Abstract

The invention discloses a load scheduling method, device and equipment of energy storage equipment and a storage medium. The method comprises the following steps: acquiring a load scheduling demand of a power grid and scheduling application information sent by registered energy storage equipment; determining a scheduling instruction corresponding to the registered energy storage equipment according to the load scheduling demand and the scheduling application information; and sending the scheduling instruction to the registered energy storage device, so that the energy storage device completes load scheduling according to the instruction of the scheduling instruction. According to the technical scheme, energy storage equipment such as electric vehicles can serve as distributed energy storage equipment in the power grid, the effects of stable output power and small random fluctuation can be achieved without being restrained by natural conditions, scheduling is conducted according to load scheduling demand changes in the power grid, and on the premise that use of a user is not affected, the method can flexibly participate in centralized dispatching of power grid loads, fully dispatches and uses potential energy storage equipment in a power grid, and improves the safety and stability of the power grid.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electric power dispatching, and in particular, to a load dispatching method, device, device and storage medium of an energy storage device. Background technique [0002] As new energy becomes the main energy source and gradually replaces thermal power generation, the power grid needs to absorb more and more new energy power generation, and the peak-to-valley difference in load is getting bigger and bigger. Power dispatching is facing new challenges. The safety and security of power grid operation Stability is under serious threat. [0003] In response to the above problems, the concepts of distributed power generation and distributed energy storage are introduced into the power grid to participate in the operation of the power market and power grid. However, due to the limitation of natural conditions, distributed power generation has strong randomness and volatility in its outp...
