Sineng Electric is proud to announce the successful commissioning of a 6MW/24MWh grid-forming energy storage project in Tibet, China, situated at an average altitude exceeding 4,500 meters. To address the project’s challenging conditions, including high-altitude derating and a requirement for up to three times overloading capacity, Sineng Electric provides a tailored grid- forming energy storage solution. The installation includes three units of Sineng 6.4MW central PCS MV turnkey stations, specifically engineered to optimize performance in such a demanding environment.
As an expansion of the 30MWp solar PV power plant, the energy storage project plays a pivotal role in enhancing the integration of solar energy into the local grid. In addition, it strengthens the resilience of the regional power infrastructure, providing a stable and reliable energy supply for the area’s residents.
During the delivery and commissioning phases, the Sineng team navigated one of the coldest periods of the year in Ngari Prefecture, where heavy snow and rugged mountain terrain posed significant logistical challenges. Despite these harsh conditions, the Sineng team demonstrated exceptional expertise and perseverance, successfully completing the commissioning and system testing, which received high praise from the customer.
This energy storage facility deploys Sineng 6.4MW grid-forming central PCS MV turnkey stations, configured with four 1.6MW central PCS units. These units incorporate VSG technology, along with an advanced control algorithm featuring virtual excitation voltage, virtual impedance/power angle, and inertia damping. The cutting-edge technology offers significant improvements in control logic, response time, and system robustness under grid disturbances.
Sineng Electric continues to lead the way in energy storage technology, with its solutions supporting multiple operational modes, including grid-following, grid- forming, and grid-off configurations. This versatility makes Sineng Electric’s PCS solutions adaptable to a wide range of applications. As the energy landscape continues to evolve, Sineng Electric remains committed to advancing innovation and promoting sustainable energy solutions across the globe.
