Executive Summary The Polarconsult Small-Scale High Voltage Direct Current (HVDC) project seeks to design, develop, and demonstrate 1) small-scale HVDC converters and 2) innovative complementary transmission infrastructure with the goal of reducing costs for applications in rural Alaska. The project is funded by the Denali Commission, and is comprised of three phases. This report provides a sum...

Flexible AC Transmission Systems (FACTS) devices have shown satisfactory performance in alleviating the problems of electrical transmission systems. Optimal FACTS allocation problem, which includes finding optimal type and location of these devices, have been widely studied by researchers for improving variety of power system technical parameters. In this paper, a DIgSILENT-based Discrete Parti...

Transposons are very valuable tools for genetic manipulation. However, the number of transposable elements that have been suitably adapted for experimental use is insufficient and the spectrum of heterologous hosts in which they have been deployed is restricted. To date, only transposons from animal hosts have been utilized in heterologous animal species and transposons of plant origin have bee...

Abstract The high proportion of virtual power plants (VPPs) used for distributed generation may cause problems such as fluctuations and voltage distribution. In contrast, AC/DC hybrid grid has strong transmission capacity due to its information transmission. However, Its structure the location VPP have an impact on consumption system, relationship between them are closely coupled. addition, Und...

This paper is concerned with transient dynamics and stability of an electric power system with dc transmission. Nowadays dc transmission systems are widely applied to conventional electric power systems. However, transient dynamics of ac/dc power systems, affected by active power which flows into dc transmissions, is not entirely understood. In this paper an unsymmetrical swing equation system ...

Abstract: Today's need for transmission capacity is continuously growing. As it is difficult to obtain new rights-of-way, options such as replacing existing ACby DC-lines to maximize the power capability of existing corridors are required. So as to limit land use, overhead transmission lines have been built as multi-circuit AClines on the same structure in many countries. Changing one AC circui...
