Clean Energy Capability Portfolio | Grid Transformation

Large-scale Autonomous

Microgrid Operated at
Constant Frequency

Technology that offers a method for designing autonomous microgrids in the scale of several megawatts using renewable energy and storage . Conventional synchronous generators and renewable energy based generation are harmonised using zonalisation approaches , allowing systems to handle large load changes . Integration with large power systems is also possible through paralleled solid-state transformers .

Competitive Advantage

• Improved power quality in large-scale autonomous microgrids
• Heavier loads ’ switch-in and switch-off
• Significant reduction in using fossil fuels for synchronous generators
• Affordable and convenient energy storage

Impact

• Alleviate pressure from fossil fuel depletion
• Reverse air pollution in some countries that rely heavily on less fine coal-fired generation
• Allow more inhabitants and factory zones to be built with self-sufficient power supply
• Successful Applications
• Laboratory proved concepts at several Kilowatt power levels

Our Collaborators

• OCET
