Abstract

The invention provides an interconnected power grid automatic power generation control performance evaluation method under concentrated wind power access. The method comprises the following steps: determining the wind power fluctuation regulation responsibility sharing coefficient K<+ / -> of control areas of an interconnected power grid in the next scheduling period; determining the total wind power control error WCE of the interconnected power grid in the automatic power generation control period; determining the power grid frequency deviation Delta(f) and the area control error ACEi in each control period; and judging whether the control performance of each control area is qualified. The method is used for solving the problem that the automatic power generation control performance evaluation criteria is unfair to AGC control performance evaluation of local control areas with concentrated wind power and the problem of wind curtailment of rich wind power caused by poor regulation ability of a local power grid.

Description

technical field [0001] The invention relates to a method in the field of automatic power generation control of an interconnected power grid, in particular to a performance evaluation method for automatic power generation control of an interconnected power grid adapted to large-scale wind power centralized grid connection. Background technique [0002] The interconnected grid refers to the grid formed by the interconnection of inter-provincial grids, independent provincial grids, and large hydrothermal power bases. At present, in the interconnected power grids of various countries, the active power control performance of automatic generation control (AGC) in each local power grid operation control area is evaluated and regulated by its performance evaluation standards. For example, in the 1960s, North America has been using the A1 and A2 control performance standards (referred to as A standards) issued by the North American Electric Reliability Council (NERC). The operation ...
