Advances in Hydraulic, Wind, and Photovoltaic Power Generation Systems

Dear Colleagues,

The rapid transition toward low-carbon and sustainable energy systems has positioned hydraulic, wind, and photovoltaic (PV) power generation as cornerstone technologies of the modern power sector. As these renewable resources continue to scale up and penetrate power grids worldwide, new challenges and opportunities have emerged in system design, performance enhancement, operational reliability, forecasting accuracy, and coordinated integration. Addressing the inherent variability, uncertainty, and complexity of water–wind–solar systems requires continuous advances to be made in theory, technology, and practical methodologies.

In this Topic, we invite contributions that explore recent advances in hydraulic, wind, and photovoltaic power generation systems, covering the full lifecycle from resource assessment and system design to operation, maintenance, and end-of-life management. We particularly welcome studies on innovative technologies and methods such as advanced turbines and converters, intelligent control strategies, high-fidelity modeling and simulation, data-driven forecasting of power output and resources, condition monitoring, fault diagnosis, predictive maintenance, and lifecycle performance assessment. Research leveraging artificial intelligence, digital twins, uncertainty quantification, and multi-source data fusion to improve reliability, efficiency, and resilience is especially encouraged.

Furthermore, this Topic seeks contributions on the coordinated planning and optimal operation of hydro–wind–solar hybrid systems and their integration with energy storage, power grids, and emerging energy markets. Topics of interest include joint optimization of generation scheduling, water–energy coupling, flexibility provision, grid support services, and strategies to enhance system stability under high renewable penetration. Case studies, real-world applications, and comparative analyses that bridge theory and practice are highly valued.

By collating interdisciplinary research, methodological innovations, and practical experiences, this Topic aims to foster a deeper understanding of next-generation hydraulic, wind, and photovoltaic power generation systems. We welcome original research articles, reviews, and technical communications that contribute to advancing efficient, reliable, and sustainable renewable energy systems, supporting the global transition toward a resilient and carbon-neutral energy future.
