چکیده انگلیسی

Economic dispatch (ED) generally formulated as convex problem using optimization techniques. Various methods have previously been used for the solution of the problem. Among those Tabu search (TS), evolutionary programming (EP), and genetic algorithm (GA) are powerful methods but they are heuristic and do not always guarantee to achieve to global optimal solutions in finite time. They take longer time to converge to near optimal results. Reaching to the optimal solution faster depends on how the methods are programmed and applied. This paper proposes new simple approach to solve the economic dispatch problem with valve-point and losses effect. The proposed method is an optimization algorithm which minimizes the total cost of the plants and gives optimum generation schedule subject to the operating constrains of the system. It is based on valve-point active powers for different combinations of valve-points in all generation units. Three machines 6-bus system, IEEE 5-machines 14-bus, and IEEE 6-mchines 30-bus systems have been tested for validation of our approach. Results of the proposed scheme compared with results obtained from genetic algorithm (GA), hybrid genetic algorithm (HGA), and hybrid (H) method give significant improvements in the generation cost that confirm the applicability of the proposed method.
