Impact of Electric Vehicle Load and Wind Farm on Small Signal Stability

Abstract

With the integration of Electric Vehicle (EV) into power systems results in an instability behavior due to the addition of emerging load. This paper examines the impacts of EV load on small signal stability which is significant issues. Due to the EV load, system stability is reduced and resulted in instability for further disturbance. The instability is occurred due to inadequate damping in the generator. It is improved by adding Wind Farm (WF) which can be delivered significant active power. With WF. It reduces the overall inertia of the generator due to the participation of the machine is decreased. The test system is also analyzed with Power System Stabilizer (PSS) and noticed that stability is further enhanced. The obtained results are compared with and without WF and PSS and their combination. It is observed from the result that EV load is having a higher impact on system stability. Overall stability is enhanced by adding PSS and WF into the system. The stability is carried out by considering a two-area test system.
