A Home Energy Management Algorithm Based on Building Thermodynamic Model

Abstract

The invention discloses a household energy management algorithm based on a building thermodynamic model. The algorithm comprises that an indoor and outdoor heat transfer model of a building is established; and thermodynamic modules of main household power utilization loads as an air conditioner, a water heater and a refrigerator are established. Different factors including the heat exchange rate, the sun heat radiation intensity and the material thermal capacity are taken into consideration in the models, change of electricity price of the electrical network in the optimization process is considered to achieve the economically optimal target on the premise that the resident power utilization requirement is met, the power consumption of users in the peak period is transferred to the valley period in the aspect of the electrical network, the utilization rate of power utilization equipment is improved, the pressure of peak load regulation of the electrical network is reduced, and a win-win effect is achieved.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a home energy management algorithm based on a building thermodynamic model. Background technique [0002] In my country, due to the use of a large number of consumer electronic products and electrical appliances, the energy consumption in the home and office fields is increasing dramatically. In recent years, the domestic electricity consumption of Chinese residents has increased at a rate of tens of billions of kilowatt-hours per year. Because so far, the "green environment-friendly society" we want to create is still in its initial stage. Saving energy consumption mainly depends on people forming good habits, such as turning off unused electric lights, increasing / decreasing the temperature setting of air conditioners by 1°C, etc. However, the energy saved by the above method is limited, and the damage to people's quality of life also makes it difficult to be popularized on...
