Multi-Port Solar Power Plant with Battery Storage using a Voltage Source Inverter

Abstract

Electricity production is rapidly increasing because of the hike in the usage of electricity. The electricity is produced widely by non-renewable power plants. These non-renewable power plants explicating harmful gases and solid waste to the world. To minimize the emission of harmful gases, we are subjected to the use of Renewable Energy Resources. Variable renewable resources are available like Wind power, Biomass, Tidal waves, Hydro power, Solar power, etc. Photovoltaic (PV) systems convert sunlight into electrical energy using the photoelectric effect. PV products are unique among renewable sources. These systems work by converting incident solar energy directly into electricity through photovoltaic modules made of semiconductors. Sun’s radiation is converted directly into Direct Current (DC) by the photovoltaic Diodes and then inverted into usable Alternating Current (AC) through the Voltage Source Inverter (VSI). An impact leveling management system is planned to transfer power to the load and by the ESS to load when the solar irradiation is not on the demand level. The primary goal of this paper is to achieve continuous power flow to electrical equipment by using an Artificial Neural Network (ANN) controller with improved Maximum Power Point Tracking (MPPT) algorithm is used to extract the maximum power from the solar during the Sunshine hours, ANN controller control and monitor the power flow from the solar to the load. When solar irradiation is not prevalent, ESS behaves as a counterpart to compensate for the continued operation of the electrical load by injecting balance voltage to the boost converter to increase the conversion efficiency.
