Smart Grid, Integration of Renewable Sources and Improvement of Power Quality

Dear Colleagues,

Against the backdrop of the pressing global demand for decarbonization and the rapid proliferation of renewable energy sources, the global energy landscape is undergoing a profound transformation. This transition from traditional, centralized power systems based on fossil fuels to distributed networks dominated by renewables presents unprecedented challenges and opportunities. The inherent intermittency and variability of sources such as solar and wind demand that the power grid possess greater intelligence, flexibility, and resilience. The smart grid, integrated with advanced communication, control, and data analytics technologies, serves as the cornerstone for building modern energy infrastructure. However, the grid integration of large-scale renewable energy and emerging loads, such as electric vehicles, can trigger severe power quality issues—including voltage fluctuations, harmonics, and frequency instability—thereby threatening the reliable operation of the entire system.

This Special Issue, "Smart Grid, Integration of Renewable Sources and Improvement of Power Quality," aims to showcase and disseminate the latest advances, innovative research, and comprehensive reviews that address the key intersecting challenges across these three interrelated domains. We seek to foster a multidisciplinary academic discussion on technologies, strategies, and policies to facilitate the seamless integration of renewable energy, enhance the intelligence and resilience of the power grid, and ensure high-standard power quality for all users.

Topics of interest for this Special Issue include, but are not limited to, the following:

Smart Grid Technologies and Architectures:

• Data analytics and artificial intelligence applications in grid management.
• Demand-side management, demand response, and energy efficiency enhancement.
• Design, control, and operation of microgrids, nanogrids, and islanded power systems.
• Communication protocols, cybersecurity, and resilience of smart grids.

Renewable Energy Integration:

• Grid integration challenges and solutions for large-scale solar PV and wind power.
• Energy storage systems for grid stability and renewable energy smoothing.
• Advanced power electronic interface technologies.
• Grid-forming and grid-following control strategies.
• Electric vehicle grid integration and vehicle-to-grid
• Virtual power plants and distributed energy resource aggregation technologies.

Power Quality Improvement:

• Monitoring, analysis, and diagnosis of power quality disturbances.
• Mitigation techniques for harmonics, voltage sags/swells, flicker, and unbalance.
• Impact of renewable energy and EV charging on power quality.
• Power quality standards, regulations, and economic analysis.

We look forward to receiving your outstanding contributions.
