Integration of Electric Vehicles as Smart Loads for Demand Side Management in Medium Voltage Distribution Network

The distributed solar generation possess the potential to overcome the energy deficit in a power system network. However, its high penetration reshapes the system’s power flow and causes high fluctuations in voltages and frequency. To overcome the uncertainty and variability issues faced by the solar systems, storage plays a vital role. In this paper, Electric Vehicles (EVs) are used as a Demand Side Management (DSM) tool to mitigate the solar fluctuations. The behaviour of EV’s battery to act as a load/source is controlled by three parameters; State of Charge (SoC), output power from PV and system’s voltage. Different scenarios have been analysed on a 2MW distributed solar generation system integrated with an IEEE-33 bus radial network using MATLAB/Simulink. The results show that the over/under voltage conditions are mitigated and excess energy generated is utilized effectively by using EVs as a DSM tool.
