Problems solved by technology

[0026] The present invention aims at the problem that the traditional power regulation and distribution scheme cannot satisfy the development of the current power system, and proposes a dynamic optimal distribution method for power regulation with a dead zone. The implementation of this method can not only greatly reduce the number of actions of the unit, but also Guarantee the pass rate of CPS

Embodiment Construction

[0061] Automatic generation control (AGC) is an indispensable tool for power grid dispatching and operation, and has become an essential technical means to ensure safe, high-quality, and economical operation of the power grid. The load frequency control software of the power grid dispatching center collects the frequency of the power grid, the power flow of the tie line, and the time difference of the system clock through the data acquisition and monitoring system (SCADA), calculates the regional control deviation ACE of the control area, and obtains a smooth ACE after filtering. Then the ACE gets the regulated power through the AGC controller P r ,like figure 1 Shown is a schematic diagram of the dynamic optimal allocation process of the AGC system adjustment power. The present invention is aimed at adjusting the power P r After the dynamic optimization distribution is carried out, the adjustment command is sent to each unit on the power grid.

Abstract

The invention relates to a regulation power dynamic optimization and distribution method with a dead-zone. A dead zone value is related to the scale and allowed frequency of a regional power grid; regulation entering a dead zone scope is considered as in a quasi-stable state; the output of regulation power is unchanged; the regulation power is given to a regulated automatic generation control (AGC) unit according to an economic distribution principle; therefore, the yield of a control performance standard is ensured under the condition that the operation frequency of the unit is reduced; the regulation power is distributed according to the speed of the unit in a regulation region; and the rapidity of frequency regulation is ensured.

Description

technical field [0001] The invention relates to a large-scale power system grid frequency control technology, in particular to a dynamic optimal distribution method of regulated power with a dead zone. Background technique [0002] The North American Electric Reliability Council (NERC) launched the Control Performance Standard CPS (Control Performance Standard) in 1996. Since it was officially implemented in 1998, this standard has been evaluated based on the contribution of the control area to the frequency of the entire grid, and the power quality and safe and stable operation of the entire grid have become the control goals, so that the interests of most areas are guaranteed. Its content is as follows: [0003] 1. CPS1 [0004] The CPS1 standard means that within an assessment period (such as one year), the regional control deviation ACE of the control area should meet the requirements of the following formula: [0005] [0006] In the formula ACE i —— Control ar...
