Research on Control Strategy of Smart Home Efficiency Management System with Household Distributed Photovoltaic Power Station

介绍了带有蓄电池的分布式光伏发电系统对电网削峰、填谷的作用。设计了基于ZigBee技术的家庭电器通信网络实现对每一个电器远程控制、监测和采集用电信息。根据采集到的用电信息建立能效管理数学模型,得出每个电器最优的用电时刻,并根据得到的用电计划自动控制电器开关。在Matlab环境下建立模型仿真,验证家庭能效管理系统带来的经济效益。

This paper introduced the distributed PV generation system with a storage battery and how it contributes to the public grid in load shifting. A household appliances network on the base of ZigBee technology was designed to realize remote control and monitoring as well as electricity consumption information gathering. In this system, home appliances are divided into different levels of delay tolerance and based on their operation information, an energy management mathematic model is built, dividing the time of a day into 480 3-minute-long units and combined with actual time-of-use electricity price in Shanghai, to get the economically optimum operation plan by traverse. According to the optimum operation plan, all the appliances＇ operations are controlled by the system automatically. In the last part the economic profit was calculated by simulating the mathematic model in Matlab environment.
