In this paper, a wind energy conversion system based on a cascaded H-bridge multilevel inverter (CHBMLI) topology has been proposed to be used for the grid interface of large split-winding alternators (SWAs). A new method has been suggested for the generation of reference currents for the voltage source inverter (VSI) depending upon the available wind power. The CHBMLI has been used as a VSI and operated...
In this paper, a control strategy based on the sliding mode control is used to achieve robust control of a distribution static compensator (DSTATCOM) which is controlled as voltage source converter for the grid interface of wind turbine-generator system. The DSTATCOM is used to control the voltage of the bus to which it is connected to a balance sinusoid in respect of the harmonic distortions in supply...
In this paper a description of a solar photovoltaic (PV)-micro turbine grid interface using voltage source inverter (VSI) has been given for voltage support and control in rural applications. It is assumed that the availability of power in these areas is poor and unpredictable. In such cases a solar PV-micro turbine hybrid system can be used to complement the existing grid supply to improve its service...
Recently the usage of distribution generation has significantly increased in the electric power distribution system. Wind generation system has potential application for the grid support. The voltage of the direct driven permanent magnet wind generators (PMSG) is variable due to the intermittent nature of the wind energy. Fluctuating voltage and power is of major concern in the converter based grid...
In this paper, a generalized converter based on the cascaded H-bridge converter topology has been proposed to be used for the grid interface applications. This includes application of grid compensation and distributed generation interface to the grid. Basic H-bridge modules can be used to build a suitable three-phase voltage source converter (VSC) topology for any medium voltage distribution system...
