Problems solved by technology

[0004] Since some regional power grids contain multiple control areas, the control capabilities and regulation characteristics of each control area are quite different. If the traditional CPS standard is used for evaluation and assessment, the control area with good regulation performance will get better through active support. Good control performance indicators and power compensation, on the one hand, may lead to large fluctuations in the frequency of the interconnected grid, and on the other hand, the control area with poor regulation performance will reduce the enthusiasm for AGC regulation, which is not conducive to the fairness and frequency security of the entire network frequency control

Embodiment 1

[0061] In the prior art, in response to the frequency control requirements of the regional power grid, a regional dispatch control area is generally established in the regional power grid dispatching center (generally called a branch dispatching center, referred to as sub-dispatching), which is mainly responsible for controlling the frequency and tie lines of the power grid. The effect is evaluated. Within the regional power grid, a provincial dispatch center (referred to as provincial dispatch) is established, and a provincial control area is established in the provincial dispatch, such as figure 1 Provincial control area A, provincial control area B, and provincial control area C shown in , the AGC of the provincial control area is used to implement the routine control of the provincial power grid, and the control goal of the provincial control area can be to maintain the power grid If the frequency is within the control range, the exchange power between this control area an...

Abstract

The invention discloses an AGC evaluation and assessment method and device adapted to a multi-region interconnected power grid. The method comprises the steps that control modes of all control zones are acquired; relevant parameters of the control zones are collected, and ACE values of the control zones are calculated; based on the ACE values of the control zones, different assessment index calculation formulas are adopted for the control zones of different control modes to calculate corresponding assessment index values; based on the calculated assessment index values of the control zones, and different evaluation principles are combined to perform control performance evaluation on the control zones. The AGC evaluation and assessment method and device adapted to the multi-region interconnected power grid is applicable to the situation in which a plurality of control zones exist and the control capability and adjustment characteristics are greatly different between the control zones, on the basis of a CPS control performance evaluation standard, by setting different control modes and control performance qualification indexes, the justice and equity of interconnected power grid frequency control performance assessment and evaluation are achieved, and the grid frequency security is ensured.

Description

technical field [0001] The invention belongs to the technical field of power system active power control, and specifically relates to an AGC evaluation and assessment method adapted to multi-area interconnected power grids, and more specifically relates to an AGC with multiple control areas in the regional Internet and with large differences in the characteristics of each control area Evaluation and assessment methods and devices. Background technique [0002] In 1997, the North American Electric Reliability Corporation (NERC) proposed the Control Performance Standard (CPS) for normal conditions and the Disturbance Control Standard (DCS) for disturbance states to control The control performance of each control area of ​​the interconnected grid is evaluated. Because it can make a more objective and fair evaluation of the regional control performance, it plays a good guiding role in the operation and control of the interconnected grid. [0003] The control performance standar...
