Abstract

The main purpose of this paper is to study the application of fuzzy modeling to the analysis of load characteristics in a power system. A fuzzy model is a set of fuzzy IF-THEN rules for describing system behavior. The method of fuzzy modeling is suitable for the analysis of load characteristic due to the nonlinear load curve. The Sugeno type fuzzy model is adapted in this paper. The fuzzy load model is capable of providing both quantitative and qualitative description for the customer under study and hence will be helpful to the task of analyzing load characteristic. Based on the fuzzy load model, we calculate the peak value, load factor, and consumption of the load curve to analyze the load characteristics. The effects of the fuzzy load model parameters on the load characteristics and load management strategies are also investigated.
