Abstract
Modern energy systems are increasingly integrating renewable energy sources, presenting new challenges for voltage regulation. This study aims to model the voltage regulation process in the context of distributed electrical grids equipped with solar photovoltaic systems. A three-tier voltage control algorithm is proposed, which analyzes and integrates data on solar generation, suggests optimal actions for managing energy storage systems, calculates voltage levels, and recommends measures for controlling inverter reactive power to effectively mitigate voltage fluctuations. The study employs methods of mathematical averaging of time series and optimization based on the analysis of real data. The algorithm's performance is evaluated using an open dataset of solar energy generation. The results show a significant improvement in voltage regulation metrics, conforming to the standards established by GOST 32144-2013. This validates the effectiveness of the proposed voltage control method in electrical grids incorporating solar photovoltaic systems.
