An optimization control method and system for an electric heat pump-heat and power combined system

Abstract

The present invention provides an optimization control method and system for an electric heat pump-heat and power combined system, which relates to the technical field of energy operation, can regard each unit as a different subject, and regulate and control with the goal of maximizing the self-interest of each subject, not only can Satisfying the load demand of heat and power users can also make the main body of each unit satisfied with its income to the greatest extent; the method includes S1, establishing the composition structure framework of the electric heat pump-heat and power combined system, and establishing the output model of each unit; S2, establishing the power The revenue function model of each unit in the heat pump-combined heat and power system; S3. Establish a non-cooperative game model for the electric heat pump-combined heat and power system; S4. Use the particle swarm optimization algorithm to solve the game model to obtain the optimal heat and power dispatching plan for each unit. The technical scheme provided by the invention is suitable for the regulation and control process of the electric heat pump-heat and power combined system.

Description

【Technical field】 [0001] The invention relates to the technical field of energy operation, in particular to an optimization control method and system for an electric heat pump-heat and power combined system. 【Background technique】 [0002] In the international environment where the energy structure is undergoing profound changes, the global energy transformation is advancing in depth, and the development and utilization of clean energy such as wind power and photovoltaics has also been vigorously developed, which is the key to achieving sustainable development. Under the global trend of energy transformation, the combined heat and power system that combines heat and power units with wind power and photovoltaic power generation is an effective form of energy development and utilization. However, during the heating period, the combined heat and power unit produces a large amount of power, and the operation mode of the cogeneration unit "determines electricity by heat" greatly ...

Problems solved by technology

However, these methods do not take into account that each unit may belong to different subjects, and the decision-making behaviors of different subjects affect each other, that is, there may be conflicts between the overall optimization of the system and the optimal profit pursued by each subject. It may not be the optimal solution for each subject, which will cause each subject to deviate from the optimization plan and seek other solutions to obtain higher returns
