Book Description :

"A reliable modular DC-DC converter that is well-suited to the MVDC grid applications is presented in this dissertation. This converter benefits from zero current turn-off and soft turn-on switching. Each power module is designed and controlled such that it employs two small film capacitors for transferring the power from the input to the output. This feature eliminates the need for electrolytic capacitors that have high failure rates. Furthermore, each power module is configured as an isolated converter, using an integrated high frequency transformer. Each power module in the proposed modular converter sees only one semiconductor on the conduction path to transfer energy from the input to the link capacitors or from the link capacitors to the output, which results in relatively low conduction losses. Another advantage of the proposed converter is the possibility of having bidirectional flow of power. The zero current turn-off feature in the proposed converter allows using any type of active switches, even Silicon Controlled Rectifiers (SCRs), which are naturally commuted switches. SCRs have numerous advantages over the other power switches, including higher voltage ratings and current ratings, lower power losses, lower cost, and higher reliability, which are all of particular importance in the MVDC grid application. The main limitation of SCRs is that they have natural commutation and cannot be turned off with gate signals. The approach employed in this dissertation enables the use of SCRs in the proposed modular DC-DC converters. The input and output terminals of the power modules can be connected in series or in parallel to form modular converters that facilitate sharing voltage or current in high power applications. In this dissertation, an input-parallel output-series (IPOS) modular configuration is considered to increase the voltage blocking capability at the output and handle high currents at the input of the converter. The dissertation studies the principles of the operation of this converter and presents its design procedure. Also, a modified topology for reducing the number of inputs switches is proposed. Multi-port configurations that allow having several independent input sources in this modular DC-DC converter are presented in this dissertation. In addition, a brief comparison between the proposed topology and a dual active bridge (DAB)-based modular converter, which is the most common DC-DC converter topology used in MVDC grid, is carried out. In addition, the performance of the proposed modular converter is evaluated through simulations and experiments"--Author's abstract.

Book Description :

The utilisation of renewable energies is not at all new; in the history of mankind renewable energies have for a long time been the primary possibility of generating energy. This only changed with industrial revolution when lignite and hard coal became increasingly more important. Later on, also crude oil gained importance. Offering the advantages of easy transportation and processing also as a raw material, crude oil has become one of the prime energy carriers applied today. Moreover, natural gas used for space heating and power provision as well as a transportation fuel has become increasingly important, as it is abundantly available and only requires low investments in terms of energy conversion facilities. As fossil energy carriers were increasingly used for energy generation, at least by the industrialised countries, the application of renewable energies decreased in absolute and relative terms; besides a few exceptions, renewable energies are of secondary importance with regard to overall energy generation.

Book Description :

This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location. Thus, after a brief description of concepts related to wind power and several subsea cable modeling options, an offshore wind farm is modeled and its parameters defined to use as a base case. Upon this base case, several analyses of the key aspects of the connection infrastructure are performed. The first aspect to analyze is the management of the reactive power flowing through the submarine cable. Then, the undesired harmonic amplifications in the offshore wind farms due to the resonances and after this, transient over-voltage problems in the electric infrastructure are characterized. Finally, an offshore wind farm connection infrastructure is proposed in order to achieve the grid code requirements for a specific system operator, but not as a close solution, as a result of a methodology based on analyses and simulations to define the most suitable layout depending on the size and location of each offshore wind farm.

Book Description :

This book offers a vision of the future of electricity supply systems and CIGRE’s views on the know-how that will be needed to manage the transition toward them. A variety of factors are driving a transition of electricity supply systems to new supply models, in particular the increasing use of renewable sources, environmental factors and developments in ICT technologies. These factors suggest that there are two possible models for power network development, and that those models are not necessarily exclusive: 1. An increasing importance of large networks for bulk transmission capable of interconnecting load regions and large centralized renewable generation resources, including offshore and of providing more interconnections between the various countries and energy markets. 2. An emergence of clusters of small, largely self-contained distribution networks, which include decentralized local generation, energy storage and active customer participation, intelligently managed so that they operate as active networks providing local active and reactive support. The electricity supply systems of the future will likely include a combination of the above two models, since additional bulk connections and active distribution networks are needed in order to reach ambitious environmental, economic and security-reliability targets. This concise yet comprehensive reference resource on technological developments for future electrical systems has been written and reviewed by experts and the Chairs of the sixteen Study Committees that form the Technical Council of CIGRE.
