面向能源互联网的零碳园区优化规划关键技术与发展趋势

碳中和、碳达峰的践行,零碳园区是重点之一。新型电力系统背景下,园区的电力能源供应具有水/电/气/热高度融合、源网荷储强不确定、一二次拓扑结构复杂多样等特点,现有的规划设计技术较难满足其应用需求。为此,以零碳园区为主要研究对象,对其优化规划设计的研究现状、关键技术与未来发展趋势展开讨论。首先,从能源互联的角度阐述了零碳园区的内涵架构与其规划设计技术研究现状;其次,归纳并阐述了零碳园区包括能源-交通系统耦合、多能互补、能量梯级利用、需求响应、渐进式规划等优化规划关键技术;最后,从共享理念、数字孪生与云储能等方面分析了园区规划未来的发展趋势,从理念应用、学科交叉、信息融合与态势感知等角度指明了园区规划的技术挑战与研究方向,以期为我国面向能源互联网的零碳园区的发展提供更有力的技术支撑。

Key Technologies and Development Trends of Zero-Carbon Park Optimization Planning for Energy Internet

Zero-carbon park is one of the key points in the practice of carbon neutralization and emission peak. However, in the context of the new power system, the electric energy supply of the park is characterized by the high integration of water, electricity, gas and heat, strong uncertainty of source-grid-load-storage, and complex and diverse primary and secondary topologies, which makes it difficult for the existing planning and design technologies to meet the application requirements. To this end, this paper discusses the current status, key technologies and future development trends of the optimal planning and design of zero-carbon parks. Firstly, the current status of research on zero-carbon parks and their planning and design technologies is explained from the perspective of energy interconnection. Secondly, the key technologies for optimal planning of zero-carbon parks, including energy-transportation system coupling, multi-energy complementarity, energy gradient utilization, demand response, and progressive planning, are summarized and explained. Finally, the future development trend of park planning is analyzed in terms of sharing concept, digital twin and cloud energy storage, and the technical challenges and research directions of park planning are indicated from the perspectives of concept application, disciplinary intersection, information integration and situational awareness, in order to provide stronger technical support for the development of zero-carbon parks for energy internet in China.
