the TAMSPS system under disturbed conditions.
