Abstract

The invention discloses a micro-grid dispatching method, device and equipment and a storage medium. The micro-grid dispatching method comprises the steps of constructing an operation model corresponding to a micro-grid; wherein the operation model represents operation constraints of a distributed power supply, a power flexible load and an energy storage device in the microgrid; acquiring historical prediction error data of distributed power supply output to determine real probability distribution and empirical probability distribution of the distributed power supply output, and constructing a fuzzy probability distribution set of distributed power supply output uncertainty through a distribution robust optimization method based on the real probability distribution and the empirical probability distribution; and constructing a scheduling model meeting scheduling optimization conditions based on the operation model and the fuzzy probability distribution set, so as to schedule the micro-grid by using an optimized scheduling strategy generated by the scheduling model. The scheduling flexibility and accuracy can be improved, the maximum utilization rate of power is ensured, and meanwhile, the calculation time is saved, so that the scheduling efficiency is improved.

Description

A microgrid scheduling method, device, equipment and storage medium technical field The present invention relates to the technical field of electric power systems, particularly a kind of microgrid scheduling method, device, equipment and storage medium. Background technique [0002] The large-scale penetration of renewable distributed power sources has had an impact on the operation and scheduling of power systems. in this situation Under these circumstances, microgrids have received extensive attention in the industry as an effective method to solve the above problems. MG is a controllable independent The power system, through efficient energy management and coordinated control technology, integrates distributed power sources, energy storage devices and demand-side loads. combined to form a controllable unit. Coordination between distributed power sources, microgrids, energy storage devices and demand-side loads (source-grid-load-storage) Interactions can mitigat...
