Abstract

In this paper, a partition approach algorithm (PAA) is developed to solve economic dispatch with valve-point effect. The PAA developed integrates the multi-section divided and interval elimination method to search the optimal problem. The populations produced of PAA are model by parameters interval and divided sections to calculate the combinations of effective factors and their selected rules. The analysis of results uses a signal-to-noise ratio (S/N ratio) to aid in the determination of the offsprings. PAA is demonstrated on an example system with valve-point effect and compared to that of SA, GA, and EP. Results can be shown that the proposed method is more effective than other evolutionary algorithms and has a best probability to guarantee a global optimal
