[0003] Winter is the season with the largest amount of wind power generation. However, in this season, the heating unit undertakes the heating task of ensuring people's livelihood, and its ability to participate in peak regulation is significantly weakened. A large number of wind power connected to the grid poses a challenge to the peak regulation capability of the grid.
[0004] At present, the peak regulation method of heating units is single, limited to participate in the peak regulation of the power grid in the lower load range, and the major power grids have almost raised their mediation capabilities to a very high level, relying only on the traditional mediation method of reducing the load of conventional power plants Unable to meet the ever-increasing demand for wind power, heating units basically cannot participate in peak regulation in winter
[0005] The traditional peak shaving method is far from meeting the needs of the power grid for winter peak shaving, and reducing load peak shaving is not conducive to improving the economy of energy utilization

Embodiment Construction
[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0023] figure 1 Schematic diagram of the operating device for peak regulation of heating units, figure 1 The heat source in the system is a thermal power plant. During normal operation, the heating network water of the thermal power plant is supplied to the heat user through the heating network water pipe, and the heating network return water is returned to the thermal power plant through the heating network return pipe. When peak shaving is required, peak-staggered heat storage is carried out through the heat accumulator. When the heat supply peak comes, use the re...

The invention provides a wind power access method and a system based on a heat supply unit participating power grid peak shaving. The method includes obtaining heat supply information of the heat supply unit, and generating top and bottom limitation information of heat supply amount according to the heat supply amount information; generating a heat supply season peak shaving curve according to the top and bottom limitation information of the heat supply amount, and determining a peak valley time value according to the peak shaving curve; storing heat at peak shifting according to the peak valley time value; and deeply shaving peak on the condition of pure condensation, and accessing large scale wind power to a power grid. According to the method and the system, total load capacity of a heat supply season thermal power unit participating power grid peak shaving is increased, and new energy resources can be accessed to the power grid as many as possible.
Description
technical field [0001] The invention relates to power grid peak regulation technology, in particular to a wind power access method and system based on the participation of heating units in power grid peak regulation. Background technique [0002] Wind power is one of the most widely recognized new and clean energy sources today, and wind farms have been built on a large scale in China. [0003] Winter is the season with the largest amount of wind power generation. However, in this season, the heating unit undertakes the heating task of ensuring people's livelihood, and its ability to participate in peak regulation is significantly weakened. A large number of wind power connected to the grid poses a challenge to the peak regulation capability of the grid. [0004] At present, the peak regulation method of heating units is single, limited to participate in the peak regulation of the power grid in the lower load range, and the major power grids have almost raised their mediatio...
