The main application scenarios of energy storage on the user side include the improvement of power spontaneous self-use level, peak-valley price arbitrage, capacity cost management, improvement of power reliability and power quality. Under the current policy framework, the benefits of the user-side energy storage power station mainly come from the electricity cost savings brought by the peak-valley price difference.

In the future, under the condition that the market mechanism of distributed renewable energy+energy storage participating in electric auxiliary services is further improved, and the compensation demand response value and other policies are further improved, the benefits of user-side energy storage power stations can also include demand response benefits, deferred upgrade capacity cost benefits, and benefits from participating in the electric auxiliary services market.

1. Positioning requirements

According to the basic information of the project provided by the customer, accurately locate the application scenario of energy storage, whether it is the user side, the grid side or the power supply side;

2. Economic calculation

By selecting economic indicators, the project investment mode, loan or full payment, project operation life, loan interest rate, discount rate and other economic parameters are defined;

3. Project function overlay buff

Taking the user side as an example, the "one power three use matrix" can be used to respectively arrange the functions of peak shaving and valley filling, demand-side response and demand management;

In order to reduce the power cost of users, the peak-shaving and peak-filling capacity of energy storage is mainly used to make it charge at the time of low power consumption and low power consumption at night and discharge at the time of high power consumption and high power consumption during the day. However, on this basis, energy storage can also be used to participate in demand-side response in a specific period of time, and the surplus electricity can be sold to the users who need it, which can not only make full use of electric energy, but also bring some benefits. At the same time, use demand management to reduce the maximum power demand of users and reduce the cost of users' electricity bills.

4. Technical parameters

After the positioning of energy storage scenarios is clear, the economic means are clear, and the combined functions are formed, the system will recommend the types of energy storage, such as lithium-ion batteries, lead-carbon batteries, etc. Users can modify or update the technical and economic parameters of energy storage according to the actual situation;

5. Add wind and light project load parameters

After determining the parameters of energy storage, it is also necessary to understand the actual operation conditions of load, photovoltaic and wind turbine in the energy storage application scenario before further detailed analysis can be carried out;

6. Configuration scheme

After the positioning of energy storage scenarios is clear, the economic means are clear, and the combined functions are formed, the system will recommend the types of energy storage, such as lithium-ion batteries, lead-carbon batteries, etc. Users can modify or update the technical and economic parameters of energy storage according to the actual situation;
