Recent Advances in Power Quality Analysis and Robust Control of Renewable Energy Sources in Power Grids: 2nd Edition

Dear Colleagues,

In modern power grids with a large share of distributed power production, achieving high power quality is a challenging task. The integration of renewable energy sources (RESs) into power grids has introduced various disturbances such as harmonic distortions, voltage sags, frequency variations, voltage unbalance, etc., thereby leading to the degradation of power quality. In particular, the variable nature of RESs may cause rapid changes in voltage; consequently, a protection system can cause the disconnection of different parts of a power system.

To enable the flexible operation of RESs, voltage source converters and associated control systems are necessary. Several RESs with storage devices, loads, and voltage source converters are often connected in so-called microgrids. Microgrids are an emerging concept, closely connected with power quality, novel control methods, the Internet of Things, cyber security, etc. They are designed to function either in grid-connected or standalone mode, depending on their energy potential and grid code requirements.

Since around 30% of the world’s electricity generation comes from RESs (including hydropower), the problems and challenges in integrating RESs into power grids and designing the associated control systems are the focus of much research.

The objective of this Special Issue is to bring together recent, high-quality papers related to the theory and practice of power quality in power grids with a significant share of RESs.

Relevant topics include but are not limited to the following:

• Power quality monitoring;
• Control of power quality mitigation devices;
• Active filtering of voltage and current harmonics;
• Power quality problem mitigation;
• Control methods for AC, DC, and hybrid microgrids;
• Advanced control methods for power converters;
• Stability of microgrids;
• Control of storage devices;
• Advances in the economic aspects of microgrids;
• Cyber security, data processing, and smart loads in microgrids;
• Electromagnetic interference in microgrids.
