A Technical Study on Energy Storage and Management for Grid Optimization in Isolated Areas

Abstract: The remote and mountainous regions face permanent problems with their electric network, such as stability problems, sudden drops in voltage and power quality that affect people’s daily life at home and their devices’ performance. The reasons for the poor quality of electricity are due to the aged, remote local distribution network and the often harsh weather conditions especially during winter months. Feeding the grid in reverse order is our proposed solution which will decrease electricity needs to be transmitted over great distances. Energy production in remote regions could be advantageous if it included the utilization of local renewable energy sources. The system of production, storage and management of energy could provide greater network stability which would then lead to better electricity quality, reduction of potential losses and failures under specific conditions. The present study focuses on the use of renewable sources to create a smart energy storage system with the goal to achieve the grid benefits analyzed. By examining currently available technologies and taking into account their potential commercial applications in the near future along with their costs, it appears that a promising approach is to use renewable in a hybrid mode combined with batteries for energy storage. The article develops an energy system (including photovoltaic, wind and hydroelectric power stations), which offers energy according to the demand in real time with appropriate modeling. The aim of the article is to create a system for producing, storing and managing energyby using renewable sources and batteries at minimal environmental impact.
