Sineng Electric has announced the commissioning of a 6MW/24MWh grid-forming energy storage project in Tibet, situated at an average altitude exceeding 4,500 metres. To address the project’s challenging conditions, including high-altitude derating and a requirement for up to three times overloading capacity, the installation includes three units of the company’s 6.4MW central PCS MV turnkey stations, specifically engineered to optimize performance in such a demanding environment.
As an expansion of a 30MWp solar PV power plant, the 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.
The 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.
