The solid state transformer (SST) is seen as a proper replacement of the conventional iron-and-copper transformer in the future smart grid . The SST offers several benefits (e.g. enhanced power quality performance or ...
Currently it is widely accepted that the construction of large generation centers is no longer the best option to supply the increment of electric load. High costs related to the construction of new generation centers, ...
With the increasing development of renewable energy sources and their integration into the grid, international standards require next-generation plants to achieve the same levels of reliability and performance as the current ...
Nowadays, the electrical energy sector is currently found in a dramatic changing paradigm, which moves towards an increasing trend in generating power at distribution levels, where electricity is typically consumed, by ...
The installation of power generation systems based on renewable energy sources has been increasing exponentially over the last decades. However, in spite of the well-known merits of such energy sources, the expansion of ...
Power system is undergoing an unpreceded paradigm shift: from centralized to distributed generation. As the renewable-based generations and battery storage systems are increasingly displacing conventional generations, it ...
Distributed Generation (DG) provides an alternative to the Centralized Generation (CG) by means of generating electricity near to the end user of power with the employment of small-scale technologies to produce electricity, ...
This PhD dissertation proposes a new transformer, i.e., the Custom Power Active Transformer, characterized by a specific design of its magnetic circuit and auxiliary windings which allows shunt and series compensation to ...
The irruption of renewable energy sources with power electronics interfaces is transforming power systems. To minimize the possible adverse effects that these generating systems may have on the power grid, transmission ...
In recent years, there have been considerable efforts in the design and development of technologies and techniques for more efficient harvesting of renewable energy resources to meet the ever increasing electric power ...
Most of large scale photovoltaic systems are based on centralized configurations with voltage source converters of two or three output voltage levels connected to photovoltaic panels. With the development of multilevel ...
During the last century, the electrical energy infrastructures have been governed by synchronous generators, producing electrical energy to the vast majority of the population worldwide. However, power systems are no longer ...
