Embodiment Construction

[0039] The basic idea of ​​the distributed energy storage aggregation participating in the coordinated operation of the power grid under the multi-energy interconnection proposed by the present invention is: for the energy storage monomer aggregation and multiple energy sources to jointly participate in the grid-connected peak-shaving operation, by combining multiple energy storage units Groups are aggregated into groups, using stage-by-stage optimization control and existing dispatching system control to achieve the purpose of large-scale distributed energy storage aggregation and multi-energy interconnection to participate in power grid peak-shaving control.

[0040] Such as Figure 1-5 Shown, the present invention comprises the following steps:

[0041] Step 1), establish a distributed energy storage aggregation to participate in the overall control and operation framework of power grid peak regulation;

[0042] (1) Establish a multi-objective optimization model for distri...

Abstract

The invention relates to a coordinated operation method of a distributed energy storage aggregation participated power grid, in particular to a distributed energy storage aggregation participated power grid peak regulation strategy under the multi-energy internet. The access capability of renewable energy sources in the power distribution network is improved, the economic benefits of the power grid and users are increased, and powerful support is provided for development of the intelligent power distribution network. The method specifically comprises the following steps: step 1, establishing a distributed energy storage aggregation participated power grid peak regulation overall control operation framework; step 2, establishing a distributed energy storage aggregation and multi-energy cooperative operation multi-objective optimization model; and step 3, performing staged optimization solution on the distributed energy storage aggregation and multi-energy cooperative operation multi-objective optimization model based on a heuristic intelligent algorithm.

Description

technical field [0001] The present invention relates to a coordinated operation method for distributed energy storage aggregation to participate in a power grid, in particular to a strategy for distributed energy storage aggregation to participate in power grid peak regulation under a multi-energy Internet. Background technique [0002] In the future, the high proportion of distributed energy access will have an increasingly significant impact on the power grid. The organic integration of multiple energy storage systems to achieve multi-energy complementary energy storage systems will be the main form of future energy storage systems used in power grids. Distributed energy storage, as a key technology for new grid and energy interconnection, can improve system operation stability, improve power quality, improve grid regulation flexibility and power supply reliability, realize load peak load reduction, participate in system demand response, and peak shaving Wait. However, th...
