01.10.2012 – The integration of renewable energy sources and the liberalization of electricity markets pose new challenges for the operation of the European power system. Today's electrical transmission system is operated close to its stability limit because network utilization increases, power generation becomes more volatile and grid expansion projects develop slower than expected. In order to maintain the safe and reliable power system operation an advanced dynamic system management is necessary. Modern equipment such as Flexible AC Transmission Systems (FACTS), High-Voltage Direct Current (HVDC) and/or state of the art measurement equipment using advanced information and communication technology (ICT) provide additional flexibility and could be applied to detect and/or to stabilize critical system states. A key concept for modern power system operation is the implementation of Wide-Area Monitoring, Protection and Control (WAMPAC) systems based on this equipment.
