Abstract
With the background of continuous urbanization and global transformation of energy systems towards decentralized, smart and low carbon manners, the traditional supply-side oriented single-direction urban energy supply paradigm is out of date. The integrated urban energy system emerges, which integrates multiple energy sectors to satisfy the urban electricity, heating, cooling and gas demands simultaneously. However, to determine the best design of the complicated integrated urban energy system is a challenge in the energy system research field. Hence, this thesis establishes the optimization model for the integrated urban energy system with a particular focus on the multi-scale modelling and optimization perspective. Efficient problem-solving strategies are proposed and comprehensive analysis is conducted for such a system to explore the best system design and dispatch strategies. Through a case study, the proposed approach is verified that can efficiently model and solve the optimization problem for the large-scale integrated urban energy systems.
