Energy Management of Renewable Energy Sources in a Microgrid using Cuckoo Search Algorithm

In this paper, the Renewable Energy Resources (RES) are used in a specific small area which is known as microgrid. Microgrid consists of microsources, battery storage and loads. In this paper the research is focused on the islanded mode microgrid. In the microgrid, the energy management system having a problem of Economic Load Dispatch (ELD) and it is optimized by meta-heuristic techniques. The newly introduced Cuckoo Search Algorithm (CSA) is implemented for the solution of ELD problem in the MATLAB environment. The minimization of total cost is obtained for four different scenarios like all sources included, all sources without solar energy, all sources without wind energy and all sources without solar and wind energy. In both scenarios, the result shows the comparison of CSA with the Reduced Gradient Method (RGM) for the ELD problem solution. The results are calculated for different power demand of 24 hours. The results obtained with CSA gives better cost reduction in less iterations as compared to RGM which shows the effectiveness of the suggested algorithm.
