Since its establishment in June 2018, Xi'an Golden stone Electric Technology Co., Ltd. (referred to as GSSTES) has gone through a tumultuous year. Not only has it launched intelligent energy storage system solutions, but also has independently developed a full range of centralized control chain energy storage converters (PCS) and optical storage integrated machines. The products are mainly used in domestic projects in Shandong, Jiangsu, Xizang, Taiwan, and other countries abroad, such as Switzerland, South Africa, Germany, Australia, and have received unanimous praise.
At the 2019 SNEC exhibition site, the reception room prepared by GSSTES was not enough, and some customers who came from afar could only sit on the seats at the front desk and wait in line for negotiations.
Guo Lei, General Manager of GSSTES, said in an interview with International Energy Network reporters, 'With the continuous development of intelligent technology and the refined personalized needs of customers, the intelligence of energy storage systems is constantly improving. This is the demand of customers, the inevitable progress of technology, and also the historical choice. GSSTES is taking advantage of the situation'.
Although the current energy storage industry in China is still a barren land with scattered sparks, the wave of commercialization is still lurking in the shadows. But Jingshi Technology has come up with a quick move, combining efforts on the grid side, user side, and power supply side, and has also established a strong research and development team with excellent technical strength. This is a rare heavy investment in the domestic energy storage market, where the vast majority of companies are still hesitant and waiting for changes.
International Energy Network: How do you view energy storage policies and industry technology trends?
Guo Lei: The arrival of the first year of energy storage, as well as the related industry policies such as the "Guiding Opinions on Promoting Energy Storage Technology and Industrial Development," marks the arrival of spring in the energy storage industry. At present, energy storage projects are mainly applied in related fields such as power generation, grid side, user side, microgrid, communication energy storage, emergency power supply, etc. Experts predict that energy storage will gradually transition to a rapid development stage in the next decade, mainly applied in areas such as peak shaving and valley filling, grid side electrochemical energy storage, new energy generation, clean energy related applications, and distributed energy storage.
Although the energy storage industry has not yet exploded, various energy storage technologies have been widely applied in industrial, commercial, and power station demonstration projects, demonstrating the advantages of energy storage projects while gradually exposing some problems, especially electrochemical energy storage technology, which still has a considerable gap from the development goals of low cost, long life, high safety, and easy management.
Various manufacturers have relevant technologies for monitoring and managing energy storage projects, but with the continuous development of intelligent technology and the refined personalized needs of customers, the intelligence of energy storage systems is constantly improving. This is the customer's demand, inevitable technological progress, and also a historical choice.
International Energy Network: What preparations has Jingshi Technology made in the development of smart energy storage?
Guo Lei: Firstly, GSSTES people have devoted themselves to analyzing the current trend of energy storage technology, new energy and energy storage policies, and industry development trends. Based on the existing energy storage technology, they have proposed the concept of smart energy storage, integrating intelligent control and interconnected sharing into energy storage solutions. They use vivid language to metaphorically describe smart energy storage, just like equipping energy storage projects with the strongest brain. The energy storage industry will enter a new era of smart energy storage from now on.
Furthermore, in terms of smart energy storage layout, GSSTES has a complete set of BCU, PCU, SCU, and EMS control technologies. BCU is responsible for battery and DC/DC data acquisition and processing; PCU collects AC/DC unit data and uploads it to SCU, and performs logical control according to SCU instructions. SCU communicates with BCU, PCU, electricity meters and other devices to achieve data processing, strategic control and human-computer interaction; At the same time, an EMS system is also integrated internally.
In addition, the term "smart energy storage" has been recognized by the industry, and well-known energy storage companies in the industry are mainly divided into: energy storage product suppliers with unique technological routes and obvious competitive advantages in terms of cost; Export suppliers of energy storage products or production equipment with an international perspective; Energy storage operation and maintenance service providers who master core application technologies and cooperate with insurance companies to provide energy storage leasing services; The energy storage system companies under the power grid company have successively laid out the field of smart energy storage and have begun to develop strategies for smart energy storage.
The era of intelligent energy storage will inevitably become the mainstream direction of energy storage industry development.
The future development of energy storage cannot be separated from the strong combination of intelligence and energy storage. The level of intelligence will become the benchmark for measuring the development of the energy storage industry. GSSTES will spare no effort to continuously innovate and break through in technology, and contribute to the vigorous development of the era of intelligent energy storage.
International Energy Network: What are the advantages of centralized control chain solutions that have a great impact on the industry?
Guo Lei: Compared with traditional energy storage solutions, the centralized control chain intelligent energy storage solution proposed by Jingshi Technology achieves refined battery management, flexible configuration, efficient and safe power conversion, and a comprehensive control system with multiple layers of protection to ensure system safety.
The advantages of centralized control chain can be explained from three aspects: centralization, control, and chain. Each battery is independently controlled for precise control, achieving one-to-one management, reducing series parallel mismatch of batteries, and improving the number of times batteries can be recycled. Thoroughly solve the problems of traditional energy storage power stations with multiple batteries connected in series, large number of PCS connected batteries, difficult management and control, and single battery failures causing the entire battery stack to be disconnected from the system
The centralized control chain solution achieves fine management, intelligent control, interconnection and sharing, and interconnectivity; By gaining recognition from users and peers, we have solved the pain points of difficult battery management, low charging efficiency, and project control in customer energy storage projects.
