The present paper focuses on main technical, environmental, and economic features of three types of advanced transmission technologies, currently having a different level of maturity and deployment in Europe. The devices addressed in this paper are the SSSC (Static Synchronous Series Compensator), the VSC (Voltage Source Converter)-HVDC (High Voltage Direct Current) and the GIL (Gas Insulated Line). The aim is to investigate the application of these advanced technologies in the future European power system. Towards this purpose, steadystate modeling is an essential stage; in particular, an original SSSC model is presented and validated. Technoeconomic analyses for implementing SSSC and for comparing VSC-HVDC and GIL in specific applications in the future European power system are then carried out.
Economics of FACTS integration into the liberalised European power system
2007 IEEE Lausanne Power Tech, 2007
In spite of a large bibliography available concerning FACTS (Flexible AC Transmission System) analysis and implementation, a very limited amount of contributions in open literature investigate the economics of these devices. The present paper focuses on the economic implications deriving from the enhancement of transmission transfer capacity by utilizing FACTS devices in liberalised power systems. Particularly, attention has been paid to the UPFC (Unified Power Flow Controller), which has been modelled in an original way for DC load flow studies and inserted in an optimisation algorithm for market solving. Test cases in a European regional power market are also presented. Index Terms-analysis of investments, cost-benefit analysis, DC network model, FACTS, load flow control, optimal power flow, power injection model, transmission planning, UPFC.

Transmission and Distribution Networks: AC versus DC
The fast development of power electronics based on new and powerful semiconductor devices has led to innovative technologies, such as HVDC, which can be applied to transmission and distribution systems. The distribution voltage level is smaller than the transmission one, thus the power electronics are less expensive in distribution. The technical and economical benefits of this technology represent an alternative to the application in AC systems. Some aspects, such as deregulation in the power industry, opening of the market for delivery of cheaper energy to customers and increasing the capacity of transmission and distribution of the existing lines are creating additional requirements for the operation of power systems. HVDC offer major advantages in meeting these requirements.

Advanced transmission technologies in Europe: A roadmap towards the Smart Grid evolution
2011 IEEE Trondheim PowerTech, 2011
The progressive re-engineering of the European power transmission system will involve a spectrum of innovative technologies. Their level of application by Transmission System Operators (TSOs) will vary from one control area to the other, also based on past experiences and today's operation constraints. The present paper introduces a Technology Integration Roadmap, developed within the European research project REALISEGRID, with the aim to analyze the evolution of advanced transmission technologies over the next three decades towards their integration into the European power system. This roadmap is based upon a systemic approach which takes into due account two knowledge elements: the transmission system perspective and the technological perspective. It is organized into high level technology components based on a common long-term vision of the European electricity network by 2030, the critical system challenges driving that vision and the overall benefits expected from the implementation of this spectrum of technologies. The present paper proposes an Action Agenda for the next three decades, with potential integration trajectories including milestones as seen by TSOs and manufacturers respectively.
Improvement of Transmission Capacity by FACTS devices in Central East Europe power system
IFAC-PapersOnLine, 2016
The increased demand for power transfer in combination with environmental and economic issues which set constraints to building new lines, force the implementation of new technologies into the existing system in order to improve its power capability. This paper investigates the use of specific FACTS devices and WAMS systems to maximize total transfer capability generally defined as the maximum power transfer transaction in Central-East-Europe power system. Optimal allocation and control of these devices will be very important for TSO or other power market regulators. Effectiveness, optimal allocation and utilization of phasor measurement units (PMUs) for different types of FACTS devices designed for power flow control and increasing transfer capacity were investigated. Paper also compares the economic aspects of these devices.
