Job description

The increasing number of electric vehicles(EV) presents an ideal opportunity to improve grid stability. EV helps reduce the use of fossil fuels for commuting purposes. Bi-directional chargers connect EVs to the grid to present a virtual energy storage system through the vehicle to grid (V2G) technology. The frequency and voltage fluctuations in the grid due to sudden changes in electricity requirement can be satisfied from the energy stored in EV within microseconds. My research studies the strengths and limitations of EV and V2G to improve grid stability. A simulation model is developed in Simulink software. Renewable sources such as Wind, PV and hydro powerplants, and EV and pumped hydro systems were considered for energy storage in the model. The main focus area of the research will be

  • How grid stability varies with un-controlled EV charging?
  • Is V2G a viable energy storage option?
  • Through V2G, is it possible to solve grid issues due to peak loads?
