An efficient technique for reliability analysis of power systems including time dependent sources Academic Article uri icon

abstract

  • A method for reliability analysis of electric power systems with time dependent sources, such as photovoltaic and wind generation. is introduced. The fluctuating characteristic of unconventional generation units affects the reliability of the generation system in a different manner than the conventional units. The method proposed in this paper groups the units into several subsystems. One subsystem contains the conventional units and the remaining subsystems consist of unconventional units. The generation system model is built for each subsystem. The outputs of the unconventional units and the load are treated as correlated random variables. Using a clustering procedure, states are identified wherein for a given value of load. there are specific mean values of the outputs of the unconventional units. Reliability analysis is performed by combining the conventional subsystem with the unconventional subsystems in each state. The output from all the states is combined to compute the Loss of Load Expectation (LOLE) and Expected Unserved Energy (EUE). 1988 IEEE
