The photovoltaic sector is embarking on a new phase of development. To ensure that photovoltaic power generation systems can prevent islanding effects when connected to the grid, grid-connected photovoltaic inverters are being adjusted and updated in alignment with the “14th Five-Year Plan.”
To ensure that photovoltaic power generation systems can prevent islanding effects when connected to the grid, grid-connected photovoltaic inverters are being adjusted and updated in alignment with the “14th Five-Year Plan.” This is to meet the goals of the energy transition and domestic photovoltaic market demands.
Despite that, islanding detection seems to have nonetheless become a de-facto mandatory feature for grid-connected inverters, mostly driven by US and Japanese standards.
The conditions for islanding to form are also clearly stated in in the context of grid-feeding inverters, namely: The PV system must be producing nearly exactly the power that is required for the load to operate. This is valid for both the active and reactive power flows.
