This paper presents a multi-criteria selection approach for offshore wind sites assessment. The proposed site selection framework takes into consideration the electricity network’s operating security aspects, economic investment, operation costs and capacity performances relative to each potential site. The selection decision is made through Analytic Hierarchy Process (AHP), with an inherited flexibility that aims to allow end users to adjust the expected benefits accordingly to their respective and global priorities.

Grid connected energy storage systems are regarded as promising solutions for providing ancillary services to electricity networks and to play an important role in the development of smart grids. Thus far, the more mature battery technologies have been installed in pilot projects and studies have indicated their main advantages and shortcomings. The main concerns for wide adoption are the overall cost, the limited number of charging cycles (or lifetime), the depth of discharge, the low energy density and the sustainability of materials used.

High Voltage Direct Current (HVDC) interconnections started to spread across land and underwater becoming longer and more powerful. The advance of this technology makes them the prime option for bulk power transmission in future. While on land the length can reach thousands of kilometres underwater they measure less than 600 km. The constraints but also the future developments must be addressed in order to assess the perspectives of this technology.

The development of a multi-terminal (MT) high voltage DC (HVDC) grid based on voltage source converter (VSC) technology has been envisaged as a key development for harnessing the vast offshore wind production potential of the North Seas. In this paper, market integration of a centrally dispatched MT HVDC Grid based on droop control is examined. Particular emphasis is given on the management of onshore imbalance volumes due to offshore wind power forecast errors.

Fast charging is perceived by users as a preferred method for extending the average daily mobility ofelectric vehicles (EV). The rated power of fast chargers, their expected operation during peak hours, andclustering in designated stations, raise significant concerns. On one hand it raises concerns about standardrequirements for power quality, especially harmonic distortion due to the use of power electronics con-necting to high loads, typically ranging from 18 to 24 kW h.

A smart electricity grid opens the door to a myriad of new applications aimed at enhancing security of supply, sustainability and market competitiveness. Gathering detailed information about smart grid laboratories activities represents a primary need. In order to obtain a better picture of the ongoing Smart Grid developments, after the successful smart grid project survey initiated in 2011, we recently launched a focused on-line survey addressed to organisations owning or running Smart Grid laboratory facilities.

This book focuses on the two intra-regional initiatives created for the development and integration of energy markets: the Energy Community and MedReg.

The Energy Community and MedReg, apart from their common strategic role in providing a much-needed stable regulatory environment for energy markets in their respective reference countries, represent examples of a diverse development of regional energy initiatives. The former is initiated by external factors and is an example of a top-down approach, whereas the latter is a voluntary bottom-up initiative of the countries involved. The way the institutional framework is built is not without consequences on the functioning and organization of the two regional initiatives.

The book assesses these different approaches and their consequences in the framework of the development of the Energy Community and MedReg, with particular reference to their impact on regional integration, energy policy and institutional change. The analysis is enriched with several case studies on the role of independent regulatory agencies, the promotion of renewable energy sources, infrastructure and interconnection development across the Mediterranean basin and the implications of exporting the EU institutional model. This book is aimed at policy makers, institutions, energy companies and academics to provide a better understanding of the economic and institutional eco-system that characterize the Mediterranean area.

Future US and European electricity systems will depend on the harmonious evolution of low- and medium-voltage 'smart' grids with high-voltage 'super' grids. Without care, these two developments could undermine, rather than reinforce, one another.

National decisions and behaviors are strictly interdependent and each of them may affect the whole planet; hence, the harmonization and coordination of the policy are the key issues. This is particularly true in the energy sector, where scarce resources, which are presently unevenly shared by the various nations with the possibility of conflicts arising need to be allocated to keep the pace with economic growth and in a manner compatible with the preservation of the environment. In this paper, we use the concept of “smart energy” as a way to embrace the target to meet commitments to the world's sustainability, and a comparison of the energy policies of two key-world players, the EU and China, is undertaken in this context. A framework for quantitatively assessing the effectiveness of various specific policy tools is proposed. The policies are defined and analyzed with reference to the general goals, the tools to pursue those goals and their outcomes, possibly in a quantitative manner resorting to a set of meaningful metrics.

A smart grid is a system that uses information and communication technologies to integrate, in an intelligent way, all users connected to the electrical power system considering their behaviour and actions. For this purpose, information about the electrical network, such as the current, the voltage or the power, is gathered together over time so that the behaviour of suppliers and consumers can be observed and automatically coordinated. Smart grids are becoming a significant part in the configuration of future electrical power systems. A lot of research has been done on using smart grids to achieve highly efficient and user-friendly electrical power systems. Many new methods have been introduced to solve the difficulties energy providers face when transforming conventional electrical networks into smart grids. These difficulties include the integration of renewable energy and different grid systems at national and international levels due to changes in frequency, voltage and in the synchronisation mechanism.

This paper provides an outline of the European smart grid projects and gives an overview of the current infrastructure and smart grid applications of the Turkish Electricity Production System Operator (EUAS), Turkish Electricity Transmission System Operator (TEIAS), and Turkish Electricity Distribution System Operator (TEDAS). In this paper the feasibility of the further steps required is described and some assessments are made and suggestions given on smart grid developments in general.
