Embodiment Construction

[0079] A power demand response method based on the discontinuous production process and storage capacity of a cement enterprise of the present invention comprises the following steps:

[0080] In step S1, the electricity load in the cement enterprise is divided into interruptible load and non-interruptible load, and the processes and equipment involving the interruptible load are counted.

[0081] In step S11, the electricity load in the cement enterprise is divided into interruptible load and uninterruptible load, wherein the uninterruptible load refers to the electric equipment that operates continuously throughout the day or within a fixed period of time, and the interruptible load refers to the electricity consumption time. The segment can be disconnected from the electrical equipment.

[0082] Step S12, count the processes and equipment that can interrupt the load, and the processes mainly include raw material preparation, raw meal preparation, clinker calcination and cem...

Abstract

The invention discloses a power demand response method based on a discontinuous production process and storage capacity of a cement enterprise, and the method aims at the discontinuous production process in the cement industry and adds a material storage link. Time allocation is performed on the production process of the cement enterprise cluster and the renewable energy power abandoning curve of the renewable energy power generator or the excess power generation curve of the power grid, so that the cement enterprise cluster can consume more energy when the new energy power abandoning is serious or the power generation of the power grid is excess; the power demand response method based on the discontinuous production process and the storage capacity of the cement enterprise is provided, the dependence of a power grid on pumped storage and energy storage batteries is effectively reduced, and the timely consumption capacity of a future novel power system for solving the problems of intermittency, volatility and the like caused by large-scale new energy grid connection is enhanced; and meanwhile, a high-energy-consumption enterprise is assisted to save the operation cost, the utilization rate of energy and resources is improved, and source-load interaction and synergistic interaction of a novel power system and cement enterprise cluster demand side response are achieved.

Description

technical field [0001] The invention belongs to the technical field of power grid demand side response, and in particular relates to a power demand response method based on the discontinuous production process and storage capacity of cement enterprises. Background technique [0002] The cement industry is one of the traditional high-energy-consuming industries. Facing the dual pressures of the shortage of fossil energy and the national dual-carbon goal, cement enterprises are in urgent need of energy transformation and adjustment. At present, the energy-saving and consumption-reducing technologies in the cement industry mainly focus on the improvement of production process, the improvement of product raw materials, the reuse of waste and the energy-saving technology of specific equipment, and the energy-saving potential of time allocation of renewable energy and discontinuous cement processes is not realized. SUMMARY OF THE INVENTION [0003] The purpose of the present inv...
