An intelligent strategy for monitoring and control of a grid independent microgrid having an energy storage module, wind induction generator, and loads is presented in this paper. The goal for intelligent monitoring and control of the microgrid is to have real and reactive power control while regulating line voltage and frequency and thus maximizing the use of renewable resources. First, a conventional...
This paper presents the modeling and analysis of a grid-connected wind energy conversion system (WECS) using PSCAD/EMTDC. The modeled system is characterized and analyzed for validation. An inverter control algorithm for effective power control is also proposed and evaluated, resulting in an efficient active power control that extracts the maximum power from the wind turbine. The controller also controls...
The paper presents an advanced control scheme for a photovoltaic unit (PV) to suitably drive the injection of both active and reactive power into a MV radial distribution grid. Such algorithm allows a decoupled control of active and reactive power by properly adjusting the modulating signals of the PWM interface converter with the grid. A closed loop regulation scheme has been derived and guidelines...
This paper presents a model of the three-phase PWM inverter and a control strategy using dqO transformation to be employed in a grid connected photovoltaic generation system. The proposed system operates as an active filter capable of compensate harmonic components and reactive power, generated by the other loads connected to the system. To control the power between the grid and photovoltaic system...
