Coupling Mechanisms and Coordinated Control of Source–Load–Storage Devices in Power Systems with High Penetration of Renewable Energy and Power Electronics

Power systems are undergoing a rapid transition toward operation with high penetration of renewable energy and power electronic interfaced devices—often referred to in China as “double-high” power systems. While this transition enables low carbon electricity supply, it also fundamentally reshapes grid dynamics by reducing inherent inertia and short circuit strength, strengthening converter–grid interactions, and introducing new oscillation and stability challenges under diverse operating conditions. These changes make it increasingly important to understand the coupling mechanisms among heterogeneous source–load–storage resources that jointly provide fast voltage and frequency regulation as well as oscillation damping, and to develop coordinated control and optimization strategies that can enhance dynamic support for secure and stable system operation.This Research Topic focuses on the coupling mechanisms and coordinated control of source–load–storage devices in power systems with high penetration of renewable energy and power electronics. The topic aims to systematically explore the multidimensional challenges and coordinated control approaches required to enhance the dynamic support capability of modern power systems dominated by renewable energy and power electronic converters. The Research Topic emphasizes an integrated perspective—from device-level coupling mechanisms to system-level regulation—and encourages cross-layer theoretical innovation and methodological integration. The goal is to promote both theoretical advances and practical solutions that support the secure and stable operation of power electronic-dominated power systems.The Research Topic covers the following themes, including but not limited to:- Modeling and dynamic analysis of grid-connected converters- Oscillation mechanisms and stability analysis in multi-converter and multi-device power systems- Dynamic support capability and coordinated control of renewable energy clusters- Load modeling and aggregated behavior with high penetration of distributed energy resources (DERs)- Grid support from demand-side and flexible load resources- Identification of weak links and stability bottlenecks in high-renewable power systems- Coordinated voltage and frequency control in converter-dominated grids- Multi-timescale optimization and control for power system dynamic performanceThis Research Topic encourages submissions structured around three interconnected layers—generation clusters, load clusters, and the overall power system and welcomes integrated studies combining modeling, analysis, evaluation, control, and optimization. Research employing advanced computational and intelligent methods, such as data-driven modeling, reinforcement learning, and dynamic programming, is particularly encouraged. Through this article collection, we aim to establish a comprehensive technical pathway from mechanism analysis to coordinated system control, facilitating the integration of theoretical insights and engineering practice for improving the dynamic stability of modern power systems with high penetration of renewable energy and power electronics.
