Economic Load Dispatch Using Firefly Algorithm

Abstract

In this work, we have applied the Firefly Algorithm (FA) for some non-linear benchmark functions to highlight the efficiency of algorithm. Generalized Economic Load Dispatch (ELD)problem is discussed and implemented with firefly algorithm optimization technique. Then, we have included the renewable sources in ELD problem, by estimating wind and solar power generation through probability density function including the overestimation cost and underestimation cost of wind and solar units. In this problem we have assumed that the renewable source units are located near the load, hence we are neglecting the transmission losses by renewable sources and considering them only for the thermal units. The problem is implemented on the four test cases with and without inclusion of renewable sources along with different combinations of renewable sources and validated them with experimental approach.
