Reactive Power (VAR) Compensation using Photovoltaic (PV) Inverter Assignment

Reactive Power (VAR) Compensation using Photovoltaic (PV) Inverter - Assignment Example The error is sent via PI controller and summed to the grid’s voltage in order in order to get a voltage amplitude equivalent to that of the inverter. Active power generated by the inverter is compared with reference active power signal to produce error. Error passes via PI controller, giving rise to a loading angle. This loading angle is then summed to grid’s voltage phase angle, hence resulting to an increased inverter phase angle. The Phase Locked Loop will still recognize the fundamental positive sequence of the source voltage even at the worst cases scenarios of voltage harmonic distortion.   At these conditions, the active filter absorbs balanced and sinusoidal currents from the source, which are in phase with corresponding fundamental positive sequence of the source voltages. The development of this regulation structure for active power filter is employed when combining with other structures that are to be connected in dc link bus. The structures are static converters that are capable of exchanging active power between an energy source or an energy storage device (capacitor at night). The inverter easily transfers this active power to the grid.   A Power Conditioner with energy storage capability is a viable solution in improving the reliability and the qual ­ity of an electric energy supply. There are several tasks that are performed at a single time, for example current harmonic reduction, smoothing of pulsating loads and reactive power com ­pensation. Moreover, the Power Condioner should work as Uninterruptible Power Supply (UPS) at a short time during interruptions of the grid supply. The Power Compensator is a flexible that is coupled to energy storage device like supercapacitor and battery. At the inverter’s dc side, there is a capacitor that stabilizes proper voltage level for better operation of the inverter that acts current source. The rectifier delivers dc power
