Technical FAQs 4

What is the largest grid-forming energy storage station in China?

This marks the completion and operation of the largest grid-forming energy storage station in China. The photo shows the energy storage station supporting the Ningdong Composite Photovoltaic Base Project. This energy storage station is one of the first batch of projects supporting the 100 GW large-scale wind and photovoltaic bases nationwide.

What is China's first 'wind-solar-thermal-storage integration' project?

(Photo by Xu Ke/People's Daily Online) China's first "wind-solar-thermal-storage integration" ultra-high voltage (UHV) project, the Longdong-Shandong ±800 kilovolt direct current (DC) transmission project, was put into operation on May 8.

What is the Longdong-Shandong project?

The Longdong-Shandong project also marks the debut of China's standardized technology for UHV DC transmission at ±800 kilovolts and 8 million kilowatts. Several similar projects are now underway across China.

What is the integration rate of wind and solar power?

The integration rates of wind and solar power are 64.37 % and 77.25 %, respectively, which represent an increase of 30.71 % and 25.98 % over the MOPSO algorithm. The system's total clean energy supply reaches 94.1 %, offering a novel approach for the storage and utilization of clean energy. 1. Introduction
