Resource Aggregation for Low-Carbon Power Systems at the Transmission Level
摘要
The role of one transmission sub-system in the low-carbon power system is for renewable electricity delivery from the generation side to the load side. With the fast development of global renewable installations, energy balance in one single transmission sub-system becomes more difficult due to the inevitable power fluctuations from renewable integration [1]. This further necessitates interconnected transmission sub-systems by which rich renewable integration in one transmission sub-system can be delivered to another transmission sub-system with poor renewable integration, contributing to smoothening renewable fluctuations to simultaneously maintain energy balance [2]. Consequently, tie-line power flow exchanges among different transmission sub-systems play a vital role in the insurance of their energy balance in a broad resource configuration.
