This paper presents the Simplified Simulation Technique that evaluates the adequacy of an electric power system using only a portion of the outage period instead of each hour. Reliability evaluation may be performed at various hierarchical levels, generation, transmission and distribution system. The Simplified Simulation Technique simplifies the adequacy evaluation process reducing the number of calculations considerably. Therefore the computation time can be significantly reduced. This paper is done to compare the results of the simulation model with the Simplified Simulation Technique against the results of the simulation model without the Simplified Simulation Technique. The reliability indices such as the Loss of Load Probability(LOLP), the loss of load frequency(LOLF), the average duration of load curtailment(DLC) and the average demand of load curtailment(ADLC) are calculated. The proposed methods and procedures are tested by using the IEEE-RTS with 24-bus system.
