The increasing penetration of renewable energy sources (RES) in the utility and introduction of new generation topologies as microgrids and distributed generation systems have increased the penetration of power converters in modern power systems. At present, power converters (PC) are used in a wide range of applications, such as electric vehicles, microgrids, renewable energy conversion systems, variable speed drives, power conditioners, high voltage direct current (HVDC) transmission, energy storage systems, traction systems, etc.
The high penetration of generation units based on power converters reduces the total rotational inertia available in a system, and this negatively impacts its stiffness and power system stability. Therefore, new control systems have to be developed to improve the performance of power converter based generation units, and it is now expected that they provide ancillary services, such as frequency and voltage support, harmonic compensation, as well as synthetic inertia emulation. New droop control methods have to be applied to PC-based generation units to achieve active and reactive power sharing, distributed averaging proportional integral controllers or centralized systems used to provide frequency regulation, in microgrids, etc.
Despite these several requirements, most PCs use control systems that rely on cascaded linear control. However, cascaded linear control could lead to performance limitations, inflexibility, and limited bandwidth.
Therefore, it is essential to develop advanced control strategies for power conversion systems so that the robustness, flexibility, and dynamic performance of modern power systems can be significantly improved.
Editors invite original manuscripts presenting recent advances in these fields with particular reference but not limited to:
- Novel modeling approaches and control strategies for PC based RES
- Novel modeling approaches and control strategies for microgrids and distributed generation systems
- Robust, predictive, nonlinear, passivity-based control of PC and RES
- Modeling and control of power systems with high penetration of RES
- Ancillary services for PC-based RES
- New control systems and topologies for large power RES applications
- Grid integration of large power RES
- New control systems for wind energy and PV conversion systems

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
