Day-ahead market clearing system optimization operation method based on microgrid reference

The invention discloses an optimized operation method of a day-ahead market clearing system based on microgrid reference, and the method comprises the steps: achieving the lower optimization through amicrogrid self-optimization model, and building a microgrid source, load and storage coordinated optimization scheduling model taking the lowest system operation cost as a target. Upper-layer optimization is achieved through a day-ahead electricity market clearing model, and electricity market day-ahead clearing with social welfare maximization as the target is achieved. By implementing the invention, the stability and economy of the microgrid system can be improved. 本发明公开了一种基于微电网参考日前市场出清系统优化运行方法，通过微网自优化模型实现下层优化，可以建立以系统运行成本最低为目标的微电网源、荷、储协调优化调度模型；通过日前电力市场出清模型实现上层优化，以最大化社会福利为目标的电力市场日前出清。实施本发明，可以提高微电网系统的稳定性以及经济性。
