Honey Bees Searching Optimization for Non Convex Dynamic Power Dispatch Problem in Thermal Units


Dynamic Power Dispatch (DPD) intends to schedule the online generators output with the forecasted load demand over a certain period of time, in order to operate an electric power system most economically within its operating limits. The behavior and the activity of honey bees during food foraging is implemented as a Honey Bees Searching Optimization (HBSO) technique in solving the DPD problem. The HBSO algorithm provides a balance between exploration and exploitation of a search space. Further, the HBSO is independent of control parameters when compared to other techniques. The DPD formulation includes ramp rate constraint, rectified sinusoidal effect, uniformity and disparity constraint, which normally present in the realistic power system. In order to express the efficacy of the HBSO algorithm a test case of 6 units DPD problem is considered and lower fuel cost is obtained when compared with other algorithm.
