Flower pollination algorithm to solve dynamic economic loading of units with practical constraints

Abstract

Dynamic economic load dispatch (DELD) aims to obtain optimum generation schedule of the committed generating units’ output over a certain timing horizon, sustaining practical restrictions and power demands in each period. Valve-point effect, the ramp up/down limits, prohibited operation zones IPOZs), and power losses form the DELD as a complex, non-linear liable problem. The Flower Pollination Algorithm (FPA) is therefore anticipated in this paper to solve such a complex issue. The practicality of the proposed FPA method is assessed by conducting simulations at different load patterns on standard 5-unit and 10-unit systems for a 24-hour schedule. The FPA’s simulation results are related to other previously published biography techniques. These results clearly show that the skill and robustness of the proposed FPA method to solve the non - linear DELD problem has been restricted.
