EMA to modify energy grid with two major digital projects

Singapore will improve its energy infrastructure with its first Grid Digital Twin.

The Energy Market Authority (EMA) revealed the development of Singapore’s first Grid Digital Twin and Distributed Energy Resource Management System (DERMS) for the country’s energy transition, access to clean energy, and improvement of its energy grid infrastructure.

With notable industry partners, EMA ensured the digital transition of Singapore’s energy grid infrastructure for the next few years.

Launched in 2021, the Grid Digital Twin seeks to enhance Singapore’s grid resilience, reliable support, and uniform deployment of cleaner energy sources. The development is composed of two key models, Digital Asset Twin and Digital Network Twin, both virtual replicas of the grid network and its infrastructural assets.

The Grid Digital Twin, currently, has seen significant progress in research and development. The Asset Twin has been purposed to conduct concise decisions for prioritised and prompt renewal and maintenance of grid assets, capable of being applied towards 18,000 transformers across SP’s 12,000 substations.

EMA developed the Digital Network Twin with partners like A*STAR’s Institute of High-Performance Computing for the development of the Singapore Integrated Transport and Energy Model to identify electric vehicles as part of the national grid. It is currently in the next stage of translational research and development, with a planned deployment by 2025.

The agency also commenced the improvement of Distributed Energy Resources, like solar generation systems, battery energy storage systems, and electric vehicles. The DERMS allows the monitoring and control of network operators with real-time data, optimised by the connections of small-scale DERs.

Through these projects, Singapore’s energy transition remains resilient and reliable for the deployment of cleaner energy sources.
