Core Tip: Source data of some domestic power storage demonstration projects: public data consolidation 1. The new energy storage market space is expected to exceed 1 trillion by 2030. 1. The scale of the landscape storage market exceeds one trillion. According to the third-party organization, China Energy Looking forward to 2030. In 2020, the installed capacity of new energy and renewable energy will reach about 860 million kilowatts.
Domestic part of the power storage demonstration project
First, the new energy storage market space is expected to exceed trillion by 2030
1. The scale of the wind and light storage market has exceeded one trillion
According to China Energy Outlook 2030 issued by a third party. In 2020, the installed capacity of new energy and renewable energy will reach about 860 million kilowatts, accounting for 42.9% of the total installed capacity; in 2030, the installed capacity will reach 1.44 billion kilowatts, accounting for 60%, contributing 90% between 2020 and 2030. The increase in energy consumption.
The power of the supporting energy storage device is calculated according to 15% of the installed capacity of wind power and photovoltaic. By 2030, the demand for energy storage batteries is expected to reach 850 million kWh, calculated at the price of 1,200 yuan per kWh energy storage system ( lithium battery ). The energy storage market space is expected to reach 1 trillion yuan (RMB).
Second, the global energy storage market forecast
In the next 5-10 years, distributed energy storage, distributed photovoltaic + energy storage, micro-grid and other distribution networks and user-side fields will become hotspots for global energy storage development. Table: Well-known foreign research companies/institutions
Forecast for future energy storage market
1. Five functions of the energy storage battery system
According to the application most according to the energy storage system, it can be summarized as the five functions of the energy storage system: standby power supply, peak clipping, power scheduling, power tracking and suppression of flashing.

2, multiple modes coexist, explore business application mode
At present, domestic energy storage will focus on demonstration applications, major energy storage technology research and industrialization demonstration projects or into national science and technology plans, actively explore energy storage commercial applications in different scenarios, technologies, scales and fields, and standardize relevant standards and testing systems. Prepare for subsequent subsidies for energy storage industry. Figure: Roadmap for the development and application of large-scale applications of energy storage batteries in China
3, lithium battery performance parameters comparison
Lithium-ion battery has the advantages of high energy density, small self-discharge, no memory effect, wide operating temperature range, fast charge and discharge, long service life and no environmental pollution. It is the most feasible technical route in the development of energy storage products.

Third, the analysis of the income situation of large-scale application of energy storage
1. Delay investment in power grid equipment
2. Reduce the network loss of transmission and distribution lines: the load peak load is significantly reduced, and the current in the transmission and distribution lines is reduced, thereby reducing the line and transformer losses.
3. Reduce the required spare capacity: according to the load curve low valley charging, peak discharge, while exercising the role of distributed generation spare capacity
4. Environmental Benefits: Substituting the thermal power unit to complete part of the peak shaving task, indirectly reducing and optimizing the frequent increase and decrease of the thermal power unit.
