SINGAPORE — Hitachi ABB Power Grids and Nanyang Technological University, Singapore (NTU Singapore), will work together to advance developments in Solid State Transformer (SST) technology.
The project is led by the Energy Research Institute at NTU (ERI@N), and is supported by the National Research Foundation, Singapore (NRF).
The project is part of the Singapore Government’s flagship Energy Grid 2.0 initiative aimed at shaping the next-generation grid system and transforming how energy is managed by consolidating multiple energy sources into a single intelligent network that is more efficient, sustainable and resilient.
Solid state transformers (SST) incorporate power semiconductor components, control circuits and high-frequency transformers, offering bi-directional power flow control, harmonics reduction, and other benefits. They allow conversion from AC to DC, DC to AC and also DC to DC on different voltage levels. They are designed to support power system transformation towards more flexible AC and DC mixed system configurations, facilitating the integration of renewable energy sources close to DC loads.
NTU’s Senior Vice President (Research) Professor Lam Khin Yong, said, “The Solid State Transformers (SST) are multifunctional and will allow users flexible control on the amount of power that is distributed to networks. Lam continued, “By doing away with multiple separate equipment required by current conventional transformers, we also save on land-use, making the SST an attractive solution for a more efficient electricity grid.”
Dr Yeoh Lean Weng, Senior Director for Urban Solutions and Sustainability at NRF, said, “The partnership between NTU and Hitachi ABB Power Grids is one of many examples that demonstrates the international recognition our local institutions receive for scientific excellence.” He continued, “Singapore is committed to supporting cutting edge research that not only meets our national needs, but through wider partnerships, advance the benefits beyond our shores.”
