Applications of Real-Time Simulation Technologies in Power and Energy Systems

Real-time (RT) simulation is a highly reliable simulation method that is mostly based on electromagnetic transient simulation of complex systems comprising many domains. It is increasingly used in power and energy systems for both academic research and industrial applications. Due to the evolution of the computing power of RT simulators in recent years, new classes of applications and expanded fields of practice could now be addressed with RT simulation. This increase in computation power implies that models can be built more accurately and the whole simulation system gets closer to reality. This Task Force paper summarizes various applications of digital RT simulation technologies in the design, analysis, and testing of power and energy systems.

Reactive power control for variable speed wind turbines to low voltage ride through grid code compliance

This paper is dealing with the reactive power management of two kinds of variable speed wind turbine (WT) technologies in order to respect the grid code requirements during voltage dips. Nowadays, the WT systems are asked to fulfil with many grid connection requirements, especially to provide reactive power during dip voltage with the aim of better voltage recovering. Specific controls applied to Double Fed Induction generator WT (DFIG) and Permanent Magnet Synchronous Generator fully interfaced (PMSG) are proposed in this paper to meet with these requirements. The control laws are studied through simulations; results analysis shows their efficiency and their limits.

Real-time simulation of a medium scale distribution network: Decoupling method for multi-CPU computation

The paper proposes a methodology to model and simulate a medium scale distribution network with several feeders in a real-time multi-core environment. Due to the small length of the lines, this type of simulation is still quite challenging especially when several cores are addressed to compute the simulation. Problems of model conditioning for multi-core computing are discussed. Validation results are then presented. The data of the considered medium scale distribution network are related to a real French 20 kV power system. The used realtime simulator is RT-LAB.
