Abstract

The invention discloses a scheduling method and device based on a microgrid. The method comprises the following steps of: constructing a battery operation model based on the electric quantity cost andthe electric quantity consumption of a battery in the microgrid; constructing a unit combination model of the microgrid according to the battery operation model; determining an operation scheme withthe minimum operation cost of the microgrid in a preset time period based on the unit combination model; and scheduling the microgrid according to the operation scheme. The method and the device solvethe technical problem that in the prior art, the microgrid is required to be analyzed on the basis of a large number of scenes, so that the calculation amount of microgrid scheduling is large.

Description

technical field [0001] The present invention relates to the field of microgrid scheduling, in particular to a microgrid-based scheduling method and device. Background technique [0002] Micro-Grid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, compliance, monitoring and protection devices, etc. At present, the scheduling of microgrids is mainly based on scenario-based stochastic planning, that is, scheduling of microgrids is based on deterministic models under Monte Carlo simulation scenarios. With the increase of the number of investigation scenarios, the calculation amount in the above method also increases exponentially, thus increasing the operating burden of the computer system. Although the use of different techniques can reduce the number of survey scenarios, thereby reducing the operating burden of the computer system, but this method may ignore some low-probability...
