In the rapidly evolving landscape of renewable energy, the integration of distributed resources (DR) into the power grid is becoming increasingly crucial. A recent study led by Guoqing He from the State Key Laboratory of Operation and Control of Renewable Energy & Storage Systems at the China Electric Power Research Institute sheds light on the technical standards governing this integration, both domestically and internationally. The study, published in ‘Zhongguo dianli’ (translated to ‘China Electric Power’), offers a comprehensive comparison of DR grid integration standards across North America, Europe, and China, highlighting key differences and future trends.
The study delves into various aspects of DR grid integration, including power control, grid adaptability, power quality, synchronization, and safety and protection. He and his team found that while there are similarities in the standards across regions, there are also notable differences that could impact the global energy sector. “The main differences between North American, European, and Chinese standards lie in their approaches to power control and grid adaptability,” He explains. “These differences can significantly affect how distributed resources are integrated into the grid, influencing everything from operational efficiency to safety protocols.”
One of the most compelling findings is the emphasis on fault ride-through (FRT) capabilities. FRT is a critical aspect of grid integration that ensures distributed resources can continue to operate during grid disturbances, maintaining stability and reliability. The study reveals that European standards tend to be more stringent in this area, which could set a benchmark for global practices. “European standards often require higher FRT capabilities, which could drive innovation in this area and potentially influence global standards,” He notes.
The implications of this research are vast for the energy sector. As the world shifts towards more decentralized and renewable energy sources, understanding and harmonizing these standards will be essential for seamless integration and operational efficiency. For equipment manufacturers and DR developers, this study provides valuable insights that could shape their product development and market strategies. “The development and review of DR grid integration standards in China, as well as globally, will be crucial for the future of the DR industry,” He emphasizes.
The study also highlights the need for ongoing updates to Chinese DR standards to align with global best practices. This could open up new opportunities for collaboration and innovation, driving the energy sector towards a more sustainable and resilient future. As the energy landscape continues to evolve, research like He’s will play a pivotal role in shaping the standards that govern our power grids, ensuring they are ready to meet the challenges of tomorrow.
