Hybridization of Energy Storage Systems for electric transportation by means of bidirectional Power Electronic Converters

This paper deals with the design of a Hybrid Energy Storage System (HESSs) for electric transportation such as Electric/Hybrid Vessel and Electric/Hybrid Train. The association of more than one Energy Storage Systems (ESSs) e.g., batteries which have different dynamics permit to take the advantages of the characteristics of both ESSs obtaining simultaneously a high energy density and high power density. This yields to a decrease in terms of the size of the main ESS and the total cost and an increase in terms of life span. The emulation of the batteries and with required control algorithm for the HESS are proposed. The design and the control of the HESSs is validated with the simulation in MATLAB/SIMULINK® environment and also with the real-time emulation of batteries in a laboratory setup of a HESS. The real-time experimental results have been validated against PC simulations showing full consistency. The setup of the hardware of HESS can be used to test any technologies of batteries, being a low cost solution for testing and benchmarking.Plan de Ciencia Tecnología e Innovación del Principado de Asturias (PCTI), Fundación para el Fomento en Asturias de la Investigación Científica Aplicada y la Tecnología (FICYT), Programa Severo Ochoa de Ayudas Predoctorales para la formación en investigación y docencia del Principado de Asturias, ID BP13-138.

Flexible AC Transmission Systems (FACTS)

A setback arising from the pressure of increasing power transmission and distribution capacity could easily be resolved by expanding the network and/or installing more transmission lines. However, environmental and economic factors oppose the use of this resolution. These factors have engineered the onward research on designing power networks to provide maximum transmission capacity at minimum cost. The aftermath of the continuous research resulted in the use of Flexible AC Transmission Systems (FACTS), which is solely built on power electronics, to increase transmission capacity, improve stability & dynamic behavior of the system and ensure better power quality. This paper will discuss basically the importance of FACTS in our networks, its components, the earliest technology used – Static VAR Compensator (SVC), and the most recent technology used – Unified Power Flow Controller (UPFC).Plan de Ciencia Tecnología e Innovación del Principado de Asturias (PCTI), Fundación para el Fomento en Asturias de la Investigación Científica Aplicada y la Tecnología (FICYT), Programa Severo Ochoa de Ayudas Predoctorales para la formación en investigación y docencia del Principado de Asturias, ID BP13-138

Reactive Power Management for Distributed Generation: Motivation and Solutions

With the growing concerns of economical and environmental issues arising from centralized electrical generation, transmission and distribution (GTD), distributed generation (DG) has become of high interest to help reduce these impacts. However, most machines (electric generators) used in DG are induction motors (asynchronous) which have some limitations that cannot be overlooked. One limitation is the shortage of reactive power needed to maintain the voltage required to deliver active power. Despite this limitation, technical advancements have been made in the use of power electronic converters to obtain reliable and secure operations of power system. Various means of reactive power compensation in DG and its utilization are discussed in this paper.Plan de Ciencia Tecnología e Innovación del Principado de Asturias (PCTI), Fundación para el Fomento en Asturias de la Investigación Científica Aplicada y la Tecnología (FICYT), Programa Severo Ochoa de Ayudas Predoctorales para la formación en investigación y docencia del Principado de Asturias, ID BP13-138
