In a significant advancement for the energy sector, researchers from the State Key Laboratory of Power Grid Safety and Energy Conservation have published a study addressing the complexities of large-scale centralized new energy sending systems in China. This innovative power grid configuration, which increasingly integrates renewable energy sources, faces unique challenges that could impact the stability and efficiency of energy delivery.
The study, led by Shiying Ma, delves into the critical risks associated with high-voltage direct current (HVDC) systems, particularly in the context of fluctuating energy outputs from renewable sources like wind and solar. “The high proportion of new energy sources in our grid makes it imperative to understand the risks of voltage and frequency fluctuations,” Ma stated. This insight is crucial as the energy sector moves towards a more sustainable future, where the reliance on renewables is expected to grow exponentially.
One of the primary concerns highlighted in the research is the coordination between energy sources and the power network. The paper identifies several potential risks, including large voltage fluctuations and low-frequency oscillations, which could disrupt service and lead to significant economic implications. “Addressing these risks is not just a technical challenge; it has far-reaching implications for energy reliability and cost-effectiveness,” Ma added.
The research emphasizes the importance of modeling key elements such as the auxiliary control of excitation systems and generator protection. These elements are vital for maintaining stability in a grid that increasingly incorporates renewable energy. The study proposes a simulation evaluation process to help manage these risks, offering a framework that could serve as a reference for energy operators aiming to optimize their systems.
As the energy landscape evolves, the findings from this research could influence future developments in the integration of renewable energy into existing grids. By addressing these challenges head-on, energy companies can enhance their operational resilience and reduce the risk of outages, ultimately leading to more reliable service for consumers.
This study not only sheds light on the technical aspects of energy transmission but also underscores the commercial implications of effective risk management in the energy sector. With the ongoing transition to a greener economy, the insights from this research could be pivotal in shaping policies and strategies that ensure a stable and sustainable energy future.
The findings are detailed in the publication ‘发电技术’, which translates to “Power Generation Technology,” highlighting the ongoing dialogue in the industry about the future of energy systems.
