IMPROVEMENT OF METHODS FOR INCREASING THE ENERGY EFFICIENCY INDICATORS OF AN OFF-GRID SOLAR PHOTOVOLTAIC SYSTEM

Abstract

Globally, renewable energy sources are increasingly being utilized to supply consumers with reliable, high-quality, and continuous electrical power. In our country, special attention is given to ensuring uninterrupted electricity delivery and improving energy efficiency by developing solar photovoltaic systems that are well suited to the local climatic conditions. In addition, the effective planning and optimization of operating modes of existing energy systems are examined through an assessment of consumer requirements and established recommendations.This study investigates the optimal sizing of solar photovoltaic (PV) systems and battery energy storage (BES) units for a single configuration using a newly developed rule-based energy management strategy. Two system layouts are considered: (i) a PV-only system and (ii) a combined PV-BES system. The performance optimization of a grid-connected residential household is evaluated using one year of realistic operational data. Furthermore, uncertainty analysis is conducted by accounting for variations in solar irradiance, ambient temperature, and electrical load. Sensitivity analyses are performed with respect to average daily demand, grid limitations, and the cost parameters of PV and BES technologies.
