Analysis of Electric Vehicle Charging Station Allocation in Deregulated Electric Power System

Abstract:

At present, the transportation division experiences an upset, wherein low carbon and green environment are the main objectives. Electric Vehicles (EVs) are the future of transportation sector. The promotion of EVs(EVs) has carried an undeniably overwhelming weight to the installation of charging stations. To satisfy the need of rapid energy supply during the driving time frame, it is important to set up fast charging station in open territories (public areas). However, the random arrival of EVs to the charging stations, and interface with the grid network for fast charging,causes power fluctuations and peak-valley loads every now and again, thus causing disturbance in the power system. This paper centers around establishment of fast charging stations in the power system, a contextual study of the IEEE 24- bus system. This paper shows the siting of charging stations in four different test cases with power ratings of 5MW, 25MW, 50MW, and 100MW onto the load bus lines without violating the voltage magnitude limit (0.95-to-1.05) and the line ratings. Newton’s Raphson method is used for power flow calculation and to maintain the integrity of the network system.
