Power grid multivariate optimization scheduling method for improving wind power acceptance capability

Abstract

The invention provides a power grid multivariate optimization scheduling method for improving the wind power acceptance capability, which comprises the steps of 1, predicting wind power through a windpower output model, and meanwhile, adjusting spinning reserve of the system; and 2, optimizing the output of each unit, realizing a nuclear power and hydrogen storage assisted joint optimization scheduling method under the condition of taking thermal power as a base load, realizing equivalent peak regulation of nuclear power, and realizing a wind-nuclear-storage-thermal power joint optimization scheduling process. The invention provides a method for improving the wind power acceptance capability through wind-thermal-nuclear storage optimization scheduling. Firstly, a wind power model of windpower uncertain output is established to realize the prediction condition of the wind power output; then a nuclear power peak shaving depth model is established, the nuclear power peak shaving depth is determined, a scheduling model based on joint optimization is established, thermal power, nuclear power and energy storage scheduling is analyzed and determined through an ant colony algorithm, energy transfer and peak load shifting are achieved, and clean energy output is maximized by increasing the utilization amount and utilization rate of clean energy.

Description

technical field [0001] The invention belongs to the technical field of wind power generation accommodation, and in particular relates to a power grid optimization dispatching method for improving wind power capacity. [0002] technical background [0003] With the development of my country's social economy, the demand for energy is increasing year by year, and it has always been supported by the high consumption of petrochemical energy. This has caused the rapid decline in the reserves of non-renewable resources such as coal, oil and natural gas. If we want to achieve sustainable development, we must find renewable energy with large reserves and low pollution. my country's power generation industry mainly uses the combustion of petrochemical energy, but with the development of science and technology, the focus is to put In terms of wind power generation, my country has sufficient wind power resources, which are mainly distributed in the "Three North" regions with abundant wind ...

AI Technical Summary

Problems solved by technology

The random fluctuation and intermittence of wind power make its dispatching method different from that of conventional units, which will inevitably increase the difficulty of formulating power generation plans and dispatching schemes for the power grid, and even affect the safety of power grid operation in severe cases. Therefore, how to make better use of abandoned wind energy , has become a problem that we urgently need to solve
