【 摘 要 】

This research work proposes a hybrid dragonfly algorithm and pattern search (hDA-PS) technique to optimize the parameters of two-degree-of-freedom proportional integral derivative controller (2dof-PID) for load frequency control of multi-microgrid (MG) system. The multi-MG contains power pool of photovoltaic (PV), wind turbine (WTG) and diesel engine generator along with different energy storage devices like battery energy storage system and flywheel energy storage system. The frequency control problem under the influence of stochastic disturbance condition is formulated as an optimization problem, and hDA-PS is implemented to search for the optimal controller parameters. To demonstrate the supremacy of the proposed 2dof-PID controller, the performances of 2dof-PID controller are compared with conventional PID and PI controllers. A comparative study with particle swarm optimization, genetic algorithm and dragonfly algorithm is done to justify supremacy of hDA-PS algorithm.
