Abstract

The invention provides a cement enterprise load power adjusting method, which comprises the following steps of: substituting power utilization data and production data of a cement enterprise into a pre-constructed adjustable load potential model to obtain a plurality of power regulation modes and durations under the various power adjustment modes; calculating the operation cost of the equipment in each power adjustment mode based on the duration time and the power utilization cost in each power adjustment mode; and adjusting the power of the load of the cement enterprise in a power adjusting mode with the minimum operation cost, wherein the adjustable load potential model is constructed by starting a cement mill, interrupting a raw mill and / or interrupting a power adjustment mode of the cement mill to obtain different load interruption durations. The method and system are beneficial for guiding off-peak production of cement enterprises, improving production benefits, helping a power grid to stabilize a load curve and improving the safety guarantee level of the power grid.

Description

technical field [0001] The invention belongs to the field of adjustable load potential and load adjustment economic cost analysis, and the invention relates to a power adjustment method and system for cement enterprise load. Background technique [0002] The continuous development of smart grid and the gradual implementation of demand response have promoted the attention of power users to their own adjustable load resources. China's industrial electricity consumption accounts for a large proportion of the whole society's electricity consumption, reaching about 70%. Compared with commercial and residential users, industrial users have the advantages of large response capacity, stable load and high level of automation, and have the ability to develop intelligent electricity consumption. A sound foundation of management is the most important demand-side resource in the power system. The cement industry is a large energy consumer among industrial users. Taking China as an examp...
