The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscil‌la‌t‌i‌o‌ns in a power system to improve power system stability. The add‌i‌tion of a supplementary controll...

The supplementary control of the UPFC can significantly enhance the damping of interconnect power systems. However, the conventional controller designed based on a linearized model cannot provide adequate damping signal over a wide range of operation points. In this paper, a fuzzy controller is designed as the substitute of the conventional controller. The parameters of the fuzzy controller are...

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...

Several processes have been initiated for the development of technical concepts, guidelines and common requirements of HVDC Grid Systems. For implementing extended HVDC Grid Systems on a multi-vendor basis consolidated and agreed functional requirements for equipment and solutions are needed. Providing such requirements is the role of international standardisation bodies. With the primary focus...

Due to cost effectiveness and less electrical fault hazards, the HVDC transmission is more suitable for long distance power transmission than that for the conventional AC transmission system. Moreover the utilization of power electronics has made HVDC technology competitive and reliable in comparison to HVAC system. The controlling mechanism of the DC link (either monopolar or bipolar) is the m...

This paper proposes a fuzzy logic controller (FLC) based variable resistive bridge type fault current limiter (VR-BFCL) to minimize the impact of faults on voltage source converter high direct (VSC-HVDC) systems. FLC for VR-BFCL is developed dynamically insert appropriate limiting resistance during contingencies maintain currents within acceptable limit. The proposed effectively provides duties...
