In this paper, a methodology to perform the optimal sizing for Distributed Energy Generators in MicroGird (MG) based on Cuckoo Optimization Algorithm (COA) has been improved to calculate the optimum system formation that can Accomplish the customers required Loss of Power Supply Probability (LPSP) with a minimum Cost of Energy (COE). The proposed method results are validated for single source DG and hybrid DG with results obtained from HOMER and COA in MATLAB for the same test systems.
