Special Issue Information

Dear Colleagues,

Over the last decade, power quality (PQ) has garnered significant attention for a number of fundamental reasons. First and foremost, assured power quality is a product that provides benefits for both customers and the grid operators. Second, by continuously monitoring the quality of power coming from the electrical grid or network, significant amounts of energy and costs can be saved. Cost-effective maintenance or upgrades to transmission and distribution assets can be based upon measurements. The global liberalization of the electrical power industry is the third factor contributing to the increased attention being paid to power quality. Customers are now seeking improved performance from electricity suppliers due to their increased awareness of power quality issues.

In this dynamic environment, it is critical to monitor, maintain, and enhance power quality levels to ensure compatibility between producers, consumers, and the entire energy power system. In order to improve the power quality in microgrids and smart grids, active power filters, inverters, and other power-electronics-based equipment is needed for the development of superior controllers. New challenges arise due to the emissions from these new devices, which either produce or consume energy and are connected to the transmission or distribution network, particularly those that have an active power electronics interface; new smart distribution applications, like demand-side management, feeder reconfiguration, and Volt/VAR control; and the increased sensitivity of modern installations used by producers or end users.

We invite cutting-edge research and both theoretical and experimental studies exploring recent advances in this field.

This research paper introduces a new topology for multilevel inverters, emphasizing the reduction of harmonic distortion and the optimization of the component count. The complexity of an inverter is determined by the number of power switches, which is significantly reduced in the presented topology, as fewer switches require fewer driver circuits. In this proposed topology, a new single-phase generalized multilevel inverter is analyzed with an equal magnitude of voltage supply. A 9-level, 11-level, or 13-level symmetrical inverter with RL load is analyzed in MATLAB/Simulink 2019b and then experimentally validated using the dSPACE-1103 controller. The experimental verification of the load voltage and current with different modulation indices is also presented. The analysis of the proposed topology concludes that the total required number of components is lower than that necessary for the classical inverter topologies, as well as for some new proposed multilevel inverters that are also compared with the proposed topology in terms of gate driver circuits, power switches, and DC sources, which thereby enhances the goodness of the proposed topology. Thus, a comparison of this inverter with the other topologies validates its acceptance. Full article
