A peak-shaving method for large-scale new energy grid-connected power generation

Abstract

The invention discloses a peak shaving method for large-scale new energy grid-connected power generation. The method comprises the steps of establishing a large-scale new energy grid-connected peak shaving model and analyzing a peak shaving notch based on the established large-scale new energy grid-connected peak shaving model. By means of the peak shaving method for large-scale new energy grid-connected power generation, the defects of large investment, low new energy utilization rate, high power grid loss and the like in the prior art can be overcome, and the advantages of small investment, high new energy utilization rate and low power grid loss can be achieved.

Description

technical field [0001] The invention relates to the technical field of the combination of new energy and electric power technology, in particular to a method for peak regulation of large-scale new energy grid-connected power generation. Background technique [0002] Since the 21st century, with the development of social economy and rising energy demand, countries around the world have increased the use of coal, oil, and natural gas. Due to limited reserves and increasing exploitation, these resources will inevitably be exhausted. The global energy crisis and the destruction of the ecological environment have become issues related to human survival and development. How to save and use energy and improve its utilization efficiency has become the focus of attention of all countries, and the energy problem in the power industry is particularly prominent. As a national basic industry, the electric power industry is the main direct utilization industry of primary energy in my coun...

Under the unified dispatch of dispatching centers of grid and provincial companies at all levels, some users also participate in the peak-shaving and frequency-regulation of new energy power generation grid connection. The enthusiasm is not high, especially for large-scale wind power generation with rich power resources and high power consumption needs of high-energy-carrying enterprises. There is an urgent need to conduct research on user participation in power system peak regulation. However, this research is still in the exploratory stage and there are no relevant research results direct reports of

At present, the solutions for most models mainly take measures from the power supply side, such as expanding power supply capacity or forcing load adjustment to maintain the stability of grid load operation. These peak-shaving methods unilaterally consider the peak-shaving capacity of the power supply side, and mainly emphasize the establishment of new energy friendly Type smart grid strengthens the peak-shaving capability of the power grid, while ignoring the peak-shaving effect of the power consumption side, and the large investment and high geographical requirements are not conducive to improving the efficiency of new energy utilization, reducing grid network losses, and improving the level of power conservation

[0005] In the process of realizing the present invention, the inventor found that there are at least some defects in the prior art, such as large investment, low utilization rate of new energy sources, and large power grid loss.
