Review and Prospect of Research on Active Power and Frequency Control in Power System with High Proportion of Renewable Energy

With the promotion of the strategic goal ofcarbon emission peak and carbon neutralityand 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 control-area 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. © 2023 Automation of Electric Power Systems Press.
