In the ever-evolving landscape of energy management, ensuring a stable power supply is paramount. As renewable energy sources like wind and solar become more prevalent, and extreme weather events become more frequent, the challenge of maintaining grid stability has never been greater. Enter a groundbreaking study published by WANG Shen, a researcher at the National Power Dispatching and Control Center, State Grid Corporation of China, which offers a novel approach to inter-provincial power support strategies.
The research, published in Zhejiang dianli, which translates to ‘Zhejiang Electric Power’, introduces a method for generating inter-provincial power support strategies based on ultra-short-term balance margin. This innovative approach aims to address the significant challenges posed by the integration of large-scale renewable energy sources and the increasing occurrence of extreme weather events.
At the heart of this method is the assessment of power balance capability and risks through ultra-short-term power balance margin and power supply capacity indicators. “By accurately assessing the risk of large-scale power grid imbalance in real-time,” WANG explains, “dispatchers can utilize inter-provincial AC/DC systems for wide-area mutual power support, ensuring a more stable and reliable power supply.”
The method proposed by WANG and his team involves several key steps. Firstly, it assesses the power balance capability and risks using ultra-short-term indicators. Secondly, it generates inter-provincial power support strategies considering the security constraints of AC/DC systems. Finally, the effectiveness and practicality of the method are verified through case studies using actual grid operation data.
The implications of this research for the energy sector are substantial. As power grids become more interconnected and reliant on renewable energy sources, the ability to accurately assess and mitigate balance risks in real-time will be crucial. This method could revolutionize the way power is managed and distributed across provinces, ensuring a more reliable and stable power supply.
Moreover, the commercial impacts of this research are significant. By enabling more efficient and effective power management, this method could lead to cost savings for energy providers and consumers alike. It could also pave the way for further innovations in the field of power grid management, shaping the future of the energy sector.
As WANG notes, “Practical applications show that dispatchers can use this method to accurately assess balance risks of large grids and rapidly generate inter-provincial power support strategies.” This could lead to a more resilient and adaptable power grid, better equipped to handle the challenges of the 21st century.
In an era where the demand for reliable and sustainable power is higher than ever, this research offers a promising solution. By providing a method for accurate real-time assessment and mitigation of power balance risks, it could shape the future of power grid management and pave the way for a more stable and sustainable energy future.
