Energy Management of an Isolated Wind/Photovoltaic Microgrid Using Cuckoo Search Algorithm

This paper introduces a renewable-energy-based microgrid that includes Photovoltaic (PV) energy and wind generation units. Also, an storage system is present. The proposed loaded with constant load impedance. To improve the performance of microgrid, optimal control algorithm utilizing Cuckoo Search Algorithm (CSA) adapted. It has many merits such as fast convergence, simple tunning, high efficiency. Commonly, PV energies are suitable for supplying loads under normal conditions. However, recovers excess demand. frequency voltage regulated using CSA controller. responses introduced controller measured step changes in demand, power, irradiation level. Matlab simulations carried out to test performance. simulation results showed fed Alternating Current (AC) power amplitude all disturbances. Moreover, required demand been perfectly compensated. excellent unstable speed variable solar irradiation. compared those Particle Swarm Optimization (PSO) at same also found provides better responses.
