Distributed control system of multi-agent power distribution network and distributed control method thereof

Abstract

The invention provides a distributed control system of a multi-agent power distribution network and a distributed control method thereof and relates to the power transmission and distribution technology field. Based on a distributed control strategy, under conditions that application cost is low and a control method is simple and easy, a power grid voltage is controlled not to be out-of-limit and an absorptive capability of a power grid to renewable energy grid connection is improved. The distributed control system comprises a regulation and control unit, a plurality of voltage acquisition units, a transformer control agent and a plurality of renewable energy control agents. The plurality of voltage acquisition units are connected to an on-load voltage regulating transformer and nodes where a plurality of renewable energy power generator groups are located in a one-to-one correspondence mode. The plurality of renewable energy control agents are connected to the plurality of renewable energy power generator groups in the one-to-one correspondence mode. The renewable energy control agents are connected to the regulation and control unit and the voltage acquisition units. The transformer control agent is connected to the regulation and control unit, the on-load voltage regulating transformer and the voltage acquisition units. The distributed control system is used for adjusting an operation state of a power grid.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to a distributed control system and a distributed control method of a distribution network based on multi-agents. Background technique [0002] In recent years, more than 80% of the world's energy consumption relies on fossil energy such as coal, oil, and natural gas. Excessive consumption of fossil energy has led to a large amount of greenhouse gas emissions, which in turn has led to a series of problems such as energy shortage, climate change, and environmental pollution. . At present, in order to reduce the consumption of fossil energy and achieve sustainable energy development, vigorously developing renewable energy such as wind energy and solar energy has become a common choice of all countries. [0003] However, with more and more renewable energy connected to the grid and the increasing load brought by electric vehicles and electric heating, it ha...

Problems solved by technology

[0004] In the prior art, in order to solve the above problems, the distribution network usually adopts a central dispatching cooperative control system, but using the above control system, on the one hand, it is necessary to add acquisition and sensor devices at each node in the power grid, and the data processing capacity is huge. This leads to high application costs; on the other hand, multiple renewable energy sources in the grid are under the unified control of central dispatching instructions. When new renewable energy sources are connected to the grid, the control strategy needs to be readjusted, which makes the application process very cumbersome

Therefore, the existing central scheduling cooperative control system has low applicability and is not easy to promote
