Feasibility Study on Improving the Ability of Wind Power Consumption of Micro-grid by Using Small Pumping Capacity
In view of the lack of wind power consumption capacity in the new energy micro-grid system, this paper will use small pumping storage as the energy storage system and the new energy micro-grid system to form a wind pumping and storage joint power generation system,effectively enhancing the system inertia of the micro-grid and increasing the economic benefits of the micro-grid. Firstly, a joint system combining wind power and then a comprehensive economic benefit calculation model including various costs and benefits was established. Finally, the optimal small pumping allocation plan was selected with the maximum annual comprehensive benefit to optimize the dispatching of wind power and small pumping resources. Case analysis shows that small pumped storage has good economic rationality when its unit capacity cost is not more than 6 times as much as that of traditional pumped storage. It indicates feasibility of small pumped storage in solving wind power accommodation problem.
