Imperialist Competition Algorithm for Solving Non-convex Dynamic Economic Power Dispatch

Dynamic economic dispatch (DED) aims to schedule the online generating units’ output active power most economically over a certain period of time, satisfying operational constraints and load demand in each interval. Valve-point effect, the ramp rate limits, prohibited operation zones (POZs), and transmission losses make the DED a complicated, non-linear and constrained problem. Hence, in this paper, Imperialist Competition Algorithm (ICA) is used to solve such complicated problem. The feasibility of the proposed method is validated for five and ten units test system for a 24 hour time interval. Results obtained with the proposed approach are compared with other techniques in the literature. The results obtained substantiate the applicability of the proposed method for solving the constrained DED with non-smooth cost functions.
