Integration of Electric Vehicle in Smart Grid and Manage Power with Demand Response /

Abstract

With the increase in the number of automobiles on the road, pollution increased that is why environmental concern is the main focus. There is a need to introduce electric vehicles in the market. Electric Vehicles penetrate the grid as a load and their integration causes high peak demand at the distribution side. Due to such high demand, it causes overloading at the distribution transformer. In this paper, mainly focus on the different charging profile of EV impacts in the distribution transformer. Level 1, level 2, and level 3 are the charging profiles which act as a load and these have different impacts on the transformer. In this study, observe each charging profile impacts and try to reduce them using the technique known as Demand Response. To accommodate EVs in the system there is a need to upgrade the distribution system which is a costly solution. Demand Response (DR) is the solution that improves transformer usage. In the DR technique customer load preference and privacy, these two things are major concerns. Simulate the whole day household appliances in the MATLAB/SIMULINK and observe the loading in the distribution transformer. Then apply Electric Vehicle (EV) load on the distribution transformer and observe when transformer is overloading. By using the power management tool known as Demand Response and reduces the overloading. All the simulated results are attached below.
