Recently, Electricite Du Cambodge (EDC) has successfully completed a series of tests including regional power grid black start and off-grid/grid-connected operation, using the 100 MW/200 MWh GS12 grid-forming energy storage power station as the startup power source.
All key functional verifications were accomplished in one go, covering black start, regional grid restoration, isolated grid operation, start-up and grid connection of hydro and thermal power units, as well as switching operation between off-grid and grid-connected modes with the main power grid. The whole process ran steadily, fully achieving the preset test objectives.
NR Electric provided an all-round grid-forming integrated solution equipped with full sets of core equipment such as grid-forming PCS, EMS and PMS, together with system simulation test support for this project.
During the test, the grid-forming energy storage system maintained full-process grid-forming voltage source characteristics. Multiple large-capacity main transformer impact tests of 75 MW and 100 MW were carried out. A total of 182.8 kilometers of 230kV high-voltage transmission lines were put into operation, restoring the operation of four 230kV substations and 40 MW regional load. It also successfully supported the start-up and grid connection of large-capacity hydropower and thermal power units at the terminal, forming a stably operated regional power grid integrating power sources, loads and energy storage.
Meanwhile, three synchronous grid-connection tests and two off-grid disconnection tests between the energy storage system and the main grid were completed. The system maintained stable voltage and frequency support throughout the whole process.
NR Electric’s NR-ISGrid ideal synchronous power source grid-forming energy storage technology plays a vital role in improving power grid resilience, enhancing system stability and supporting rapid grid restoration.

This regional power grid black start test fully verifies the maturity and advancement of NR Electric’s NR-ISGrid ideal synchronous power source grid-forming technology.
NR Electric will continue to drive innovation and engineering application of grid-forming energy storage, and contribute more NR solutions to the global new generation power systems.
