In this paper

a smart home system based on ZigBee technology is designed.The system includes home network

home server and mobile terminal.The program is simple

effective and scalable.This paper studies the home efficiency management system based on distributed photovoltaic power station and energy storage system.Through the establishment of the objective function of minimizing the household electricity cost

the control strategy of home efficiency management is given

based on time-of-use electricity price.By deciding the charge and discharge power of energy storage battery and working time of shiftable loads

the optimal utilization of home loads can be realized

in order to improve operation economy and maximize economic benefits.It can also play the role of peak load shifting.Finally

combined with home appliances of a home user

the proposed algorithm is tested.The simulation results show that the algorithm can effectively save the household electricity cost

and demonstrate that the algorithm is effective and feasible.
