The residential energy storage system uses the solar power generation device on the roof， and the low-cost power source of the social power supply system. The abundant power is stored in the energy storage system for use in peak hours. It can not only be used as emergency power supply, but also save power expenditure for families.
Mtigate power system related problems like ever-increasing load demand, power loss,voltage deviation and need for power system up-gradation as integration of electric vehicles(EVs) increases load while charging. sell excess energy stored to the utility grid during times of high demand. optimize the size of PV/BESS system to minimize power consumption and the system active power loss.
Provide users with a peak-valley electricity price arbitrage mode and stable power quality management; have been successfully applied in large-scale industrial, commercial and residential areas, and been expanded to emerging scenarios such as base stations, UPS backup power, off-grid and island/isolate systems，etc.
Restore a stable power grid, optimize the power output curve, reduce solar and wind curtailment, provide system inertia and the functions of frequency and peak modulation, increase the proportion of renewable energy in total power generation, and optimize the energy structure.
Provide smart load management for power transmission and distribution, and modulate frequency and peak in time according to power grid loads. has the functions of capacity increasing and expansion, backup power supply, etc. It can adopt more renewable energy in power transmission and distribution to ensure the safety, stability, efficiency and low-cost operation of the grid.
