Research experience

Consensus-based Energy Management of Microgrid with Random Packet Drops

  • In this paper, we theoretically analyze the failure of conventional consensus-based energy management algorithms with random packet drops. We propose a novel consensus-based algorithm with running-sums, and theoretically prove the optimality of the solution and the convergence of the algorithm.

Decentralized Energy Management of Microgrid Based on Blockchain-Empowered Consensus Algorithm with Collusion Prevention

  • In this paper, we propose a blockchain-empowered microgrid energy management framework and a consensus-based energy management algorithm over random communication topology, to enable trusted coordination among agents and prevent collusion between malicious agents.
  • Accepted for publication in IEEE Transactions on Sustainable Energy, DOI: 10.1109/TSTE.2023.3258452.

Impact of COVID-19 on Urban Energy Consumption of Commercial Tourism City

  • In this paper, we study the impact of the COVID-19 pandemic on the energy sector in commercial tourism cities. We analyze the impact of COVID-19 pandemic on Macau’s overall energy consumption and different fields. A detailed comparison with the energy characteristics of different countries is also presented.

Distributed, Consensus-based Coordination of Demand Response

  • In my master thesis, we study the local flexibility transaction in the distribution network level, using both centralized method and distributed consensus-based method.

Consensus-based Distributed Control for Energy Storage Devices in Isolated Microgrid

  • In my bachelor thesis, we study the consensus-based distributed control of energy storage devices in the microgrid. We also validate the algorithm’s ability to operate under communication delay and small scale failure.
  • Awardee of Outstanding Undergraduate Thesis.

Online Monitor Device for Insulation of Distribution Cable

  • In this project, we study the detection of leakage current in μA\mu A-level in the context of AA-level working current.
  • We won the first prize in “Challenge Cup” National Undergraduate Extra-Curricular Academic Science and Technology Works.
