Distributed Energy Resources, like PV and Energy Storage inverters can provide voltage regulation support by modifying their reactive power output through different control functions including power factor, volt-var, watt-var, and watt-PF. This article delves into the control strategy and implementation of grid-forming solar inverters without energy storage support, based on power self-synchronization principles. Their control performance directly influences system stability and grid connection quality. By providing Volt/VAR control, frequency regulation, and ride-through capabilities, smart inverters. The accelerated integration of photovoltaic (PV) systems, particularly within Hybrid PV–Battery Storage Systems (PV-BSS), establishes a compelling need for advanced control strategies that are fundamental to achieving effective Energy Saving Management.
