This paper deals with the experimental validation of a Matlab-Simulink simulation tool of marine current turbine (MCT) systems. The developed simulator is intended to be used as a sizing and site evaluation tool for MCT installations. For that purpose, the simulator is evaluated within the context of speed control of a permanent magnet synchronous(More)
This paper investigates the issues of ensuring global power optimization for cascaded dc–dc converter architectures of photovoltaic (PV) generators irrespective of the irradiance conditions. The global optimum of such connections of PV modules is generally equivalent with performing the maximum power point tracking (MPPT) on all the modules. The most(More)
This paper deals with a generation system based on cross-flow water turbines (CFWTs) operating in a river stream. It is equipped with a permanent-magnet synchronous generator and can feed a power grid or an insulated load through a back-to-back power electronics converter. This paper concerns the control of these two operating regimes with focus on the(More)
This paper presents a two loop optimal control structure for variable speed fixed pitch horizontal axis wind turbines (HAWT) having flexible drive trains. That structure, formed by a low frequency loop and a high frequency loop, is the result of the frequency separation principle adopted in the wind modelling. The optimality of the whole system is expressed(More)
This paper focuses on the control of grid-connected photovoltaic arrays, which are required to provide the maximum of power irrespective of the solar irradiance conditions. The energy provided by the arrays is sent to the single-phased utility grid by means of a two-stage conversion system, composed of a DC-DC boost converter and a DC-AC inverter. The whole(More)
In this paper a power hardware-in-the-loop (PHIL) structure for testing algorithms for the management of power flows in all-electric vehicles is presented. Its complex structure, comprising both real-time simulators and control structures, covers the entire electromechanical power chain. It is based upon real-time platforms (DSPACE and RT-LAB) interacting(More)
Power systems today are undergoing a full mutation, primarily due to the opening of power markets, evolution of technology, exhaustion of natural resources, and dramatic changes in climate. In order to respond to these challenges, countermeasures that leverage power electronic converter technology must be taken at all the levels of the power system:(More)
