DSA-Based Analysis for Capacitor Requirement of a Three-Phase Standalone Asynchronous Generator

This paper proposes an efficient algorithm for finding the lowest capacitance value needed to initiate no-load voltage establishment of a three-phase Standalone Asynchronous Generator (SAG) operating under variable speed. Additionally, variation of capacitance value with change in load power under constant voltage-speed operation has been observed. Differential Search Algorithm (DSA) has been enforced to find an optimal capacitance value required for the aforesaid mentioned operations. The results obtained using DSA have been compared with experimental results. It is observed that there is close agreement between the simulated results with the experimental values.
