Research on Fine Modeling of Several Household High Power Load

该文基于家用负荷的物理模型、用户的使用习惯和用户的舒适度要求,提出了家用大功率负荷的精细化建模方法,该方法可应用于家庭能量管理系统,具有良好的应用前景。首先,建立考虑电热水器负荷的精细化热力学动态模型,考虑气温、墙体等因素的空调房间的精细化热力学动态模型和电动汽车负荷的精细化储能模型;然后,建立这三种负荷的精细化控制模型,通过自定义家庭算例将不同个性化的精细化参数模型对比分析。MATLAB仿真结果表明,该文建立的精细化动态模型能够准确描述用户的用电规律,对用户积极参与到电力系统需求响应中去起到促进作用。

This article proposes a refined modeling method for high-power household loads based on the physical model of household loads,user usage habits,and user comfort requirements.This method can be applied to household energy management systems and has good application prospects.Firstly,establish a refined thermodynamic dynamic model considering the load of electric water heaters,a refined thermodynamic dynamic model considering factors such as temperature and walls in air-conditioned rooms,and a refined energy storage model for electric vehicle loads.Then,establish refined control models for these three types of loads,and compare and analyze different personalized refined parameter models through custom household examples.The MATLAB simulation results show that the refined dynamic model established in this article can accurately describe the electricity consumption patterns of users,and play a promoting role in actively participating in power system demand response.
