Generation dispatch of combined solar thermal systems using dragonfly algorithm

This paper presents a method to solve Static Economic dispatch incorporating solar energy using Dragonfly algorithm. Economic dispatch is carried out considering valve point loading and prohibited operating zone constraints. Solar energy system is modelled using Beta distribution function and included in the objective function. The output power of solar farm is forecasted for four seasons. Different loading conditions are assumed in various seasons for the detailed analysis. Dragonfly algorithm, an emerging optimization technique for constrained optimization problems is applied as the optimization tool here. The proposed method is validated in 6 generator, 15 generator and 17 generator practical south Indian test systems. The results are compared with the state of art heuristic optimization method available in the literature.
