The method comprises the step of establishing a high energy-consuming load peak regulation model in the new energy power generation mode and the step of conducting analysis of multi-mode and multi-scale high energy-consuming load participation peak regulation on the basis of the established high energy-consuming load peak regulation model in the new energy power generation mode. The high energy-consuming enterprise peak regulation control method used in the new energy power generation mode can overcome the detects that in the prior art, peak regulation pressure is high, tracking capacity is weak and the energy saving effect is poor, thereby having the advantages of being low in peak regulation pressure, strong in tracking capacity and good in energy saving effect.

Description

technical field [0001] The invention relates to the technical field of combining energy-saving technology and power grid peak-shaving technology, and in particular, to a peak-shaving control method for high-load energy enterprises under a new energy power generation mode. Background technique [0002] High-energy-carrying industries are industries in which energy costs account for a relatively high proportion of output value, or energy-intensive industries. The green high-energy-carrying industry is an environmentally-friendly processing industry with advanced technology, high energy utilization, or an environmentally-friendly high-carrying body industry (referring to the high proportion of electricity costs in product output value). Most of the green high-energy-carrying industries are traditional high-energy-carrying industries and basic industries. In terms of scale and technology, they are industries and scales in line with the "Catalogue of Industries, Products and Tech...

Problems solved by technology

[0004] At present, the peak-shaving measures adopted in my country under the new energy power generation mode are mainly on the power supply side. Under the unified dispatch of the dispatching centers of the network provincial companies at all levels, some users have also participated in the peak-shaving and frequency modulation of the new energy power generation grid connection. However, due to the lack of scientific Reasonable peak shaving mode and supporting auxiliary guarantee mechanism, the enthusiasm of users to participate in peak shaving is not high, especially for large-scale wind power generation with abundant power resources and high power consumption needs of high-energy-carrying enterprises, it is urgent to participate in power system regulation However, the research is still in the exploratory stage at present. Compared with the peak-shaving characteristics of conventional power sources, the demand-side load peak-shaving scheduling has the remarkable characteristics of fast response, high economy, and large degree of freedom.

At present, most peak-shaving models do not systematically classify high-energy loads. The peak-shaving method unilaterally considers the peak-shaving capability of the power supply side or the demand side, mainly emphasizing the establishment of a new energy-friendly smart grid and strengthening the peak-shaving capability of the grid. However, the peak-shaving effect of large-capacity and high-energy loads is ignored, which is not conducive to reducing the peak-shaving pressure of the power grid and improving the efficiency of new energy utilization.

On the other hand, the participation of high-energy enterprises in peak regulation provides new ideas for system peak regulation, but the dual randomness of load and new energy also brings new problems to peak regulation: the traditional regulation time span is too long and cannot track load well Random fluctuations with new energy sources are not conducive to power grid energy saving

[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 high peak shaving pressure, weak tracking ability and poor energy saving effect
