To ensure safe and reliable operation of power system based on wind energy, usually plant operators should satisfy grid code requirements such as grid stability, fault ride through (FRT), power quality improvement, grid synchronization and power control etc. To satisfy the grid code requirements of wind turbine, usually grid side converter is playing a major role. So in order to improve the operation...
A novel energy-based control strategy to determine the switch functions of the machine-side conveter (MSC) in a doubly-fed wind generator is proposed in this paper. From the energy shaping perspective, a port-controlled hamiltonian (PCH) description for the wind energy conversion system (WECS) is obtained. Based on the description and the enegy- matching equation, the proposed switch functions enable...
This paper presents the development of a 200 kVA and 200 MJ kinetic energy storage system (KESS) prototype, based on a switched reluctance machine to be applied in high speed trains. The main goal is to reduce the electric consumption peaks in a high speed railway substation. Both the reluctance machine design criteria and the power electronic converters solution are presented. The control algorithms...
