CUHK Cross-institutional Theme-based Research Scheme (TRS) Project: Developing High-performing and Energy-saving Microgrids for Field Implementation

In 2013–14, CUHK was awarded HK$ 60.33 million by the “Theme-based Research Scheme” of the University Grant Council of the Hong Kong Government for the 5-year project “Smart Solar Energy Harvesting, Storage, and Utilization”. Led by Prof. Ching-ping Wong, Dean of Engineering, CUHK, and more than 20 expert scholars from CUHK, PolyU, HKUST and HKU worked collaboratively through results in stages.

In the area of power system operation, Prof. Minghua Chen and his team developed a paradigm-shift online algorithm for cost-minimised energy generation scheduling in microgrids. They broke through the conventional prediction-based scheduling paradigm and proposed an online algorithm called CHASE (Competitive Heuristic Algorithms for Scheduling Energy-generation), which is based on intelligent tracking of the behaviours of perfect dispatch. In a case study of a virtual microgrid based on traces in the San Francisco area, with little or no generation/load forecast information, the CHASE algorithm was able to bring about a remarkable 20% cost saving.

On the other hand, Prof. Dah-ming Chiu and his team helped build a smart online energy management platform, “Woo Sing Power” which provides instantaneous feedback to each room, raises the awareness in the students of energy consumption and conservation and assists administrators to find opportunities and policies to save energy.
