Transmission planning considering reliability and economic performances in a deregulated environment

The optimal design of transmission system expansion planning is an important part of the overall planning task of electric power system under competitive electricity market environments. Taking the cost-benefit analysis theory in economics as a basis, this paper analyzes the economy and reliability of the power transmission network at the beginning. Then, a mathematical model cost/benefit is proposed, and it is calculated by genetic algorithms which is introduced in section IV. Finally, it is tested and analyzed by Gaver-6-node system. Furthermore, the results indicate the feasibility and effectiveness of the method proposed in the paper.
