Multilevel inverters: A literature survey on topologies and control strategies

Abstract: Multilevel inverters have been attracting in favor of academia as well as industry in the recent decade for high-power and medium-voltage energy control. In addition, they can synthesize switched waveforms with lower levels of harmonic distortion than an equivalently rated two-level converter. The multilevel concept is used to decrease the harmonic distortion in the output waveform without decreasing the inverter power output. This paper presents the most important topologies like diode-clamped inverter (neutral- point clamped), capacitor-clamped (flying capacitor), and cascaded multilevel with separate dc sources. This paper also presents the most relevant modulation methods developed for this family of converters: multilevel sinusoidal pulse width modulation, multilevel selective harmonic elimination, and space-vector modulation. Authors strongly believe that this survey article will be very much useful to the researchers for finding out the relevant references in the field of topologies and modulation strategies of multilevel inverter.

Load forecasting techniques and methodologies: A review

Abstract: Electricity demand forecasts are extremely important for energy suppliers and other participants in electric energy generation, transmission, distribution and markets. Accurate models for electric power load forecasting are essential to the operation and planning of a utility company. Load forecasts are extremely important for energy suppliers and other participants in electric energy generation, transmission, distribution and markets. This paper presents a review of electricity demand forecasting techniques. The various types of methodologies and models are included in the literature. Load forecasting can be broadly divided into three categories: short-term forecasts which are usually from one hour to one week, medium forecasts which are usually from a week to a year, and long-term forecasts which are longer than a year. Based on the various types of studies presented in these papers, the load forecasting techniques may be presented in three major groups: Traditional Forecasting technique, Modified Traditional Technique and Soft Computing Technique.

An overview of SiC power devices

Abstract: Considering the recent global interest in reducing energy consumption, SiC technology is now ready to enable the step to the next plateau for efficiency standards. The reduction in power losses that this technology provides in power conversion systems is enabling a quicker adoption of alternative energy systems, improving existing technology and allowing a reduction in future fossil-fuel consumption. As these devices are further optimized in the coming years we can expect even better performance results. SiC Schottky diodes that are commercially available today and the pending introduction of SiC DMOSFETs will help develop much more efficient next generation alternative energy systems and greatly improve power supply, motor drive and UPS efficiencies. The on-going development of 15 kV SiC IGBTs will enable the more efficient interfaces for Distributed Energy Resources to the electric grid.
