Abstract

This paper analyses impact of different load types on voltage stability of a power system with wind power. To analyse voltage stability, dynamic as well as static voltage stability assessment are performed. Dynamic model of wind turbine based on Type 4A IEC 61400-27-1 is used to develop an aggregated wind power plant model including the wind power collection system. Polynomial load model is used to represent different load types, namely, constant impedance, constant current and constant power loads. With respect to voltage stability assessment to determine stability of a particular operating point. Voltage collapse proximity indicator is used as dynamic voltage stability assessment tool to analyse the proximity of an operating point from voltage collapse. Impact of load type on voltage stability is discussed. Impact of reactive power support from wind power plant for the different load types is analysed and discussed. From the case studies performed, it is observed that effect of reactive power support from WPP varies depending on the load type. Results show that distance to instability for the same reactive power support from WPPs can be greater in case of voltage dependent loads than that of constant power loads.
