It is reported that China Energy Smart Energy Technology (Shanghai) Co., Ltd. has completed the project planning and design of the 720 megawatt hour energy storage power station in Gansu, which has entered the land use approval stage.

In August of this year, the company announced the launch of the project in Shanghai. Due to its huge size, the project is also known as a super engineering project and has been widely concerned in the industry since its announcement.

Zhou Xiwei, a specially appointed researcher at the National Energy Distributed Energy Technology Research and Development Center, introduced that the 720 megawatt hour energy storage website in Gansu belongs to a large-scale energy storage system in the network domain, and all use lithium iron phosphate batteries.

The following is the keynote speech "Case Analysis of Large scale Energy Storage Power Station Project in Gansu" made by Lu Feng, Deputy Director of Project Management Department and Chief Design Engineer of Power Generation Design Branch of Northwest Electric Power Design Institute Co., Ltd. of China Power Engineering Consulting Group, at the recent high-level seminar on energy storage and application.

Speech Record

Lu Feng: Good morning everyone! It is a great honor to share and exchange ideas with all the experts at the conference. The case I am sharing today is the "Gansu Large Scale Energy Storage Power Station Project". After our institute has completed the feasibility study report, Gansu has applied to the National Energy Administration for a demonstration project.

The project is located in the Jiuquan area of Jiayuguan, Gansu, which is the area with the most severe wind and solar energy abandonment. It is the middle position of the network channel from Xinjiang to the northwest. Due to the limitations of the transmission capacity of the channel, wind and solar energy abandonment is very tense in the afternoon. This project belongs to the multi energy complementary energy storage demonstration project, which solves the problem of new energy consumption.

This project has a relatively large installed capacity, with a planned capacity of 1.5GW and a first phase of 720MWH. The report I shared is divided into six parts, the first being the background of project construction.

From the perspective of the scale of the energy storage market, including the application scenarios, Director Zheng of Tsinghua University just introduced it quite clearly. I won't go further. From both the international and domestic markets, lithium-ion batteries account for a relatively large proportion of electrochemical energy storage, and their development has been relatively rapid in the past two years.

This is a price prediction, as the domestic energy storage industry, after nearly a decade of development, is currently in a crucial transitional period from demonstration applications to commercial applications.

In addition, from the perspective of batteries, after years of technological progress, especially from last year to this year, stimulated by policies, including demand, our domestic manufacturers have also shown high investment enthusiasm, and the production is now relatively large, further driving down the price of batteries.

From our perspective, the cost of mainstream energy storage such as lithium-ion batteries is predicted to drop to about 1000 to 1200 (per watt hour) by 2020. The decline in battery cost also provides a solid foundation for large-scale commercial applications of energy storage.

So in the past two years, especially last year, a large number of energy storage related and electrochemical energy storage projects have been initiated or put into operation in China.

In the field of renewable energy grid connection, there are demonstration projects for photovoltaic energy storage on the Qinghai DC side, hybrid energy storage projects for wind power plants and electric heating in Jilin Province, and auxiliary services.

On the user side, there are more. In economically developed regions such as Jiangsu, Beijing, and Guangdong, intensive commercial applications have been carried out using peak valley price differences, reaching 121MW in 2017. From a policy perspective, these two experts have more interpretations of policies, so I won't go into detail.

I would like to emphasize the important supporting points of the project. One is the "Notice on Promoting the Participation of Electric Energy Storage in the Pilot Work of the" Three North "Area Electric Power Auxiliary Service Compensation Mechanism" issued by the National Energy Administration on June 7, 2016, which is the State Energy Regulatory Commission's 2016 and 164. The market compliance of independent energy storage power stations has been established, and there is a requirement for the scale of independent energy storage power stations, with a charging power of over 10MW and a duration of over 4 hours.

From the perspective of profit model, there is a supporting point. The amount of electricity stored and discharged is equivalent to the power generation capacity of the power plant. By settling according to the relevant contract electricity price of the power plant, I can settle according to the original electricity price contract of that plant. This is also a profit point recently adopted for this project.

In addition, from the perspective of local policies, many provinces in Northeast China and Fujian Province have implemented auxiliary services. In 2018, the market operation scale of implementing auxiliary services was expanded.

The second part is an overview of the power system. The project is located in Jiajiu Power Grid, which accounts for 70% of new energy, so the pressure on frequency regulation and peak shaving is particularly high. According to data, the wind curtailment rate of Jiajiu Power Grid in 2017 was 34% to 39%. We have a prediction and conducted an analysis based on six modes, which means that the entire Jiajiu Power Grid has surplus, especially at 13pm in winter, the surplus of electricity reached 6150 to 7040 kilowatts, with a photovoltaic system on the left, On the right is the storage curve of wind power. These two curves fit the above and correspond to the electricity consumption curve of the Jiajiu region
