The major difficulty in the adequacy evaluation of a practical power system is the computational time involved in solving a large number of ''credible'' outage events. The overall requirement is dependent upon the load and generation profile of the power network, the topology, failure and repair rates of the network components and the intent behind the adequacy studies. It has been illustrated that, for moderately sized networks such as the IEEE Reliability Test System (RTS) and the Saskatchewan Power Corporation (SPC) system, the effect of outages involving four or less than four generating units and/or two or less than two transmission lines is quite predominant and their contribution is too significant to be ignored. The inclusion of further outages beyond these levels, if required, results in very high computational times even for moderately sized networks such as the RTS and the SPC systems. This paper presents a technique to study the adequacy performance of a small area (Area of Interest-AI) in a power network. This approach can be very useful in large power networks as it is sometimes necessary to perform detailed adequacy analysis of selected and relatively small regions of a network.
