Using Dynamic Line Rating to Enhance Flexibility of Wind-involved Hybrid Energy System
- Idaho National Laboratory: 2525 Fremont Ave, Idaho Falls, ID, 83402 (United States)
By providing real-time overhead line ampacity, Dynamic Line Rating (DLR) is a potential technique to solve the transmission congestion issues that are threatening NPPs, especially when a nuclear plant is coupled with wind turbine generators. First, DLR can utilize the concurrent cooling effect and dynamic monitors on transmission lines to increase the line carry capacity and reduce congestion. Second, more frequent interactions between transmission lines and operators can increase the flexibility and create a more dynamic and responsive hybrid system. In general, DLR can increase the flexibility and optimize the efficiency of a hybrid system utilizing wind energy. DLR helps meet continuously fluctuating electricity demands with real-time observation of transmission lines for more accurate estimation of line carry capacity. For the fuel energy, DLR can contribute greatly in saving fuels and reducing carbon emission by providing timely information for adjusting generation levels. For HES's including NPPs, transmission congestion could be more serious and needs attention. Therefore, by providing additional transmission capacity, DLR can contribute to alleviate the congestion and congestion pricing impact that is threatening the current NPPs and prevent potential congestion that may constrain the operation of future hybrid system involved with a nuclear plant. However, either a fuel plant or nuclear plant is better coupled with a wind turbine to take advantage of the concurrent cooling effect and dynamic monitoring. The research team at Idaho National Laboratory, currently focused on the benefit of DLR technology to assist wind generation, is now exploring the feasibility of implementing the same technology into such HES and NPP. Future work will focus on the analysis of technique feasibility, challenges and benefit-cost analysis of integrating DLR into HES. Detailed studies are anticipated to evaluate the benefits of DLR on HES and NPP with transmission constraints. This paper explores a potential utilization of DLR in hybrid energy systems, especially those involving traditional fossil fuels or nuclear power coupled with wind energy. The goal is to increase the efficiency and flexibility of these types of hybrid systems in order to provide more secure, reliable and low-carbon energy.
