  • Vector control of current regulated inverter connected to grid for wind energy applications

    Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

  • Power Inverter Basics

    Basic knowledge of power inverter Power inverter mainly adopts the PWM at present, controller switch to DC rapidly in a pulse-period to ensure that the DC integral value is equal to the sampling values of AC sine wave at the same time. After filtered, more than 96% sine wave output can be realized. Pulse inverter is self-excited inverter that output voltage is pulse modulation. This kind ...

  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...

  • Take Your Bedroom Off the Grid

    In recent years there has been a growing interest in renewable energy. The problem is that many people cannot afford to implement a complete renewable energy system all at once. As interest grows and renewable energy equipment prices fall, people will not be ready to take advantage unless the industry and non-profits undertake serious public education. Redwood Alliance, an environmental ...

  • Design of single–stage three–phase grid–connected photovoltaic system with MPPT and reactive power compensation control

    This paper proposes a single stage three–phase grid–connected photovoltaic (PV) system topology, it being simpler and more efficient. This includes the modelling of PV module and the power conditioning unit interfacing the PV to the utility grid with proper power flow control. The output of the PV panel is connected to the DC–side of the voltage source inverter for interfacing to the grid. The ...

  • A novel feed-forward and feed-back control of a VSI for variable speed wind-driven PM alternators

    This paper brings out an improved control strategy for an inverter employed to integrate a 3-kW wind-driven permanent-magnet synchronous generator (PMSG) to the utility network. The proposed controller features a feed-back control for enhanced current tracking performance and a feed-forward control for power tracking with varying wind-speeds. The harmonic content of the current fed to the grid is ...

  • Modelling and control of a variable speed wind turbine driving doubly fed induction generator using three–level PWM converter

    The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage ...

  • Programmed PWM to improve power quality in systems with distributed generation units

    Pulse-Width Modulated (PWM) inverters are widely applied in Distributed Generation (DG) units and power quality equipment owing to their excellent performance and flexible control means. Programmed PWM (PPWM), as a special type of optimal PWM strategy, theoretically allows for setting the fundamental and the selected harmonic amplitudes directly to arbitrary values. The algorithms for solving ...
