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

Abstract

The invention provides an optimized control method and system for an electric heat pump- combined heat and power system, relates to the technical field of energy operation. The method can take each unit as a different main body, and performs control by taking benefit maximization of each main body as a target, thereby meeting load requirements of combined heat and power users, and satisfying the each unit main body with the revenue to the maximum extent. The method comprises the following steps: S1, establishing a composition structure framework of the electric heat pump-combined heat and power system, and establishing an output model of each unit; S2, establishing a revenue function model of each unit in the electric heat pump-combined heat and power system; S3, establishing a non-cooperative gaming model of the electric heat pump-combined heat and power system; and S4, solving the gaming model by particle swarm optimization to obtain a combined heat and power scheduling optimizationscheme of each unit. The technical scheme provided by the invention is suitable for the control process of the electric heat pump-combined heat and power system.

Description

[Technical field] [0001] The present invention relates to the field of energy operations, and more particularly to an optimized regulation method and system of an electrothermal pump-thermoelectric combined system. 【Background technique】 [0002] In an international environment in which the energy structure has a deep change, the global energy transformation is in-depth, and the development and utilization of clean energy such as wind power, photovoltaic, is also a key to achieving sustainable development. Under the global trend of energy transformation, the thermoelectric integrated system combined with wind power and photovoltaic power generation is an effective energy development and utilization. However, in the heating period, the thermoelectric gauge is great, and the thermoelectric network "heat-saving" operation is greatly reduced by the adjustment capabilities of the thermoelectric gauge, limiting the flexibility of the power system, resulting in abandonment The wind is m...
