Abstract

The invention discloses a method for configuring reactive power in a new energy collection area based on big data mining. Voltage operation index; screen out the target plants that need reactive power compensation based on the reactive power and voltage operation index of each plant; calculate and obtain the reactive power voltage sensitivity of each plant; for each plant in the target plant that needs reactive power compensation, Based on the reactive power and voltage operation indicators and reactive power voltage sensitivity of each plant, determine the reactive power compensation equipment and configuration capacity of each plant. The method of the invention does not depend on the topology model of the power grid, can effectively evaluate the reactive power and voltage operation level under the long-term scale of the new energy collection area, and give configuration suggestions in a targeted manner, thereby improving the reactive power and voltage management operation level of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power system operation control, and in particular relates to a method for configuring reactive power in a new energy collection area based on big data mining. Background technique [0002] At present, the scale of new energy development is expanding year by year, and the rapid development of AC / DC hybrid power grids has brought great challenges to the safe operation of power grids. To accurately grasp the operation status of the power grid, analyze the weak links in the operation of the power grid, and reasonably plan the configuration type and capacity of the reactive power compensation equipment are important means to improve the stability and economy of the power grid operation. [0003] Traditional power system analysis is a model-based analysis method whose results depend on the accuracy of network topology and model parameters. It is difficult to analyze whether the configuration of reactive power ...
