Energy Storage PCS power innovation, challenges and breakthroughs

With the continuous innovation of energy storage technology, PCS (energy storage converter) as the"Heart" of energy storage system, its power directly affects the overall performance and application range of energy storage system. As the market for cell capacity continues to iterate, PCS power demand will increase. The development of more powerful PCS has also become a top priority for PCS manufacturers, and a challenge for them.

Challenges in power enhancement for energy storage PCS

01. Heat dissipation problem

With the increase of PCS power, the internal power devices will generate a lot of heat during operation. If the heat can not be dissipated in time and effectively, the temperature of the device will be too high, which will affect its performance and life, and even cause safety problems. For example, under the condition of high power continuous operation, the reliability of power devices may decrease by about 50% for every 10 °C increase in temperature, and the heat dissipation design has become a major bottleneck for power improvement.

02 electromagnetic interference and electromagnetic compatibility

High-power PCS in the work, will produce strong electromagnetic interference. These interferences will not only affect the stable operation of its own system, but also may cause adverse effects on the surrounding electronic equipment. How to increase the power of PCS while ensuring that they meet strict electromagnetic compatibility standards and reduce interference with other devices is a problem that engineers must overcome.

Complexity of 03 control algorithm

As the power increases, PCS become exponentially more difficult to control. In order to achieve efficient and stable energy conversion, more accurate and complex control algorithms are needed. This requires that the control algorithm can monitor and adjust multiple parameters such as current, voltage and frequency in real time, and adapt to different working conditions and load changes, which puts forward extremely high requirements for the technical ability of the research and development team.

04 device performance limits

High power operation puts forward higher standards for the performance of power devices such as voltage and current resistance. At present, some power devices on the market are difficult to meet the needs of continuous high-power operation. Finding or developing high-performance power devices has become one of the key constraints to improve the power of PCS.

Application advantages of 03450kw PCS

The launch of INPOWER's 450kW PCS brings significant advantages to energy storage projects. In large-scale industrial and commercial energy storage projects, high-power PCS can be managed one cluster at a time to avoid the“Cask effect” caused by uneven SOC between clusters and improve the response speed and efficiency of the energy storage system. An industrial and commercial energy storage project with multiple 450KW PCS, for example, generates more economic benefits per year than traditional low-power PCS under the peak-valley tariff arbitrage scenario.

In the grid side energy storage project, INPOWER smart storage 450 kw PCS can quickly respond to power grid dispatching instructions, realize peak load shifting and frequency regulation through charging and discharging regulation, and improve the stability and reliability of the power grid. And INPOWER smart storage 450kW-PCS fusion high voltage box, reduce the integration cost at the same time can realize the integration of AC and DC container, reduce the system cost and area, improve the overall economy of the project.

Increasing the power of energy-storage PCS has been difficult, but companies like INPOWER are making breakthroughs thanks to innovation. The successful development and application of INPOWER's 450KW PCS not only demonstrates the industry's technological progress, but also injects new impetus into the development of the energy storage industry. In the future, as the technology continues to iterate, there is reason to believe that the continued innovation of INPOWER PCS will contribute more to a cleaner, more efficient and more stable energy system.
