The grid-connected inverter converts the AC generated by solar panels into AC that can be directly divided into the power grid through power electronic conversion technology. Let’s understand the working principle of the photovoltaic grid-connected inverter and its role in photovoltaic power generation system. 1.
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
Grid-tied inverters are the critical element in a grid-tied renewable power system. They’re most widely used in Photovoltaic systems. A photovoltaic solar system is the most efficient and popular form of renewable power. The term grid-tied means that the house is still attached to the local electricity grid.
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.
On the other hand, grid side control is requested to improve power quality and efficiency of inverter to ensure reliable operation. Therefore, grid side controller of solar inverter should meet grid interconnection requirements, provide secure grounding, and power decoupling features.
It is important to mention that the system is always connected to the grid but the grid supplies in parallel with the inverter/solar panels the energy demand of the household. Inverter and grid run in parallel feeding power to the loads. Export to the grid can be controlled from 0Watt to maximum power.
