ANALYSIS OF POWER SYSTEM UNDER DEREGULATED ENVIRONMENT

Abstract

Electric power sector in the, world has been changing dramatically to encourage competition among private sector generators and which leads to multiple number of bilateral transactions. It is important for both the end users such as, owners and customers to know and select the best possible and economic transaction. In the proposed dissertation selection of best transaction in a deregulated power system has been determined using Available Transfer Capability (ATC) and Short Term Marginal Cost (STMC). In the proposed algorithm ATC and STMC have been calculated using gradient based optimal power flow and continual power flow algorithms. The proposed algorithm has been tested and analysed for IEEE 30 bus reliability test system and the results obtained are found to be quite encouraging.
