Design and analysis of an inverter for Grid connected micro PV Power Plant

Abstract

To enhance the performance of photovoltaic technology in addition to the power quality, The inverter grid-related for PV technology was carried out. This thesis is composed withinside the layout of an inverter linked to the grid to deliver electricity to a small a part of the populace of Goma, a town positioned withinside the east of the DRC withinside the province of North Kivu. there may be an actual want to apply renewable electricity assets which include sun electricity to conquer the common load dropping withinside the town. This want has been accentuated withinside the town of Goma given the expanded density of the populace and no matter the actual efforts made withinside the personal area to enhance the delivery of electrical electricity, a massive a part of the populace isn't always electrified, and the contemporary power distribution networks stay alternatively vulnerable or unreliable. Based on a few present-day research at the incremental conductance method, a superior incremental conductance manipulate algorithm was proposed, that can track maximum power point swiftly and accurately. The oscillation phenomenon, which exists close to the maximum power point, was progressed at a high-quality extent, to the efficiency of photovoltaic cells technology electricity. The inverter control device has an advantage in its immoderate speed and flexibility with the resource of the usage of applying advanced control algorithm. And the deliver harmonic current is remarkably reduced. An effective solution is the usage of solar inverters feeding the grid with alternating current may be a real advantage. In this thesis we have got designed and analyzed an inverter, which can be applied to grid connected photovoltaic production. To validate the outcomes of this work, MATLAB / Simulink software program software modified into used for the simulation. The final result got using 500 photovoltaic cells in serial and 1000 in parallel, under the environment temperature of 300K, standard temperature 1000W / m2 , the grid voltage of the selected site 220V , 50Hz , intermediate DC bus voltage 450V , with the simulation time of 0.4s , confirmed that the advanced control system of the grid current inverter, which has an inclination withinside the direction of the sine wave, waits until it reaches the maximum energy factor tracking, similarly, to being able to place an power arbitrary to load or network, at the same time as the control system has correct stability.
