Abstract

Electric vehicle load is an emerging load into power systems. Understanding behavior of such new loads and evaluation of their impact on power system stability and security are of significant importance. This paper examines the influence of load voltage dependency on power system low frequency oscillatory stability. The impact is evaluated analytically for a range of voltage dependent load characteristics. The numerical study on a single machine infinite bus system evaluates the impact of EV load on system oscillatory stability and the results are compared with conventional system load models. The study identified that electric vehicle load is having a higher impact on system oscillatory stability compared to conventional loads.
