PCS technology frontier, analysis of innovation highlights in 2024
With the profound transformation of the global energy structure and the increasing popularity of renewable energy, the scale of the energy storage market has shown unprecedented growth. This change puts forward more stringent standards for the capacity and voltage level of PCS. With its excellent performance, large-capacity, high-voltage PCS has shown significant advantages in reducing the number of equipment, simplifying the system structure, and reducing overall complexity.
At the same time, they can also greatly improve the operating efficiency of the energy storage system and ensure the stable operation of the system under various working conditions, thus significantly enhancing the stability and reliability of the system. This trend improvement not only perfectly fits the development trend of large-scale energy storage systems, but also lays a solid foundation for the continuous progress and widespread application of energy storage technology, providing a strong guarantee for building a greener, low-carbon, and efficient energy system.
Compared with centralized PCS, string PCS shows better battery cluster management capabilities and system efficiency. Its unique design allows each cluster of batteries to be carefully managed, and the DC side does not need to be connected in parallel, thus effectively avoiding the problem of cell consistency mismatch that may be caused by inter-cluster circulation, and significantly improving the overall performance of the energy storage system and security.
In addition, string PCS also shows significant advantages in operation and maintenance. Its structure is more concise and clear, which greatly reduces operation and maintenance costs and time costs. This series of advantages makes string technology one of the important development trends in the PCS field.
Networked energy storage technology is gradually attracting the deep attention of many PCS manufacturers because of its high technical challenges, high standard requirements in compliance with new national standards, and wide applicability in many application scenarios. As the performance requirements of the power grid for energy storage systems are increasingly increasing, networked PCS will undoubtedly become an important development direction in the field of energy storage technology in the future due to its excellent performance in grid support, black start, frequency and voltage regulation.
Liquid cooling technology further improves the heat dissipation efficiency of the energy storage system through efficient heat conduction and convection mechanisms, and effectively reduces the operating temperature of the system, which is crucial to extending the service life of the energy storage battery and improving the overall safety of the system. As the core component of the liquid-cooled energy storage system, the liquid-cooled PCS not only undertakes the key task of power conversion, but also ensures the stability and reliability of the system under high-load operation through sophisticated liquid cooling system design.
Silicon carbide (SiC) power devices are gradually becoming the preferred material in the PCS field due to their excellent physical properties. Its ultra-fast switching speed greatly reduces energy loss during the switching process, while extremely low conduction loss further improves system efficiency.
At the same time, silicon carbide devices can operate stably at higher temperatures, broadening the operating range of the energy storage system and significantly enhancing the reliability and stability of the system. As silicon carbide technology becomes increasingly mature and production costs continue to decline, more and more PCS manufacturers are beginning to actively introduce silicon carbide power devices in order to take advantage of the fierce market competition.
Intelligent and modular PCS design has gradually become a key solution to adapt to diverse application scenarios. The integration of intelligent technology gives the energy storage system advanced functions such as remote monitoring, fault warning, and intelligent dispatch. This not only greatly improves the operation and maintenance efficiency of the system, but also effectively enhances the stability and reliability of the system, ensuring that the energy storage system continuous and efficient operation.
