This paper presents different 2030 studies results in a pan-European framework. Specific attention is paid to the techno-economic evaluation of the application of HVDC (High Voltage Direct Current) technologies for transmission interconnecting the Italian power system with the South East Europe (SEE) Region. Focus is on the impact and on the benefits that HVDC can provide in the different cases, also...
This paper presents a Probabilistic Load Flow (PLF) procedure that allows the impact of distributed generation (DG) on the transmission system to be assessed. By means of the Monte Carlo technique, several system states are simulated, varying the power injection of DG. The load flow solution is performed by the Newton-Raphson method and a distributed slack bus formulation is adopted, in order to distribute...
The aim of the present paper is that of assessing the role of the transmission system in a liberalized electricity market, pointing out that the presence of transmission capacity limits may influence the market outcomes and above all it may make profitable a strategic behaviour rather than a competitive one by one or more producers. From this point of view, the transmission system development becomes...
The overall purpose of the paper is to suggest a suitable methodology of valuing the reactive power support in a deregulated electricity market from the point of view of Transmission System Operator (TSO). The valorization of the reactive resource available in a grid bus will be determined by means of an Optimal Reactive Power Flow (ORPF) procedure, which pursues both economic and security criteria...
This paper analyzes the impact of a large amount of wind generation on the Italian transmission network. The analysis takes into account the fact that the most suitable sites for installation of wind farms are located mainly in Southern Italy and that the power flows from wind turbines will arise in addition to the existing ones, mainly directed to Central Italy, thus increasing the possibility of...
This paper deals with one of the issues consequent on the recent restructuring of the electricity industry: the lack of coordination between generation and transmission system development. Indeed, in this new environment the planning of these two systems is driven by different objectives, resulting in a possible conflict between economics and security. The nodal index called Weighted Transmission...
Afterwards the energy market liberalization in European countries, the issue of optimal allocation of cross border interchanges has gained a notable importance. The most widely accepted method for the congestion management among several interconnected countries is the ldquodecentralized market couplingrdquo (DCM), which was successfully implemented by the power exchangers of France, Belgium and the...
The problem of cross border interchange and of allocation of exchange capacities between interconnected countries of the European Community has gained an ever increasing importance during the most recent years. The reasons for that are to be found in the existing price gap between different countries as well as in the limited exchange capacity of some interconnection corridors. As a result, the European...
