Improving transmission network flexibility by FACTS, HVDC and renewable energy integration

Abstract

Electric power grids are undergoing major transformations driven by a growing penetration of renewable distributed generation, electrical vehicles and large-capacity energy storage. These complex challenges are driving the development of innovative solutions to improve grid reliability, efficiency and resiliency. FACTS (Flexible AC Transmission Systems) and HVDC (High Voltage Direct Current) enable economical, more efficient long-distance transmission of bulk power and grid access to distributed energy sources such as offshore wind farms. The study presented here is an attempt to consolidate the western Algeria transmission network by flexible network devices to facilitate the integration of renewable energy and make it more efficient network by improving the quality of the network, namely the voltage quality and power flow quality. The open source simulation tool PSAT(Power System Analysis Toolbox) is used in this simulation study.
