In the dynamic world of energy, the integration of distributed new energy sources into provincial power grids is a hot topic. Researchers are constantly seeking ways to ensure that these grids remain stable and reliable as they incorporate more renewable energy. A recent study, published in ‘Zhongguo dianli’ (China Electric Power), has shed new light on this complex issue. The research, led by Jiawei Li from the School of Electrical Engineering and Artificial Intelligence at Xiamen University Malaysia, focuses on the transient characteristics of different types of distributed new energy and their impact on grid stability.
Li and his team have developed typical models that aggregate these characteristics into what they call “active comprehensive load models.” These models are designed to provide a more accurate picture of how distributed new energy sources affect the stability of provincial power grids. The findings are significant, particularly for energy companies and grid operators looking to balance the integration of renewable energy with grid stability.
One of the key insights from the study is the impact of thermal power units. When these units are directly withdrawn from the grid due to distributed new energy consumption, the stability of the power grid can decrease. This is a critical finding for energy providers who are increasingly relying on renewable sources. “The direct withdrawal of thermal power units from distributed new energy consumption operation will lead to a decrease in the stability of the power grid,” Li explains. This highlights the need for careful planning and management as the energy sector transitions to more sustainable sources.
However, the study also offers a silver lining. When thermal power units are in a peak shaving state, their impact on the transient stability of the power grid is relatively small. This suggests that during peak demand periods, the integration of distributed new energy sources can be managed more effectively, reducing the strain on the grid.
The research published in ‘Zhongguo dianli’ (China Electric Power) underscores the importance of understanding the complex interactions between different energy sources and grid stability. As the energy sector continues to evolve, this kind of detailed analysis will be crucial for ensuring that power grids remain reliable and efficient. For energy companies, this means investing in advanced modeling techniques and adopting strategies that can mitigate the risks associated with the integration of distributed new energy sources. The future of energy is undoubtedly renewable, but the path to getting there requires a deep understanding of the technical challenges and solutions.
