The field of power systems and renewable energy conversion is witnessing significant developments, with a focus on improving frequency control and stability in power systems. Researchers are exploring novel approaches to evaluate and enhance frequency control strength, including the development of new metrics and methods for comparing the effectiveness of different power systems. Additionally, there is a growing interest in designing and optimizing control strategies for renewable energy converters, such as wave energy converters and tidal current converters, to improve their efficiency and minimize environmental impacts. Noteworthy papers in this area include:

• A Comprehensive Approach to Evaluate Frequency Control Strength of Power Systems, which introduces a novel concept of frequency control strength and provides a comprehensive comparison of four real-world power systems.
• Implementing General-Order Frequency Dynamic Response Model and Frequency Excursion Duration Criterion in Unit Commitment Problem, which proposes a novel approach for incorporating frequency dynamics into the unit commitment problem.
• Real-Time Single-Iteration Model Predictive Control for Wave Energy Converters, which presents a novel real-time algorithm for controlling wave energy converters.
• Analysis and Control of Acoustic Emissions from Marine Energy Converters, which investigates the mitigation of acoustic emissions from tidal current converters through optimized control strategies.
