Research on Optimal Allocation of Microgrid System Based on Two Layers of Coordinated Dispatch

Abstract:

In the process of the optimal allocation of microgrid system, two layers of coordinated dispatch strategies has been used in this paper. In the first layer, diesel generators and batteries are coordinated dispatched each other. The diesel generators begin to work before state of charge (SOC) of batteries reaches the lower limit. In the second layer, the power of batteries and super capacitors are distributed based on the dynamic characteristics of the hybrid energy storage system. Based on the coordinated dispatch strategies, the optimization models of DGs in microgrid system are constructed which considers the comprehensive cost of system as the optimization objective function and adopts the reliability indexes as the constraints. Genetic algorithm is used to solve the objective function. With the example system, it verifies the correctness and effectiveness of the models, the algorithm and the coordinated dispatch strategies.
