A New Approach Economic Dispatch Based on Genetic Algorithm Considering Ramp-Rate and Prohibited Operating Zones

This study introduces an algorithm designed to tackle the Economic Dispatch (ED) problem, specifically addressing power plant units with forbidden functioning zone restrictions and ramp-rate bounds. Initially, the algorithm prioritizes dispatching units with consideration for prohibited operating zones, though it initially overlooks ramp-rate limits. Units whose output powers fall outside their prohibited zones are considered optimal. These optimized outputs then serve as the basis for subsequent dispatch periods, which incorporate ramp-rate limits. The effectiveness of the algorithm was evaluated on systems featuring 15 and 40 units, accompanied by a comparative analysis against alternative algorithms. The findings demonstrate that the proposed algorithm efficiently achieves optimal power generation while adhering to operational constraints.
