Interconnection of Battery Charging Station and Renewable Energy in Electrical Power System

Abstract

In the future, vehicles that use fossil fuels will be replaced by electrical vehicles. The reason are fossil energy sources will be focused on electricity generation and besides that the availability of fossil energy is also running low. Another reason to prefer electrical vehicles is not produce air pollution or can be called environment friendly vehicle. There is an additional instrument to support the existence of electrical vehicles, namely battery charging station (BCS). Electrical vehicles use batteries as electricity storage. There are several electrical vehicles use hybrid system like uses battery, and solar panels on it to produce electrical energy. Based on these backgrounds, this article will discuss the about interconnection of battery charging station and renewable energy in electrical power system. Types of renewable energy in this paper are photovoltaic and wind power plant. Both of these power plants have role as distributed generation to help power system charge the BCS. In this study using standard 14 bus IEEE electrical power system. In the test method, several study cases will be made to be compared. The first study case is to analyze changes in voltage in the electric power system. The second study case is to analyze short circuit in the distributed generation to electrical power system. The final results of all scenarios will be compared to determine the impact of chargers, photovoltaics, and wind power plants when connected to the electric power system.
