Sliding Mode Controller for Parameter-Variable Load Sharing in Islanded AC Microgrid

Controlling voltage, frequency, and current in an islanded microgrid is a challenging problem because the distributed generation sources, stochastic intermittent nature, are not connected to main electricity network provide stable clean energy. Therefore, design of robust controller control output parameters suppress load variations disturbances essential. In this paper, hysteresis proposed designed voltage AC improved sliding mode (SMC) based on adaptive principle microgrid. The consists two parts: An adaptation part, which aims eliminate system uncertainties, second deal with tracking under parameter-varying topologies. strategy has advantage solving gain tuning chattering reduction. It also requires limited information about disturbance uncertainties system. To validate methodology show its effectiveness, case study simulated presented. results that controllers can effectively underload changes increase stability resilience reveal performance terms total harmonic distortion (THD) dynamic response overcome conventional by 4× reduction THD 40–200× settling time.
