Nordic Early Warning Early Prevention System

NEWEPS is a Nordic research Project for a more efficient digitalized Power System between Statnett and SvK The Nordic TSOs foresee increasing challenges in the operation of the power system as a result of more variable, renewable power generation, more exchange and changing demand patterns in the future. At the same time, new technology gives us new opportunities to monitor and predict the state of the network in real time, and the ability to initiate automatic response to stabilize critical parameters to avoid system collapse. The system operators will develop new operator-information tools for improved situational awareness and enabling more automatic control to ensure stable power supply in the Nordic region. Thus, NEWEPS - the Nordic Early Warning and Early Prevention System - is planned to be integrated into the companies' operating systems. Our power systems are tightly integrated in the Nordic region, and we want to take advantage of the opportunities digitalization offers. We see great benefit from collaborating and developing a smarter and digital energy sector. The project will be carried out in collaboration with universities, research institutions and the supplier industry. Sintef Energi, NTNU, KTH and RISE are partners.

Statnett and SvK want to develop and demonstrate a common information system for stability monitoring and control applications in the Nordic transmission grid, with main focus on Sweden and Norway. The NEWEPS (Nordic Early Warning Early Prevention System) project will demonstrate a system, which will use and further develop stability monitoring methods already developed in national and Nordic research projects. The demonstation aims to pove that a common industry system for controll and protection of the system stability can be developed. The demonstation will specify the methods for getting better system awareness and new wide area warning and control systems. The NEWEP system will comprise the following characteristics, which require innovative solutions: - The demonstration shall have a modular structure that enables connecting and testing various monitoring and control applications developed by different organisations, e.g. TSOs, universities and reaserch institutes - All interfaces between the modules in the system aims to be standardised in such a way that it is easy to add new assessment methods or applications without changing the core of the system. - The demonstration will include applications for wide area monitoring and indicators for critical system states. The main focus is on indicators for voltage and frequency stability and damping of electromechanical oscillations. - The assessment modules aim to be able to create and identify suggestions for automatic control actions or proposed actions to the control room personnel for improving the system stability. - A coordination module aims to co-ordinate outputs from different assessment modules in order to avoid conflicting controls that may deteriorate the system state. - The system will also develop demonstraition of- and assess visualization methods for control centre personnel to monitor the operation and assist in decision making.
