6 FAQs about [Does wind power generation require ultra-high voltage transmission ]

What is ultra-high-voltage electricity transmission (UHV)?

Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers.

Are high-voltage direct current (HVDC) transmission systems suitable for offshore wind farms?

The advantages of high-voltage direct current (HVDC) transmission systems become more significant with the increase of both installed capacity and transmission distance in offshore wind farms. Therefore, this study discusses various voltage control methods for wind turbines and HVDC transmission systems.

Do high energy demand and low energy dependence affect UHV transmission projects?

Therefore, compared with other regions, regions with higher energy demand or higher energy dependence have more motivation to construct UHV transmission projects. They have more potential as the main inflow of electricity. What is the difference in the carbon emission effect of UHV transmission projects in areas with high and low energy dependence?

Do wind farms provide voltage support?

Wind energy is one of the primary types of renewable energy, and the installation is more concentrated than solar energy. The high penetration of offshore wind farms causes concern about frequency and voltage stability. Thus, many countries have requested wind farms to provide voltage support at the point of connection in their grid codes [ 1, 2 ].

How effective are UHV transmission lines?

UHV transmission lines feature high transmission efficiency, long transmission distance, low line loss, and flexible power deployment. These characteristics make them effective in overcoming the market segmentation of the power supply caused by the imbalance of China's regional energy resource endowment.

Can direct-current ultra-high-voltage transmission lines be decarbonized?

Projects are under way for direct-current ultra-high-voltage transmission lines that would allow trading of renewable electricity across world regions. Guo et al. use integrated assessment models to explore different scenarios for the operation of these projects and assess their potential for decarbonization.
