A power conversion interface for a small-capacity photovoltaic generation system (PPGS) is proposed in this paper. The composed of DC–DC converter (DDC), battery pack and buck–boost inverter (BBI). integrated to the store or release energy smoothing fluctuation PPGS. only activated when large change occurs array (PV array). DC power, no matter whether from PV pack, needs be converted into AC by...

DEMO will be a fusion power plant demonstrating the integration into grid architecture of an electric utility grid. The design conversion chain is particular importance, as it must adequately account for specifics nuclear on generation side and ensure compatibility with at all times. One special challenges foreseen pulsed operation, which affects operation entire heat transport chain. This requ...

The equivalent model of modern power system is more and difficult to describe its complex stability characteristics, with the continuous promotion conversion. This paper proposes an improved method consider voltage deviation between side load side. On this basis, margin index derived. Therefore, relationship reactive compensation can be analyzed. Finally, correctness effectiveness are verified ...

This work introduces a new non-isolated buck-boost DC-DC converter. Interleaved configuration of the suggested structure increases the voltage conversion ratio. The voltage rate of the suggested converter can be stepped-up and stepped down for lower values of duty-cycle, which causes to decrease in the conduction losses of the system. The voltage conversion ratio of the recommended structure is...

This paper presents modeling, simulation and control of matrix converter (MC) for variable speed wind turbine (VSWT) system including permanent magnet synchronous generator (PMSG). At a given wind velocity, the power available from a wind turbine is a function of its shaft speed. In order to track maximum power, the MC adjusts the PMSG shaft speed.The proposed control system allowing independen...

nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...
