Abstract

The voltage sensitivity of the bus load is important data required for power system dynamic performance studies. However, it is not straightforward to determine the sensitivity coefficients because the bus load consists of a number of load components and network elements and because their composition changes with time, weather, customers' lifestyles, and other factors.<br> This paper describes a technique to estimate the voltage sensitivity coefficients. The technique was developed while studying the recorded bus load responses to naturally occurring disturbances. The voltage sensitivity coefficients of the Izusi 6.6kV bus load were estimated.
