OPTIMAL ALLOCATION OF DISTRIBUTED RESOURCES CONSIDERING CUMULATIVE VOLTAGE STABILITY INDEX FOR POWER DISTRIBUTION NETWORK USING TLBO

The development of various distributed resources will bring new challenges to traditional power distribution network. Traditional power generation has been slowly shifted to small distributed generation at load end to reduce carbon emission and improve performance of the power system. In restructured environment distribution utility continuously increases penetration of various distributed resources which need to be analyzed through various aspect for getting cost effective solution. Size and location of various types of Distributed generators and Reactive power compensator devices across distribution network plays a significant role in loss minimization, voltage profile and stability improvement. Thus distribution utility is required to address placement problem to get most economical solution for specific investment. Enhancement of voltage stability is also equally important aspect considering future load growth. This paper presents novel approach to address Distributed Generators and Reactive power compensators placement problem across distribution network considering different objectives. A multi objective function is created to look after loss minimization, investment-cost minimization and voltage stability enhancement. Proposed technique has been applied on IEEE-33 bus radial distribution network. Meta heuristic based TLBO algorithm is used to find optimal solution. Analysis has been extended for different cases with three different load level data to demonstrate effectiveness of proposed method
