Abstract
The invention relates to a micro-grid economic dispatching control method. By considering virtual real-time electricity price, a distributed power supply has certain positive peak regulating characteristic for a power grid, and when an energy storage system in a micro-grid participates in peak and off peak load regulation, peak and valley areas of a load are used as boundary points of switching of working modes of a battery. In a grid-connected operating mode of the micro-grid and a large power grid, when the current electricity price is at a virtual electricity price peak, output of each distributed power supply is regulated by using the electrical energy of a minimum dissipative mains supply as a target; and when the current electricity price is at a virtual electricity price valley, output of each distributed power supply is regulated by using full charge of the energy storage system as a target. In a micro-grid isolated island operating mode, output of each distributed power supply is regulated by using meeting of load requirements and safe and stable operation of the system as targets. With the adoption of the method, the peak and valley performance of the power grid is improved, the power supply reliability is improved, and clean energy generation and step energy utilization are ensured by combined dispatching of multiple constraint conditions and multiple control targets.
