In distributed power generation systems energized by multiple renewable energy systems, the harmonics injected by grid connected inverters are seriously affected by the grid uncertainties at the point of common coupling. As several inverters are tied with a single grid, the grid impedance can cause more harmonics and serious damages. Hence at this stage phase locked loop based on phase estimation method must be considered. This paper therefore proposes Integral Control Phase Estimation (ICPE) method as a better solution than Sine Wave Pulse Width Modulation (SPWM) using single phase half bridge grid tied inverter. Three parameters including voltage, phase and frequency are normally used from the grid side converter (GSC) to synchronize battery powered machine side converter (MSC). Here the framework is implemented by estimating only grid side phase and frequency using dynamic quadrature (DQ) rotating frame of reference and thus forming the phase-locked loop (PLL). The THD thus obtained from our proposed technique is around 0.3 , which dominates conventional SPWM. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
