Household Small Solar Energy Storage Device

This paper proposes a household small solar energy storage device,the device was designed to ease,auxiliary by clean energy power generation power grid operation pressure,reduce the cost of family,society electricity for power grid peak work environment cut and increase household electricity reliability,convenience,at the same time can supplement the power supply in time and then into a portable power supply equipment.Topic in paper for small pv nimh energy storage system built on the basis of the power source of the energy storage system,has the energy active dispatch control and wireless communication functions and features,but the current system in the case of a solar power during the day can not meet the needs of family day normal electricity,so the subject put forward a kind of based on the user of electricity and solar power generation forecasting of electricity smart scheduling algorithm,by using the time series model,based on user history of electricity used to forecast the future of electricity;By using BP neural network algorithm,through the history of solar power and its corresponding weather forecast the future of solar power generation,the system according to two prediction values of power dispatching,to decide when to use grid power supply or batteries for charging,when to use solar energy for charging or power supply,to optimize for solar power or electricity grid of the electric energy and electric energy in battery pack and reasonable use.By setting up a Windows PC program to complete solar power generation with the user power consumption forecasting and into intelligent scheduling algorithm for power value must charge,down a machine energy storage device sends commands to low energy storage device control in AC/DC power grid electricity price stage complete charging process;At the same time,the upper computer monitors the battery pack status,load status and solar power status of the energy storage device.This project has increased the application of smart home on the basis of the new energy generation technology,and has improved the practical application of the household at the same time.
