Infinite Impulse Response Peak Filter with Salp Swarm Optimization Technique for Improvement of DVR Reliability

This chapter discusses theReliability reliabilityReliability aspects ofOptimization a dynamic voltageVoltage restorer (DVR) using an infinite impulse responseResponse (IIR) peak filter with linearLinear/nonlinearNonlinear loadsLoad to control voltageVoltage sagSag/swellSwell, voltageVoltage sagSag unbalance, and voltageVoltage harmonicsHarmonics. The proposed IIR filter control algorithmAlgorithms is used to estimate the fundamental active and reactive powerReactive power components of source voltagesVoltage and estimate the reference load voltagesLoad voltage. This chapter uses the Salp Swarm optimizationOptimization (SS) technique for determining optimized Kp and Ki gains of proposed control for the generation of reference load voltagesLoad voltage. This proposed SS optimizationOptimization technique-based DVR is modeled and simulated using MATLABMATLAB R2020a and DVR reliabilityReliability analysisAnalysis is performed using Plexim software. The results demonstrate satisfactory performance of the DVR under varying loadsLoad and also show improvement in the lifetime of the DVR.
