Differential Protection Modeling of the Randstad 380 kV South Ring High Voltage Cable in ATP - EMTP

Modern transmission power networks consist mainly of High Voltage overhead lines, since the later have proven their high operational reliability. However, technological developments have made it possible to use High Voltage cables, not only in the distribution grids, but also at higher transmission voltage levels. Thus, more mixed configurations...

Coordinated Agent-Based Control for On-line Voltage Instability Prevention

Service interruptions have a significant impact on society and therefore the main objective of power system planning and operation is to ensure that they do not happen. Because voltage instability is one of the dynamic phenomena that may result in a system-wide blackout, this type of stability problem has been an important research topic for...

Effects Future Renewable Installations Will Have on System Synchronous and Synthetic Inertia

As wind and solar displace conventional generators, concerns are growing on the effect these asynchronous generators may have on such frequency stabilization services as primary and inertial response. An investigation into the system inertia of a future European energy scenario that integrates a high percentage of renewables was done using the...

Novel Topology of Saturated-core Fault Current Limiter

Increasing levels of fault currents in utility grids are expected to result in mechanical and thermal overstresses of different power system components. To cope with these increased levels, expensive upgrades and replacements of currently employed Circuit Breakers might be required in the near future. Fault Current Limiters (FCLs) are expected...
