Power hardware in the loop simulation of wind farm contribution to grid frequency control

Abstract

This paper aims to evaluate experimentally the capability of variable speed wind turbine to contribute to primary frequency control. Emphasis on isolated power system is performed by considering the French Guadeloupe island as a technical case study. The experimental work is based on the Power Hardware In the Loop (PHIL) method. A wind farm is emulated by equipments with reduced scale and is connected to a real-time simulator simulating the Guadeloupe power system via a reversible power amplifier. Two different scenarios have been tested. Comparison demonstrates that variable speed wind turbine can provide a significant support to primary frequency control.

Implementation and value of power hardware in the loop testing bed for wind turbines integrated into grid

“…In [7], a power hardware‐in‐loop based testing bed for auxiliary active power control of wind power plants is built, while the simulation error achieved ms level due to employed switch mode amplifier. In [8], wind turbine PHIL configuration is given and the primary frequency control of wind turbine is validated by the PHIL simulation, while little consideration is given to the stability and accuracy of the simulation. Furthermore, the potential of PHIL simulation given insight into grid integration of wind power has been much less explored, as it is a newer and more complex technique than control hardware in the loop (amplification is necessary and stability/accuracy needs to be ensured [9–11]).…”

Controller hardware in the loop approaches supporting rapid prototyping of smart low voltage grid control

“…HIL is used for a wide field of applications, such as wind turbine control [3] or engine control [4], to test developed hardware with simulated models of their target environment. Isermann et al [4] discuss, that the boarder from the simulated to the real component is not strict, but can rather be shifted during the development phase.…”
