Description

technical field [0001] The invention relates to the field of new energy power generation, in particular to a grid load modeling method for improving wind power absorptive capacity. Background technique [0002] With the sustained and rapid development of my country's economy, the gradual depletion of fossil fuels, and the increasing environmental pollution and greenhouse effect, based on the sustainable development strategy, the Chinese government attaches great importance to the development and utilization of new energy, and regards the development and utilization of new energy as a way to control the atmosphere. Pollution, adjustment of energy structure and transformation of economic development are major measures, and wind power and photovoltaic power generation are regarded as one of the main ways of new energy development and utilization. [0003] Due to the scarcity of wind energy resources, the energy density of time and space is low, and it cannot be enriched, transpo...

Problems solved by technology

[0003] Due to the scarcity of wind energy resources, the energy density of time and space is low, and it cannot be enriched, transported and stored, and must be directly converted into electric energy, which brings about the intermittency and volatility of wind power, as well as the unschedulability of time and space in power generation. Insufficient peak-shaving capacity of the power grid in the rapidly developing "Three Norths" region and the limitation of transmission sections in some areas have increased the difficulty of balancing the active power of the power system, and the phenomenon of wind abandonment in such areas is serious
