Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0044] like figure 1 As shown, a unit coordination control method based on the consistency analysis of regulation performance includes the following steps:

[0045] Step 1: Establish a main control area in the AGC system, implement conventional control of the regional power grid, and establish a model of the main control area.

[0046] The control objective of the above-mentioned main control area is to maintain the frequency of the power grid within the control range, or maintain the power exchange between this control area and other adjacent control areas at a given planned value, or maintain the frequency of the power grid within the control range and maintain the control area The exchange ...

Abstract

The invention discloses a coordinated control method for units based on regulation performance consistency analysis. For the problems that regional power grid frequency-modulation units are various in types and large in regulation performance difference, the regulating characteristic differences of automatic generation control (AGC) regulating units are fully considered, so that a dynamic grouping coordinated control strategy based on regulation performance consistency analysis is provided. Through screening and marshalling the units with relatively consistent regulating characteristics, the regulating tasks of different time scales are assumed according to the difference of the regulation performance, so that the frequency modulation resources of the power grid are effectively utilized; and coordinated and optimal regulation and control of the frequency modulation resources are realized.

Description

technical field [0001] The invention relates to a unit coordination control method based on the consistency analysis of adjustment performance, which belongs to the field of power system control. Background technique [0002] The response of the generator set to its adjustment command determines the control situation of Automatic Generation Control (AGC), and the response of the generator set to its adjustment command depends on its unit type and operation mode. Different types of generating units in the power system have different regulation performance. Hydroelectric units and gas turbines have short response time and fast regulation speed, while coal-fired units have long response time and slow regulation speed. However, the scale of the modern power system continues to develop, and more and more new units are put into operation, which makes the difference between the regulation performance of the generating units become larger and larger. When the system adjustment dema...
