Embodiment Construction

[0064] Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:

[0065] figure 1 It is a specific flow chart of the reactive power optimization control method of the regional power grid based on the multi-agent technology provided by the present invention.

[0066] figure 2 The wiring diagram of the regional distribution network powered by the 220kV substation of the embodiment is given.

[0067] The method comprises the steps of:

[0068] Step 1: The substation, as a control-level intelligent body, sends out voltage and reactive power optimization demand signals according to the control needs;

[0069] Step 2: After the coordination level agent receives the voltage and reactive power optimization demand signal, it sends an optimization control demand signal to each control level agent;

[0070] Step 3: Each control-level agent determines whether to request to participate in optimal contr...

Abstract

The invention discloses a regional power grid voltage reactive power optimization control method. According to the regional power grid voltage reactive power optimization control method, multi-agent technology is applied to a power grid reactive power optimization control decision model, relationships between a plurality of targets during reactive power optimization are changed by changing the scoring weight, and then the maintainability and the expansibility of a regional power grid online reactive power optimization control system are enhanced; the regional power grid reactive power optimization control adopts a multi-agent technological model, a multi-agent technology based reactive power optimization control system architecture is provided, a large amount of burdensome rules in expert system suboptimum control is avoided, the relationships between the plurality of targets during the reactive power optimization are changed by simply changing the weight of the scoring weight, and the maintainability and the expansibility of the system are enhanced.

Description

technical field [0001] The present invention is a reactive power optimization control system architecture using multi-agent technology in the online reactive power optimization control of the regional power grid to realize the robustness, maintainability and scalability of the online reactive power optimization control system of the regional power grid. The invention belongs to the technical field of safe and reliable operation control of electric power system. Background technique [0002] The online reactive power optimization control of the regional power grid optimizes the power flow distribution of the power grid by adjusting the status of the transformer on-load tap-changer and reactive power compensation device in real time, so as to achieve the purpose of bus voltage and hub node power factor qualified. It is a system with equality and inequality constraints. Nonlinear mixed integer programming problems. At present, various models and algorithms used for reactive po...
