Special Issue Information

Dear Colleagues,

The transition to low-carbon energy systems has positioned renewable energy as a central research priority worldwide. Technologies such as solar, wind, hydropower, biomass and geothermal are expanding rapidly owing to technological progress, declining costs and increasing policy support. Nevertheless, their large-scale deployment raises important challenges related to grid integration, power system stability, energy storage, forecasting and market adaptation. This research area is scientifically significant because it brings together power engineering, energy economics, digital innovation and sustainability analysis. Advancing knowledge in these areas is essential for enabling reliable, efficient and resilient energy systems and for supporting long-term decarbonization goals.

This Special Issue aims to present recent scientific advances and practical developments in renewable energy, with particular emphasis on power systems, energy markets and related technological applications. It welcomes high-quality contributions addressing renewable integration, smart grids, storage, market design, optimization and emerging digital technologies. The proposed topic aligns closely with the journal’s scope by addressing key issues in sustainable energy systems, power system innovation, energy management and low-carbon technologies. It further supports the journal’s commitment to publishing interdisciplinary research that combines theoretical analysis, modeling and real-world applications.

This Special Issue welcomes contributions on a broad range of topics related to renewable energy development, including solar, wind, hydropower, biomass, geothermal and hybrid energy systems, as well as their integration into modern power systems. Particular attention is given to smart grids, microgrids, distributed energy resources, energy storage and system flexibility. The issue also encourages studies on electricity markets, pricing mechanisms and policy frameworks, together with emerging applications of artificial intelligence, IoT, hydrogen, power-to-X and electric vehicles.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Renewable Energy Technologies and Hybrid Energy Systems
  • Renewable Energy Policy Mechanisms
  • Carbon Pricing and Incentive Design
  • Multi-Market Coordination
  • Renewable Energy Integration into Power Systems
  • Smart Grids, Microgrids and Distributed Energy Resources
  • Energy Storage and System Flexibility
  • Electricity Markets, Regulation and Policy Frameworks
  • Artificial Intelligence, IoT and Digital Applications in Energy Systems
  • Hydrogen, Power-to-X and Sector Coupling
  • Electric Vehicles and Vehicle-to-Grid Technologies
  • Techno-Economic, Environmental and Sustainability Assessments

We look forward to receiving your contributions.

Against the backdrop of accelerating transitions to sustainable energy systems, the optimal operation of microgrids and the high-efficiency integration of renewable energy face growing technical challenges, which highlight the necessity of tapping into flexible multi-energy resources to the fullest extent. Aiming at low-carbon microgrid systems with electro-thermal demands, this paper proposes a sustainable dispatch strategy that actively integrates waste heat recovery and building thermal inertia. First, a refined mathematical model of a Hybrid Energy Storage System (HESS) is developed, considering waste heat recovery processes from the electrolyzer and the fuel cell. Second, an optimal dispatch model considering the HESS and building thermal inertia (BTI) is constructed, the PMV index is adopted to quantify the adjustable margin of user thermal demand, and the objective function accounts for multiple economic and environmental indices, including energy procurement costs, equipment maintenance costs, and carbon emission trading costs. Case studies show that this strategy can effectively enhance the regulation flexibility of the system, significantly reducing comprehensive operational costs by up to 51.6% and improving local renewable energy accommodation while ensuring environmental sustainability and low-carbon operation.
