As the photovoltaic (PV) industry continues to evolve, advancements in Energy storage inverter voltage regulation have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
However, a developed control scheme with an energy-storage system can allow the inverter to operate in the reactive power mode even without the PV panels harvesting solar energy. Subsequently, the inverter can be programmed to operate as a VAR compensator to inject only the required reactive power, which will regulate the voltage at the load end.
Besides, the generator excitation system and inverter control circuits affect the system''s stability over time, and these effects may overlap. New findings have demonstrated adverse interactions between power converters and SGs excitation (primary voltage regulation equipment), deteriorating voltage stability at some degrees [16].
The ESSs can inject/absorb the reactive power also and that can be the main control approach to mitigate voltage rise issue in distribution networks (Rouco and Sigrist, 2013).This feature can be managed by inverter׳s ESS using the available capacity at a specific moment in accordance with the demand of the electrical grid.

1 INTRODUCTION. The renewable energy is important to cope with energy crisis and environmental pollution. As one of the most widely used resources, the solar energy will increase to very high penetration level [] this situation, the photovoltaic (PV) inverter has more responsibility in reducing the disturbance from PV array and support the grid voltage.
Under a power-limiting scenario, priority is given to power regulation through energy storage to absorb the limited active power. When the SOC of the BES reaches the upper limit of charging, modification of the PV MPPT algorithm facilitates the inverter output power to meet the power limit requirements.
The renewable systems with energy storage systems and smart inverters supply the reactive power to the system or provide ancillary services for the low-voltage networks without any auxiliary equipment. The Volt-Var (VV) control method is implemented by the inverter to maintain the dynamic voltage regulation.
