Dynamic Harmonic Modeling and Analysis of VSC-HVDC Systems
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
متن کاملOptimal PMU Placement Considering with HVDC Links and Their Voltage Stability Requirements
In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network. However, it is not practical in real networks due to the relatively expensive cost of PMUs and other technical limitations. Optimal PMU Placement (OPP) is an optimization p...
متن کاملSolutions for Smart and Super Grids with HVDC and FACTS
Deregulation and privatization are posing new challenges to high-voltage transmission systems. High-voltage power electronics, such as HVDC (High Voltage Direct Current) and FACTS (Flexible AC Transmission Systems), provide the necessary features to avoid technical problems in heavily loaded power systems; they increase the transmission capacity and system stability very efficiently and assist ...
متن کاملInvestigation of Hybrid Pseudo Bipolar HVDC Performances Supply Power to Passive AC Network
The traditional HVDC plays an important role in the development of power grid. But the traditional HVDC cannot supply power either to entirely passive AC network or to weak AC system. In fact, an entirely passive AC network can be effectively powered through VSC-HVDC. However, the cost of investment in VSC-HVDC is amazingly high due to the limitation of power electronics technology. Based on CS...
