Customer side peak shaving solution


Summary:
Energy storage can provide users with a complete set of energy services in the power consumption side. Through energy storage, peak shaving and valley filling can be realized, the power consumption scheme can be optimized, the demand side response can be made in response to the power grid, and it can also be used as backup power supply in emergency. The solution of energy storage at the power consumption side improves the power quality of users, reduces the power consumption cost, ensures the stable operation of the power grid and improves the energy utilization efficiency.

Characteristic:
Reduce electricity consumption and demand;
Optimize the power utilization scheme and improve the power quality;
Management of power consumption and energy to improve energy utilization rate;
The energy storage side is reduced to respond to the demand side;
It can be used as backup power supply to deal with emergency;
Energy storage products are standardized and scalable;
Delay power system upgrading

Usage scenarios:
It is suitable for commercial buildings, industrial parks and other users with large electricity load, especially in areas with large peak valley price difference.

Profit mode:
Peak valley price difference Arbitrage: the load is charged in the low price period, and discharged in the peak period of electricity price, so as to obtain the profit from price difference.
Reduce the basic tariff: reduce the peak load. When the basic tariff is measured according to the maximum demand (yuan / kW), the basic tariff can be reduced
Demand side response subsidy: according to different local policies, users can obtain subsidies according to the reduced load power to reduce the user side capacity increase cost: by reducing the maximum load power, the investment in power transformation and distribution equipment is reduced

Generation side ancillary service (AGC) solution

Summary:
China's power resources and regional economic distribution is not balanced, power grid load fluctuations, peak load regulation resources are scarce. With the large-scale heating transformation of thermal power units, the proportion of heating units increases, and the deep peak shaving of thermal power units endangers their own and power grid safety. And with the large-scale integration of renewable energy, the impact on grid operation and scheduling will be increasingly obvious. According to the actual situation of the power plant and its participation in the auxiliary service, the advanced energy storage system of a certain scale is configured, which can significantly increase the auxiliary service capacity of the power plant.

Characteristic:
