Suoying Electric Ouyang Chao: Innovation and practice of energy storage PCS electrical system in large-scale energy storage
On April 11, 2024, the 12th International Energy Storage Exhibition was officially launched. During the same period, forums on energy storage technology, products, applications and other related topics were held one after another. Ouyang Chao, general manager of Soying Electric Energy Storage Division, brought the latest The launched ES series of new liquid-cooled energy storage converters were unveiled at the “Energy Storage Design and Solutions Forum”, and the theme of “Innovation and Practice of Energy Storage PCS Electrical Systems in Large-Scale Energy Storage” was shared in depth with industry colleagues present. .
The demand for energy storage in new power systems The demand for energy storage in new power systems
According to relevant statistics, in the past 10 years, the cumulative installed capacity of renewable energy (wind power and photovoltaic) has grown from 92.41 million kilowatts in 2013 to 1.05 billion kilowatts in 2023, and the proportion of installed electricity capacity has increased from 7.3% to 36%. Under the dual-carbon policy, wind power, photovoltaics and energy storage complement each other during the development of new power systems. Ouyang Chao said: “Double-high power system, firstly, the proportion of new energy is getting higher and higher, and secondly, power electronics. This causes the power change rate of the power system to be more than an order of magnitude faster than before, which puts forward necessary requirements for new energy storage : Security is the foundation, stability is the guarantee, and economy is an important value indicator.”
Large-scale energy storage is the key support of the new power system. Modeled energy storage is the key to the new power system.
Through large-scale deployment of energy storage equipment, the storage and release of electric energy can be achieved to balance the difference between power supply and demand and improve the stability and reliability of the power system. At the same time, the increase in battery capacity, the decline in market prices, the market demand for high power, high cost performance, high safety and reliability, and the requirements of harsh natural environments such as sand, moisture, and smoke indicate that high-power and high-density liquid-cooled energy storage converters The device is a reliable choice for the energy storage market. Ouyang Chao said: “Energy storage must be used, and we must make energy storage generate its real value, so the new ES series liquid-cooled energy storage converter brought this time can build more confidence in the energy storage market.”
ES-5000K liquid-cooled energy storage converter: It has the ability to build a network, allowing the unit to maintain continuous, stable and reliable operation under a weak power grid. It has passed tests such as fast measurement, fast response, high and low zero voltage ride through, and VSG.
ES-5000S energy storage converter and boost cabin: It is integrated with energy storage converter, transformer, water cooler, high-voltage switch and control equipment, etc. It has strong environmental adaptability and can cope with harsh natural conditions such as sand, moisture, and smoke. environment.
ES-215K liquid-cooled string converter: refined charge and discharge management of cluster-level batteries, greatly improving battery performance, highly integrated modular design, plug and play.
ES-5000M string converter and booster cabin: Inverter, transformer, water cooler, high-voltage switch and other equipment are integrated, the power module is cut out separately, and the quick-plug interface facilitates maintenance and replacement.
In terms of practice, Soying Electric has successfully participated in the construction of multiple large-scale energy storage projects and accumulated rich experience. Mr. Ouyang Chao mentioned that as early as 2011, Soying Electric participated in the construction of the National Wind and Solar Storage and Transmission Demonstration Project and achieved the verification of core technologies such as multi-machine parallel connection, providing strong technical support for the implementation of subsequent large-scale energy storage projects. . It is worth mentioning that Soying Electric has made unique achievements in the field of battery testing systems, especially the 1600V high-frequency and high-voltage professional energy storage testing system. It is a recently launched special equipment for energy storage systems. It has strong flexibility and powerful functions. It has great market share. It has a high share and is highly recognized by the industry.
To sum up, Soying Electric’s innovation and practice in the field of energy storage PCS electrical systems have provided strong technical support and solutions for the development of large-scale energy storage. In the future, with the continuous advancement of technology and the continuous expansion of the market, Soying Electric is expected to achieve more brilliant achievements in the field of energy storage.
