Abstract

The invention discloses a configuration method for primary frequency modulation spinning reserve capacity after new energy grid connection. The method is characterized by comprising the following steps of: collecting the related data of a target power grid, establishing the simulation model of the target power grid, and determining various typical operation modes and calculation conditions of thetarget power grid; determining the spinning reserve configuration schemes of the target power grid under each typical operation mode according to the actual operation conditions and safe and stable operation requirements of the target power grid; checking whether the data of the adjusted target power grid meet the safe and stable operation requirements or not; and calculating a primary frequency modulation spinning reserve configuration security domain so as to determine the configuration of the primary frequency modulation spinning reserve capacity after the new energy grid connection. The method is simple and rapid. With the method adopted, the simulation calculation precision of the spinning reserve capacity optimization of the power grid is guaranteed; the actual limitations of the stable operation of the power grid are considered; actual guidance suggestions are provided for the operation of a power system and planners; and the improvement of the safety and stability of the operation of the power system can be facilitated.

Description

technical field [0001] This application relates to the field of power system security, stability and control, and specifically relates to a method for configuring a primary frequency modulation rotation reserve capacity after new energy grid-connected. Background technique [0002] Since the beginning of the 21st century, my country is in a period of rapid development of modernization construction, and energy demand shows a rigid growth characteristic. The supply is far below the potential demand, and there is huge pressure on energy conservation and emission reduction. With the proposal of the global energy Internet strategic concept, the "four AC and four direct" UHV projects of the national air pollution prevention and control action plan have been fully launched, the national energy development is facing a major strategic transformation, and the power grid is ushering in new development opportunities. The construction of a new energy pattern dominated by clean energy and...
