About the Project
This project is part of a 4-year Dual PhD degree programme between the National Tsing Hua University (Taiwan) and the University of Liverpool (England). As part of the NTHU-UoL Dual PhD Award students are in the unique position of being able to gain 2 PhD awards at the end of their degree from two internationally recognised world-leading Universities. As well as benefiting from a rich cultural experience, students can draw on large-scale national facilities of both countries and create a worldwide network of contacts across two continents.
The latest set of projects targeted goal #11 from the UN Sustainable Development Goals: Sustainable Cities and Communities.
Microgrid (MG), as a localised group of distributed energy sources (DERs) and loads, can effectively improve the efficiency of energy production/ utilization and promote more renewable energy generations. MG becomes one of the key technologies to implement a future low carbon and sustainable energy system. Moreover, it can simultaneously provide multiple end-use needs of multi-energy such as heating/cooling/electricity for an increased energy efficiency and thus acts as the backbone of the future multi-vector energy system.
Although there are lots of researches reported for MG, control and optimal operation of the microgrid still face difficulties and challenges as follows: i) Modelling difficulties of large number of distributed DERs with fully coupled dynamics and total different time-scale dynamic; ii) Stability analysis and assessment against the time-varying operation points from the renewable generations and the flexible loads, the switch of operation modes and the fault-ride through capability requirement for self-healing distribution networks; iii) Low inertia and fast dynamic due to a significant proportion of power electronic-interfaced DG units. iv) Effect of uncertainties in MG is higher than those in bulk power systems, due to the reduced number of loads and highly correlated variations of available energy resources.
To tackle those challenges, this PhD project will combine the expertise from two world leading universities and aim at investigating cooperative and autonomous control strategy of microgrid. We will investigate robust and autonomous primary control at the device level to improve the fault-ride through capability and power quality, and fully local measurement-based feedback. Moreover, multi-agent based cooperative and consensus control will be investigated for the secondary control, with less communication than the centralised control solution. Stability analysis based on Lyapunov stability theory will be studied to access the MG stability region as well investigate the We will then extend to multi-vector energy system for an optimal solution of local smart energy system with heat/cool/electricity generation, consumption and storage. Digital simulation, hardware-in-the-loop simulation and experimental verification will carry out to verify the proposed control algorithms. Case studies will base on benchmark IEEE test system and real industrial micro-grid both countries.
