Evaluation of production cost of multi-area interconnected power system using segmentation method

Abstract

The evaluation of ABSTRACT reliability and production cost of each -I alternative potential plan are two essential steps in generation expansion planning. Utilities interconnect with each other to decrease the production cost and increase the reliability of the global as well as individual system. The methodology to evaluate the reliability and the production cost is well established for single area system and also quite efficient methodology is available for two area interconnected systems. However, an efficient methodology of evaluating interconnected systems (more the production cost for multi-area than two system ) has not yet been developed. This thesis presents a methodology to evaluate the production cost of multi-area interconnected electrical power systems. The methodology is an extension of the segmentation method for evaluating the production cost of two area interconnected systems. The accuracy of the developed methodology is justified through a small example which can be solved by using a pocket calculator. The methodology is also applied to a realistic interconnected system.
