For intelligent power grid power supply management, establish the link by data center, dc, intelligent meter, intelligent user terminals, intelligent load control device, communication network consisting of low voltage power grid management system of intelligent effect. Offered to increase energy saving as the core of the intelligent power grid to low voltage side power management methods; Create the intelligent measurement, the load forecast and energy storage management technology as the foundation, the electric communication and local area wireless communication technology for support and combine load control technology of power management technology system, and formed a power grid and client power two-way information flow and interactive load control energy efficiency management mechanism.

Through this system, on the one hand, the user can real-time remote monitoring household appliances energy consumption and electric power company provide information services such as the price of electricity, early warning information, and can control appliances to break a state, according to electric power usage patterns, improve the optimal power efficiency, save electricity expenses; On the other hand, the electric company can remote acquisition user electricity energy consumption, according to the above analysis, information and predict load conditions, and intelligent user terminals to release electricity price, service information, and to power through intelligent load control device directly control household appliances, power consumption peak period in remote selectively shut off the power appliances in a balanced load, so as to form the power grid and client power two-way information flow and interactive load control energy efficiency management mechanism, realize the power management and load balance.
