Special Issue Information

Dear Colleagues,

This is a call for papers for the Topic “Power Electronics and Renewable Energy Technologies”. With the increase of the global population and the rapid development of industry, the energy demand is increasing very rapidly. Over the past few centuries, this demand has mainly been met by fossil fuels. Looking into the future, however, fossil fuel resources are limited and their consumption causes serious environmental problems. Hence, governments and companies are increasingly seeking to reduce the world’s dependence on fossil fuels. This makes it essential to develop sustainable energy solutions for energy production, such as photovoltaics, wind turbines, hydropower, hydrogen, etc. At the same time, energy saving through the use of new technologies is also critical. Power electronics technology, which utilizes power semiconductor devices to convert and control electrical energy, plays a key role in both situations discussed above. For instance, power electronics are used to interface renewable sources to maximize the energy yield from photovoltaics and wind turbines, and to smoothly integrate it into the grid. Meanwhile, power electronics can ensure a large amount of energy saving, as in LED drivers, pumps and compressors. This topic provides a global platform to present the latest research papers related to power electronics and renewable energy technologies. Relevant themes include but are not limited to the following:

  • Power electronic converters and control systems.
  • Renewable energy technologies (e.g., photovoltaics, wind turbines and fuel cells).
  • Distributed generation and grid interconnection.
  • Electric vehicles and intelligent transportation.
  • Energy storage, battery charging and management te
  • Microgrid and smart grid.
  • Lighting technologies.
  • Electric machines and drives.
  • Power quality issues.
  • Wide-bandgap devices.

A static synchronous compensator (STATCOM) is a powerful mechanism for balancing reactive power and uplift voltage stability in a transmission system. Nowadays, the desire to save energy by reducing losses is prioritized as an essential target instead of increasing the power generation for the sustainability of any nation’s growth plans. As a result, power-electronics-based converters are more significant for power savings in transmission systems. STATCOM based on voltage source converters (VSC) are operated to improve on stable performance conditions as well as to minimize the harmonic distortions in a power system. Hence, this paper explores low harmonic distortions of fifteen-level VSC structured STACOM using only one DC-link voltage to balance the reactive power and to manage the voltage profile in large power transmission systems. STATCOM consisting of H-bridge type VSCs and binary weighted transformers was utilized to maintain an AC system voltage at 132 kV, 50 Hz. The three stages of VSCs were operated with meticulous firing angles based on converter levels for controlling THD (total harmonic distortion) and providing system improvement. The proposed model of the fifteen-level H-bridge type voltage source converters with fuzzy logic decoupled control algorithm based STATCOM can be used for large power range applications with a small number of switches. This model attained stable operation of the system with a low harmonic deviation at any dynamical conditions. The simulation results using MATLAB showed that the system’s operation was enhanced, with a smoother response and improved steady state performance. Full article
