In the vast landscapes of remote renewable energy bases, a significant challenge looms: maintaining frequency stability without the backing of conventional power sources. Lingling Tan, a researcher from Shandong Electric Power Engineering Consulting Institute Co., Ltd., has tackled this issue head-on with a novel approach that could reshape how we integrate renewable energy into our grids.
Tan’s research, published in the Chinese journal *Electric Power* (Zhongguo dianli), introduces a bi-level optimization method for configuring grid-forming energy storage systems. This method not only enhances frequency stability but also maximizes the utility of energy storage systems, potentially reducing the need for excessive configurations.
The upper level of Tan’s model focuses on economic optimization, determining the most cost-effective configuration for grid-forming energy storage while considering operational constraints. The lower level delves into frequency security, optimizing the inertia response and primary frequency regulation parameters of the energy storage system to ensure stability under anticipated power disturbances.
“This approach ensures that we are not just throwing more storage at the problem, but rather, we are making the most of what we have,” Tan explains. By co-optimizing inertia response and primary frequency regulation, the method maximizes the frequency support capability of grid-forming energy storage, making it a more viable and economical solution for remote renewable energy bases.
The implications for the energy sector are substantial. As we transition towards cleaner energy sources, the need for effective frequency regulation becomes increasingly critical. Tan’s research offers a promising solution that could accelerate the integration of renewable energy bases into our power grids, enhancing stability and reducing costs.
Moreover, the validation of this method using historical data from a typical scenario in Northwest China underscores its practical applicability. As Tan notes, “The effectiveness of this optimization method has been proven in real-world scenarios, making it a valuable tool for energy providers and planners.”
This research not only addresses a pressing technical challenge but also opens up new avenues for commercial opportunities in the energy sector. By optimizing the use of grid-forming energy storage, energy providers can reduce costs and improve the reliability of renewable energy bases, making them more attractive to investors and consumers alike.
In the broader context, Tan’s work contributes to the ongoing global effort to enhance grid stability and reliability as we transition towards a more sustainable energy future. As the energy sector continues to evolve, innovative solutions like Tan’s will play a pivotal role in shaping the landscape of renewable energy integration.
