Abstract
Over the last decades, serious climate change has caused significantly increase in frequency and severity of extreme weather events, causing devastating impacts on people's lives and livelihoods, also unprecedented challenges to power system, especially islands or remote communities. Besides power supply reliability, power system resiliency is getting more and more important under this background. To prevent further climate change deterioration, an urgent energy system transition from fossil fuel to renewable energy is happening worldwide swiftly. With a substantially increase of distribution energy resources (DERs), energy coordination or energy management could play an important role in increasing power system resiliency. Motivated by the remarkable role DERs could play in energy transition and improving distribution power system resiliency, my research has mainly focused on following topics :Firstly, with a collective effort from former researchers, a complete set of resilience metrics is proposed for intuitively monitoring distribution power system resilience status and providing decision support in operation and planning. Secondly, a proactive energy resource coordination strategy is proposed for the economic and resilient operation of an islanded hydro-diesel-battery microgrid. Further, device failure uncertainty caused by extreme weather events is considered, and thus an uncertainty-involved microgrid energy management strategy is proposed. Additionally, a microgrid BESS sizing model is proposed to meet isolated operation duration requirements, an increasingly important concern of microgrids as extreme weather events getting more severe and frequent. Finally, a two-stage restoration strategy with the assistance of ESAT (Enhanced Situational Awareness Tool) is proposed.
