Challenges to the reliability and stability of power systems with a high proportion of new energy penetration
The large-scale integration of new energy into the grid can play a role in replacing traditional power plants
Jan 10,2022
The large-scale integration of new energy into the grid can play a role in replacing traditional power plants, but due to its strong intermittency, volatility, and randomness, the confidence capacity at the peak period is limited, making it difficult to effectively play its peak role, resulting in difficulties in power balance. Especially under extreme weather conditions, the output of new energy generation is limited, equipment tolerance is fragile, and continuous and reliable power supply faces difficulties.
On the other hand, the large-scale integration of new energy into the grid has led to a highly electronic power system, posing new challenges to the safe and stable operation of the system. In recent years, multiple incidents related to large-scale grid connection of new energy have occurred both domestically and internationally, such as the "8-9" power outage in the UK and the "7.1" synchronous oscillation in Hami, Xinjiang. These incidents indicate that the safety and stability issues of new power systems dominated by new energy have expanded from traditional working frequency bands to mid to high frequency bands, exhibiting new characteristics such as broadband oscillation. Therefore, it is necessary to strengthen research on relevant guarantee technologies.
