Economic Emission Load Dispatch of Fixed Head Hydrothermal Power Systems Through an Interactive Fuzzy Satisfying method and Simulated Annealing Technique

摘要

A novel multi-objective optimization method for economic emission load dispatch of thermal plants with non-smooth fuel cost and emission level functions in coordination with fixed head hydro units is presented. In this paper, the problem treats economic and emission as competing objectives for optimal dispatch, which requires some form of conflict resolution to arrive at a solution. Assuming that the decision maker (DM) has imprecise or fuzzy goals for each of the objective functions, the multi-objective problem is transformed into a minimal problem, which is then handled by the simulated annealing (SA) technique. The solution methodology can offer a global or near-global non-inferior solution for the DM. Numerical results for a sample test system have been presented to demonstrate the performance and applicability of the proposed method.
