Unified coordination AGC (Automatic Generation Control) control method of interconnected network

Abstract

The invention discloses a coordination AGC (Automatic Generation Control) control method of an interconnected network, comprising the following steps of: providing a unified coordination AGC control method of an interconnected network for rapid development of power generation in China and the requirement of access consumption; making specific technical requirements on the control body, balance manner, adjustment resource, safety restriction and communication transmission of AGC control between the interconnected network areas; providing two specific realizing methods for unified coordination control, i.e., the control mode of total network single machine and the control mode of dispatching equivalence; and describing the area modeling, data uploading, calculating distribution, instruction issuing, and the like in the dispatching coordination control. The invention makes full use of various adjusting resources and consumes the impact triggered by wind power wave in the range of the total network, thereby improving the recovery ability of the electrical network for resisting the wind power fault power deficiency and further effectively exerting the potentiality of AGC coordination control of the total network.

Description

technical field [0001] The invention belongs to the field of electric power system control, and more precisely, the invention relates to an automatic generation control (AGC, Automatic Generation Control) coordinated control method of an interconnected grid considering large-scale wind power access. Background technique [0002] As an important component of clean and renewable energy, wind power has entered a stage of rapid development in my country, and many large-scale wind power bases of 10 million kilowatts and 10 million kilowatts are under construction in some regions rich in wind energy resources. The characteristics of strong randomness, obvious intermittency, and large fluctuation range of wind power output make large-scale wind power grid integration bring new challenges to the operation and control of the interconnected grid. [0003] At present, the active power control mode of my country's regional interconnected grid is mostly a two-level dispatching system, an...
