Problems solved by technology

However, the demand for distributed energy to participate in the dispatching operation of the distribution network brings great challenges to the coordinated control of the active distribution network.
[0003] At present, the distribution network does not have effective coordinated control technology at the distribution network level for the large-scale access of distributed energy. From a systematic point of view, combine distributed power generation, loads, energy storage devices, and control devi

Abstract

The invention discloses a region coordinated control system based on an active power distribution network. The power distribution network comprises a coordinated control region. The control system comprises source network coordinated controllers and a region coordinated controller, wherein the source network coordinated controllers are used for controlling the power output of distributed energy sources, monitoring the running states of the distributed energy sources and uploading the state information to the region coordinated controller, and the distributed energy sources are respectively provided with one source network coordinated controller; and the region coordinated controller is connected with all the source network coordinated controllers in the coordinated control region and used for receiving the states of the distributed energy sources, uploaded by all the source network coordinated controllers, and issuing control commands to the controllable distributed energy sources according to the states so as to dispatch the power of the corresponding distributed energy sources. The region coordinated control system realizes the efficient utilization of renewable energy sources in a self-government region and realizes an optimum region control target through the mutual coordination of the region coordinated controller and the source network coordinated controllers.

Description

technical field [0001] The present invention relates to the field of intelligent distribution network for the coordinated control of the coordinated control area under the active distribution network with large-scale access to distributed energy. The invention proposes a coordinated control method for the coordinated control area of ​​the active distribution network. Background technique [0002] The active distribution network, with its active control mechanism introduced in the distribution network, is an effective solution for the future intelligent distribution network to realize the active management of a large number of distributed energy sources. However, the demand for distributed energy to participate in the dispatching operation of the distribution network brings great challenges to the coordinated control of the active distribution network. [0003] At present, the distribution network does not have effective coordinated control technology at the distribution netw...
