| dc.description.abstract | This thesis aims to investigate the optimal operation of three forms of Urban Power Systems (UPSs) which will be co-existence in a long time. First of all, aiming at AC / DC hybrid distribution system, the thesis proposes a comprehensive optimal dispatching model with centralized two-stage dispatching framework, achieving a 25.9% reduction in power loss compared to the initial model and increasing the integration of renewable distributed generations from 71% to 200%. Secondly, aiming at AC / DC hybrid active distribution system, the thesis incorporates social behaviours of electric vehicles and power demand response within a three-stage energy management framework, leading to a 13.07% enhancement in social welfare and a 19.90% increase in calculation speed. At last, aiming at transmission and distribution coupling system, the thesis proposes a two-layer optimal dispatching framework that takes into account the switching sequence along with dynamic thermal rating, leading to the effective resolution of congestion issues across various scenarios while maintaining a safety margin. In general, the models and optimization dispatching framework proposed in this thesis can help achieve the optimal power flow for UPSs, and improve its economic, security, and stable operation. | |
