Storage System for Solar Plants

Abstract

Power supply to consumers, especially in remote areas, is often subject to emergency power outages. This leads to numerous problems such as the breakdown of household appliances and electronics, the inability to provide vital functions in homes and special institutions, and production failure. Also, grid companies sometimes cannot efficiently provide energy to private consumers due to insufficient capacity of the power grid. This journal discusses the use of power plants on alternative energy sources and systems of accumulation of electric energy connected to renewable energy sources. Such systems can be used in parallel with the existing electric power grid, as well as directly by autonomous consumers. This journal also describes the possibility of providing electric power to individual consumers using solar panels in combination with a system of accumulator batteries. The process of charge–discharge of capacitive batteries in the photovoltaic module–battery system is studied in order to increase the efficiency of low-power autonomous power plants. Studies show an increase in the efficiency of the system designed for the individual consumer by 30%, as well as the possibility of uninterrupted operation. The proposed model of the combined photovoltaic and storage system avoids the problems associated with emergency power outages. More importantly, for various Russian Federation regions that are neither close to the generating facilities nor have reliable uninterrupted electricity supply, the presented system can significantly extend both the time of efficient use of energy resources and the service life of the equipment.
