Solar and Wind Power Estimation and Economic Load Dispatch Using Firefly Algorithm

In this paper, economic load dispatch problem is discussed and implemented with firefly algorithm optimization technique to obtain the best optimal solution for the fuel cost of generator. Moreover, we have included the renewable sources in ELD problem, by estimating generation of solar and wind power through probability density function including the underestimation cost and overestimation cost of wind and solar units. In this problem it is been assumed that the renewable source units are located near the load center; hence we are neglecting the transmission losses by renewable sources and considering them only for the coal fired units (thermal units). The problem is then executed on four test cases with and without inclusion of renewable sources along with different combinations of renewable sources and validated them with experimental approach.
