Multi agent-based power transmission and distribution network and distributed type supply source coordinated control system and method

Abstract

The invention discloses a multi agent-based power transmission and distribution network and distributed type supply source coordinated control system. A power transmission and distribution network dispatching center is connected with a plurality of power distribution networks; the distribution networks are connected with a plurality of micro grids; the micro grids are connected with a plurality of micro grid components; each micro grid component includes a micro power source apparatus; and the coordinated control system includes a micro grid component agent layer which is used for micro power source optimal control, energy storage devices and controllable loads, a micro grid agent layer used for micro grid-level power grid dispatching operation control, a power distribution agent layer used for medium-voltage network and low-voltage network operation control, and a power transmission network agent layer used for the operation control of a whole power grid . According to the multi agent-based power transmission and distribution network and distributed type supply source coordinated control system of the invention, a power transmission and distribution system comprising distributed power sources is divided into agents with different functions; and through control on each agent and interaction between the agents, hierarchical coordinated control on the power transmission and distribution system comprising the large-scale distributed power sources can be realized.

Description

technical field [0001] The invention relates to the technical field of power system operation control, in particular to a multi-agent transmission and distribution network and distributed power supply coordination control system. Background technique [0002] With the increasingly prominent energy and environmental issues, distributed renewable energy power generation has gained more and more attention and application. A large number of distributed power sources are connected to the power grid, which brings challenges to the operation and control of the power system: with the further increase of the penetration rate of distributed power sources, the scale and complexity of the control variables of the power system are greatly increased. The bottleneck of control is becoming more and more obvious, and centralized control will be difficult to meet the operation and control requirements of power systems with large-scale distributed power sources; how to coordinate and control m...

A large number of distributed power sources are connected to the power grid, which brings challenges to the operation and control of the power system: with the further increase of the penetration rate of distributed power sources, the scale and complexity of the control variables of the power system are greatly increased. The bottleneck of control is becoming more and more obvious, and centralized control will be difficult to meet the operation and control requirements of power systems with large-scale distributed power sources; how to coordinate and control many geographically dispersed distributed power sources to ensure the stable operation of power systems has become a problem for power system workers important question
