Multiobjective tradeoff analysis of deregulated electricity transactions

This paper analyzes the tradeoff relationships between the differing goals of power system operation and the influence of social policies, such as environmental impact minimization, upon deregulated electricity trade. An optimization procedure to reach a coordinated solution between different objectives is presented based on fuzzy interactive multiobjective optimization. Numerical examples are demonstrated on an IEEE 30 bus system. From the simulation, it has been found that the additional goals may reduce the volume of free trade of electricity, but the fuzzy multiobjective optimization can reach a good balance between conflicting goals.
