摘要
随着“碳达峰·碳中和”战略目标的推进以及新型电力系统建设逐步开展,以风电、光伏为代表的新能源持续快速发展,大规模新能源的强不确定性和随机性对电力系统安全稳定经济运行构成了巨大考验。首先,深入分析了高比例新能源电力系统有功功率与频率控制在实时平衡、调频资源、市场发展、安全防御等方面面临的形势与挑战;其次,介绍了多控制区协同控制、多类型资源有序调用、经济调度与自动发电控制的协调配合、安全事件检测与防御、智能化与新技术5个方面的核心问题和研究进展;最后,围绕多控制主体有功频率控制、海量泛在资源协同控制、辅助服务市场闭环控制、风险防御能力提升、人工智能技术深化应用等重点研究方向进行了探讨和展望。
With the promotion of the strategic goal of“carbon emission peak and carbon neutrality”and the gradual development in constructing new power systems,the renewable energy represented by wind power and photovoltaic keeps developing rapidly.The strong uncertainty and randomness of the large-scale renewable energy pose a huge challenge to the safe and stable economic operation of the power system.First,the situation and challenges faced by active power and frequency control in the power system with high proportion of renewable energy in terms of real-time balancing,frequency regulation resources,market development,and security defense are analyzed in depth.Then,the core issues and research progress in five aspects consisting of multiple controlarea coordination control,orderly deployment of multiple types of resources,coordination between economic dispatch and automatic generation control,security event detection and defense,and intelligence and new technologies are introduced.Finally,the key research directions such as active power and frequency control of multiple control agents,collaborative control of massive ubiquitous resources,closed-loop control of auxiliary service markets,improvement of risk defense capabilities,and deepening application of artificial intelligence technology are discussed and prospected.
