Large wind farms in Northwestern China’s Gobi Desert suddenly landing in the doldrums, or AI data centers in Eastern China driving up electricity loads, or millions of electric vehicle owners all deciding to charge up in the evening hours. Such scenarios, which are growing in frequency, increasingly put today’s power grids to the test, forcing them to balance loading capabilities with the ability to dispense power to where it’s needed. That mix is where Shanghai KeLiang Information Technology Co. Ltd., which applied to list in Hong Kong last week, is finding a comfortable place as “invisible guardian” of China's power systems of the future.
Established in Shanghai in 2007, KeLiang provides power system simulation and verification technologies. It uses technologies such as electromagnetic transient simulation, hardware-in-the-loop (HIL) simulation, and frequency-domain stability analysis to build digital models for energy grids and large-scale energy systems, simulating their operating conditions under various extreme scenarios when they are still in the design phase.
