Effective Microgrid Cost Reduction using Dragon Fly Optimization Algorithm and Firefly Algorithm

Introducing distributed generation (DG) into distribution networks provide reliable power to the consumers. The dispatchable and non-dispatchable unit usually placed nearby distribution networks operates in medium/low voltage system. The dragonfly and firefly algorithm are used for micro grid optimal scheduling both in grid connected mode and island mode. Dispatchable and non-Dispatchable units in the micro grid are connected to the conventional grid to supply energy to the end user. The fire fly algorithm has a drawbacks to find the global minima and also they were not able to provide a proper balance between exploration and exploitation. The drawback of DA it does not give accurate optimal solution for multi-objective problem and it was not used for short term wind power prediction. To find the minimum operating cost of micro grid the protype is developed for Dragonfly and firefly algorithm. Comparative performance analyses are done with the results of DA and firefly algorithm. Here the Dragon fly algorithm outperforms firefly algorithm by evaluating with power demand and operating cost of micro grid
