Challenges and Successful Completion of Upgrading Emergency Generator System into Microgrid

How do you upgrade a standard emergency power system into a smart, self-sufficient microgrid?

We are thrilled to share that HY, along with our esteemed industry collaborators, addressed this very question at the 25th Conference of the Electric Power Supply Industry (CEPSI 2025) in Singapore.

Our team from HY, See Fong Ho and Pei Qi Chua, had the privilege of collaborating with experts from DSTA, ComAp Group, and Singapore Polytechnic on a technical paper.

Our paper, “Challenges and Successful Completion Of Upgrading Emergency Generator System Into Microgrid“, details the successful conversion of a conventional emergency power system into a smart, resilient microgrid.

Key insights include:

• Enhanced Resilience: The system interconnects generators at different sites, allowing a development to operate as a self-sufficient independent grid and share electrical loading during a power failure.
  
  
• Real-World Data: The paper shares actual on-site Testing & Commissioning (T&C) waveforms, showing the generators’ performance from startup to full parallel operation and load sharing.
  
  
• Solving Key Challenges: Practical solutions for overcoming major hurdles, such as managing power transformer inrush current during energization, are covered.
  
  
• Future-Ready Design: This microgrid is not just for today. It is designed to seamlessly integrate future distributed energy resources (DERs), including renewables and energy storage systems.

Congratulations to our team and all our collaborators on this significant contribution to building more resilient and future-proof power infrastructure!
