In recent years, with the rapid development of the power industry, power engineering design has gradually shifted toward intelligent and green approaches, emerging as a new industry trend. The adoption of cutting‑edge technologies—such as artificial intelligence and big data analytics—has ushered in more efficient and precise solutions for power engineering design, significantly enhancing both design quality and operational efficiency. At the same time, the widespread application of renewable energy has propelled power engineering design toward sustainable development. During the design process, engineers are placing greater emphasis on environmental protection and energy conservation, striving to create a cleaner, more efficient energy supply system for society. Furthermore, intelligent power system design has increasingly become a focal point in the industry; the deployment of new technologies like smart grids and digital substations is giving rise to entirely new paradigms for power system operation and management. Looking ahead, as electricity demand continues to rise and environmental protection standards grow ever stricter, the power engineering design industry will undoubtedly face even more transformations and challenges. Industry professionals must continuously learn, update their knowledge, and relentlessly pursue innovation, driving the power engineering design sector toward a smarter, greener, and more sustainable future.
