The 15th China International Energy Storage Conference (2025CIES) was grandly held at the Hangzhou International Expo Center, where Guangzhou Zhiguang Electric Technology Co., Ltd. (hereinafter referred to as "Zhiguang Electric Technology") actively participated.

As an industry leader in high-power power electronics, Zhiguang Electric Technology is driving innovation at this critical juncture of the energy transition. The company unveiled a range of industry-leading solutions, injecting new momentum into sustainable energy development. Among its showcased innovations were the Grid-Forming Mobile Renewable Energy & Energy Storage Grid Connection Testing Device and the High-Voltage Dynamic Reactive Power Compensation Device, both of which garnered significant market attention for their advanced performance.

1.  Zhiguang High-Voltage Dynamic Reactive Power Compensation Device

The Zhiguang High-Voltage Dynamic Reactive Power Compensation Device achieves reactive power conversion through high-frequency switching of power electronic components, demonstrating unparalleled advantages over traditional reactive power compensation equipment in terms of compensation effectiveness, power density, and operational efficiency. It represents the optimal solution for comprehensive power quality management, effectively enhancing transient voltage stability, suppressing bus voltage flicker, compensating unbalanced currents, filtering harmonics, and improving power factors.

Notably, Zhiguang launched the fourth-generation 6-10kV prefabricated container-type Dynamic Reactive Power Compensation Device last year. With its compact structure, high performance, and versatile functionality, it provides cost-effective power quality solutions for industries such as petrochemicals, distributed renewable energy, coal and metallurgy, electrified railways, and urban infrastructure.

2. Zhiguang Mobile Renewable Energy & Energy Storage Grid Connection Testing Device

Designed to address the unique challenges of renewable energy and energy storage grid integration, Zhiguang Electric Technology’s Mobile Testing Device surpasses traditional testing equipment in fault simulation, grid simulation architecture, and data analysis capabilities. Its key technical indicators have reached international leading standards.

This device is applicable to grid-side, generation-side, and user-side energy storage and renewable power plants, supporting system commissioning, grid connection performance testing, and operational evaluations. It accommodates various energy storage technologies—including cascaded, string, and centralized configurations—as well as lithium-ion, flow, lead-acid, and flywheel energy storage systems. The system meets the grid connection testing requirements for both grid-following and grid-forming technologies, effectively identifying grid integration defects and faults to ensure the safe and stable integration of renewable energy.

Zhiguang’s Mobile Testing Device has successfully conducted over 100 grid performance tests and compliance assessments across Guangdong, Hunan, Henan, Hebei, Fujian, Yunnan, Chongqing, Shandong, and Ningxia, significantly contributing to the secure and economic operation of the power system.
