Abstract

Aiming at the dynamic dispatching optimization of hybrid energy microgrids, a strategy-driven optimal dispatching method based on the combination of multi-mode dispatching strategy and dispatching incentive is proposed. The power complementation between the energy storage unit and the external power grid is realized, and the power output is optimized. Firstly, considering the basic structure of hybrid energy microgrids, a microgrid model is established. The objective function of minimizing operation cost and environmental remediation cost is proposed based on the constraints of climbing power, power unit output and energy conservation. Secondly, the dispatching strategy-driven model of microgrids is proposed based on the successful experience and expert knowledge, combined with dispatching incentive mechanism. Finally, MATLAB simulation and algorithm comparison show that the proposed algorithm has the characteristics of fast convergence, strong local and global search ability.
