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

Abstract

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.

Description

Technical field [0001] The present invention belongs to the field of micro-grid energy management, and in particular, the present invention relates to a micro-grid reference recent market extensive system optimization operation method. Background technique [0002] In the context of a new round of power system reform, the main size of participating in electricity market transactions is gradually expanding. The real-time node electricity price has gradually replaced the current catalog electricity price system, which will bring a huge impact on the control strategy of the micro-grid energy management system. Originally for micro-grid sources, lottery, coordination, economically optimized dispatching strategies will lose its role. Traditional microglinal optimization strategy research is mainly focused on coordination between distributed power supply, energy storage device, load, energy conversion, and protection equipment, that is, in a running cycle, to operate its priority to sc...
