Study of PV System for Electricity Production for Self-Consumption

Self-consumption for residential and industrial buildings is important in order to reduce energy consumption from the electricity grid. As energy prices rise, more and more consumers are installing PV systems for their self-consumption. Self-consumption systems have a number of specific difficulties to solve related to variations in solar energy production and the user's load profile. Each installed system will contribute to the reduction of CO2 emissions and encourage the installation of low-power PV systems to produce green energy. In this way, users will reduce their dependence on the use of energy from the mains. The aim of this work is to develop simulation model for calculation of energy balance of PV system for self-consumption. Comparison of performance of two PV system types is done - without and with battery storage.
