An Energy Method for Determination of Flicker Source at the Point of Common Coupling

In this paper a new energy method for determination of flicker source in power system is proposed This method is based on the energy of flicker signal; therefore, an expression for flicker energy signals is defined, which can be successfully utilized for detection of the flicker source. The main advantage of this method is its simplicity which can be implemented in time domain and no transformation to frequency domain is required. There are good agreements between simulation and test results.
