The installation of PV plants aims to obtain the maximum benefit of captured solar energy. The different techniques of modeling and control of grid connected photovoltaic system with objective to help intensive penetration of photovoltaic (PV) production into the grid have been proposed so far in different papers.
For large grid-connected PV power stations, the application architecture involves generating power in blocks and connecting it to the grid in a centralized manner [ 2 ]. This entails segmenting the PV sub-array at specific power levels, with PV cell arrays within the sub-array connected through a centralized or serial structure.
1. Working principle of photovoltaic grid-connected inverter When the public power grid is powered off, the power grid side is equivalent to a short-circuit state. At this time, the grid-connected inverter will be automatically protected due to overload.
Grid connected PV systems always have a connection to the public electricity grid via a suitable inverter because a photovoltaic panel or array (multiple PV panels) only deliver DC power. As well as the solar panels, the additional components that make up a grid connected PV system compared to a stand alone PV system are:
