Generation Adequacy Evaluation Using Discrete Convolution

This chapter describes the process of generation adequacy evaluation using the method of discrete convolution. In this process, the transmission facilities are assumed capable of transporting the generation to load points. The focus is on the evaluation of adequacy of generation resources. The method of discrete convolution consists of building generation and load models in the form of probability and frequency distributions of the random variables representing the total system generation and the total system load. A more practical method, called the Unit Addition Algorithm, is used for systems with large numbers of generating units. The load model, like the generation model, consists of probability and frequency distributions of the random variable representing the total system load. The generation reserve model consists of the probability and frequency distributions of the random variable, representing the generation reserve margin.
