Investigations on power system operation and management in restructured market

Abstract

Traditionally, in many countries, electrical power industry has been struc- tured in a vertically integrated manner. The generation, transmission and distribution of electric power are totally controlled by large utilities within the region of their operation, where these utilities are the only providers of electricity. In such market scenarios, utilities have to operate within the policies, guidelines and regulations of the government while being assured of minimum pro t without any risk. This assurance has led to incompetent and sluggish attitude in the industry with lack of motivation for technical innova- tion, e cient management and customer focus. To overcome these drawbacks of the monopolistic market, most of the utilities are getting restructured. This work addresses some of the technical challenges encountered in the restructured market such as optimal power ow (OPF), determination of total transfer capability (TTC), available transfer capability (ATC), transmission pricing and congestion management. New algorithms based on di erential evolution have been suggested to solve these problems and the results are compared with other methods
