Economic Operation of Islanded Microgrids Based on the Region Search Evolutionary Algorithm

In this paper a new evolutionary algorithm based on the region search evolutionary algorithm (RSEA) is developed for optimal energy management and operation of microgrids. Islanded microgrid operation is more crucial than the conventional distribution grids because of less dependency of the extremal (upstream) generation units. Thus, an effective economic operation of islanded microgrid need a strong algorithm to meet all constraint associated with the problem. The proposed developed RSEA technique is tested on the IEEE 33 bus test system. Results show the effectiveness of the RSEA technique, compared to the well-known evolutionary techniques.
