Market operations in future Indian restructured power system scenario

Abstract

Indian power industry is undergoing deregulation at a rapid rate. In this transition phase, it is now essential to design the most appropriate market and suitable pricing schemes for the power sector. In this article, a restructured electricity market model for future Indian power market is explained which is based on the institutional frame work – The Indian Electricity Act 2003. The activities of the three-tier market model and the entities involved in the power trading are discussed. Inter-regional and intra-regional congestion management scheme that provide comparable access to all users of the transmission system is proposed. Method for estimation of transmission charges to wheel electrical energy through transmission utilities is also proposed. The method is tested with a five region eleven zone Indian power system model and the results are illustrated.
