Special Session 3
Frequency Stability and Control in Regional Power Grids with Multi-Source Renewable Energy Integration

"多源可再生能源接入下区域电网频率稳定与控制关键技术"

Driven by the national "Dual Carbon" strategic goals, the penetration of fluctuating renewable energy sources, such as wind and photovoltaic (PV) power, in regional power grids has been rapidly increasing. The large-scale replacement of conventional synchronous generators by these renewable energy units has led to a significant reduction in system rotational inertia. Furthermore, the inherent randomness and intermittency of their power output severely weaken the grid's primary frequency regulation capability. These factors contribute to increasingly prominent frequency fluctuations, posing serious challenges to the secure and stable operation of the power system. This special issue aims to explore strategies for fully leveraging and coordinating the regulation potential of diverse resources, including wind, PV, and conventional hydropower. The objective is to facilitate the development of a new collaborative frequency defense framework to ensure the dynamic security of power grids with a high share of renewable energy.

在“双碳”战略目标的推动下，风电、光伏等波动性可再生能源发电在区域电网中的渗透率迅猛增长。这些新能源机组大规模替代传统同步发电机，导致系统旋转惯量显著下降，其出力的随机性与间歇性也严重削弱了电网的一次调频能力，致使频率波动问题日益突出，对系统安全稳定运行构成严峻挑战。本特刊旨在探讨如何充分挖掘与协调风电、光伏、常规水电等多种资源的调控潜力，构建新型频率协同防御体系，以保障高比例新能源电网的动态安全。
