Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] The multi-party energy supply structure of a typical industrial park is as follows: figure 1 shown. In the park, there is a large-scale combined heat and power (CHP) system, which uses natural gas as its main fuel. The high-temperature steam generated in the combustion chamber can be used to generate electricity through micro and small power equipment, and the generated electricity can be sold to Power grid company or directly supply industrial users in the park. The medium and low temperature exhaust heat generated in the power generation process is recycled by waste heat boiler equipment and sold to industrial users in the park in the form of medium-grade hot steam (170-550°C), which is used as the main heat source for the user's industrial production.

[0053] The park management center is responsible for the interaction a...

Abstract

The invention discloses an industrial user thermal demand response method based on multi-energy complementation; according to an industrial park multi-party energy supply architecture with a combinedheat and power supply system CHP, a heat demand response interaction mechanism is formulated, and industrial typical equipment is subjected to independent modeling; by taking satisfaction of peak shaving requirement of a park region management center and consideration of operation economical efficiency of the industrial user as an optimization objective, a thermal demand response mode is established under cold and hot electric power balance constraint, equipment physical constraint and demand response constraint; and the model is optimized and solved to obtain an industrial user thermal demandresponse strategy. According to the method, the requirements of the user for cold, hot and electric energy are contained in a demand response range, and the method is started from the perspective ofthe industrial user, a reasonable demand response strategy is provided, so that the electric power vacancy is effectively relieved, and the electricity utilization safety and stability of the industrial park are improved; and compared with a traditional demand response strategy, the response modes are diversified, the user side loss is lower, the scheduling cost of a power grid company is less, and win-win between a power grid company and a user side can be achieved.

Description

technical field [0001] The invention relates to a thermal demand response method for industrial users based on multi-energy complementarity, and belongs to the field of comprehensive energy and electric power demand response. Background technique [0002] Demand response (demand response, DR) is an effective means to integrate the response potential of the user-side power grid. Through the "two-way interaction" between the demand side and the power grid, it can alleviate the tension and contradictions of power supply and balance the fluctuations brought by intermittent renewable energy to the power grid, so as to effectively Improve the security and stability of power grid operation. The industrial park has a stable industrial load and a high level of automation, and has great potential for demand response. However, the current research results seldom consider the influence between multiple energy demands. In fact, industrial users have different needs for multi-energy sou...
