Special Issue Information

Dear Colleagues,

Microgrids and power electronic systems have been key to the large-scale integration of renewable energy sources in electrical utility systems. In this context, measurements of voltages, currents, and/or powers associated with the microgrids, inverters, and converters have played a leading role in the path traveled, particularly to control the associated systems. Real-time estimations of electrical variables can become a challenge when there are electronic switching and high electromagnetic interference levels. New research and emerging algorithms to improve these real-time estimations allow engineers to reduce the number of sensors in a system and, thus, the total control systems costs, as well as increasing reliability. Furthermore, predictions and real-time data treatment have become increasingly relevant, particularly in renewable systems with energy storage.

This Special Issue seeks to present new relevant research related to new measurement methods, new estimation methods, or new prediction algorithms applied to control systems either in microgrids or power electronic systems.

Topics of interest include, but are not limited to, the following:

  • Measurement, estimations and control in microgrids applications.
  • Observers and reduced sensor control of grid-connected converters.
  • Artificial Intelligence applied to sensors in microgrids and power electronics applications.
  • Kalman filter-based microgrid state estimation and control.
  • Low-cost sensors and digital processing systems for power electronics.
  • Sensors in power electronics.
  • New algorithms and Estimations in predictive control applied to power electronics.
  • Sensorless control in power electronic applications.
  • Sensorless control applied to fault tolerant electrical and electronic systems.
  • Predictions and data managements for renewable energy systems.
  • Prediction algorithms to determine the lifespan of energy storage systems.

Many electronic power distribution systems have strong needs for highly efficient AC-DC conversion that can be satisfied by using a buck-boost converter at the core of the power factor correction (PFC) stage. These converters can regulate the input voltage in a wide range with reduced efforts compared to other solutions. As a result, buck-boost converters could potentially improve the efficiency in applications requiring DC voltages lower than the peak grid voltage. This paper compares SEPIC, noninverting, and versatile buck-boost converters as PFC single-phase rectifiers. The converters are designed for an output voltage of 200 V and an rms input voltage of 220 V at 3.2 kW. The PFC uses an inner discrete-time predictive current control loop with an output voltage regulator based on a sensorless strategy. A PLECS thermal simulation is performed to obtain the power conversion efficiency results for the buck-boost converters considered. Thermal simulations show that the versatile buck-boost (VBB) converter, currently unexplored for this application, can provide higher power conversion efficiency than SEPIC and non-inverting buck-boost converters. Finally, a hardware-in-the-loop (HIL) real-time simulation for the VBB converter is performed using a PLECS RT Box 1 device. At the same time, the proposed controller is built and then flashed to a low-cost digital signal controller (DSC), which corresponds to the Texas Instruments LAUNCHXL-F28069M evaluation board. The HIL real-time results verify the correctness of the theoretical analysis and the effectiveness of the proposed architecture to operate with high power conversion efficiency and to regulate the DC output voltage without sensing it while the sinusoidal input current is perfectly in-phase with the grid voltage.
