REAL TIME POWER SYSTEMS SIMULATION LABORATORY

The continuous growing integration of renewable energy sources, the needs for an environmentally friend energy system, the uprising of energy storage solutions and more generally the deployment of the concept of Smart Grids changed completely the context under which power systems are operated nowadays.

Simultaneously, the digitalization of the power system, i.e. the usage of digital solutions in power systems, is also taking place all around the world.

Under this context, and to leverage the application of new products/ solutions, R&D Nester has a Real Time Power System Simulation (RTPSS) Laboratory, providing a unique research and simulation infrastructure to analyze the behavior of different components of the power system.

Housing state-of-the-art equipment and different test tools it is possible to simulate different scenarios of power systems and assess their performance.

The introduction of digital solutions in power systems creates the opportunity for applications of new solutions and the Laboratory is also equipped with testing tools that allow a co-simulation of power system and communication networks.

Different software and hardware solutions for simulation of communication networks running together with power systems simulation solutions offer this possibility.

The vast range of simulation possibilities include Hardware-in-the-loop (HIL) techniques and in addition to the simulation in the Laboratory premises it is possible to have a remote access to some of its functionalities.

KEY BENEFITS FOR PARTNERS

The large spectrum of tests that can be performed in the laboratory provide R&D Nester partners with knowledge and valid solutions under the scope of the different simulation possibilities.

Testing of power systems and communication networks, including not only pure simulation environment but also HIL possibilities are great advantages for testing of new products and solutions.

Grid operators can test the performance of their grids in real time the deployment of automation and protection devices using HIL techniques; Device manufacturers can verify their products functionalities operating in a close tor real world environment, testing their product compliance, amongst many other possibilities.

  • Testing of protection and automation systems;
  • Hardware-in-Loop (HIL) simulations.

Modelling

  • Model verification/validation (e.g. linear elements models - constant parameters transmission lines, pi-circuits; non-linear models - Surge arrester) using field data and event records.

Power systems scenario simulation

  • Studies for the optimal integration of renewable energy sources;
  • Power system transient studies and performance assessment in line with European connection grid codes;
  • Analysis of power system events.

Communications
