This paper proposes a novel optimal current given (OCG) maximum power point tracking (MPPT) control strategy based on the theory of power feedback and hill climb searching (HCS) for a permanent magnet direct drive wind energy conversion system (WECS). The presented strategy not only has the advantages of not needing the wind speed and wind turbine characteristics of the traditional HCS method, ...

Tendencies in development of wind power industry including direct-drive small-scale wind power plants and generators have been analyzed. Synchronous generators with permanent magnet excitation for direct-drive wind power turbines are described. Primary magnetic field distribution and effect of armature reaction have been studied for design of a low-speed multipole permanent-magnet synchronous g...

In this paper a novel optimal control strategy for energy management of an off-grid hybrid Stirling engine/Supercapacitor power plant is presented based on preliminary results proposed in [1]. An implementation of the control strategy is performed on a real time target that drives a dedicated testbed with a DC machine reproducing the behaviour of the thermodynamic Stirling Engine. The DC machin...

Two controllers are proposed in this paper. These controllers have been designed and implemented on the rectifier and quasi impedance-source inverter (QZSI) in the wind energy conversion system based on permanent magnet synchronous generator (PMSG). Model based predictive control strategy (MBPC) has been used at the proposed design for both controllers. Control of parameters such as load curren...

This paper proposes a robust finite-time controller (FTC) for permanent magnet synchronous generator (PMSG)-based wind turbine (WTG).
