Plug-in Electric Vehicle Supported DVR for Fault Mitigation and Uninterrupted Power Supply in Distribution System

摘要

Now a days the electric vehicles usages is gaining popularity because of the pollution caused by existing and conventional IC engines. Electric vehicle integration to the distribution grid is increased at a faster rate because it can act as power backup to the grid. Thereby reducing the peak load and filling the valley point. This paper proposes the power backup of EV is utilized as an UPS to Software Company as well as used to support the Dynamic Voltage Restorer (DVR) to mitigate the fault occurring in the distribution system. It is known that most of the software engineers own a Electric car. The Batteries in the car is connected to the charging point (or) grid with monitoring of State of Charging (SOC) facilities in the parking area of company. When the Renewable power (solar energy) is available, the batteries will be charged to hundred percentage of SOC. Then excess power from PV will connected to load as well as grid. When the electrical power supply cutoff the car batteries will act as a battery bank of UPS and support to the critical load with condition based Allowable SOC. The total capacity of the batteries depends upon the no of cars available at a particular shift in a day. The entire system is modeled using MATLAB SIMULINK, the real time controllers are done by Raspberry pi development board and the results prove the feasibility of the proposed idea.
