Grid-tie inverters can be regarded as the main component in both renewable-energy conversion systems and smart grid systems. They can convert renewable energy into power that then can be fed to the utility grid as long as the renewable source exists. For photovoltaic (PV) inverters, solar energy must be there to generate.

possible to use PV inverters to compensate reactive power in systems with different loading conditions and PV integration share index. This is done by comparing PV inverter losses with
In this modern world, the need of renewable energy power generation has grown lot, due to the huge increase in power demand as well depletion of fossil fuels. In smart cities,
In general, PV inverters can provide reactive power during nighttime and during daytime. During nighttime, inverter losses are attributed entirely to the reactive power generation and are generally higher than specific losses due to reactive power flows in the distribution system.
For low and medium load levels, there is no practical possibility for loss reduction. For high loading levels and higher PV penetration specific reactive savings, due to reactive power provisioning, increase and become bigger than additional losses in PV inverters, but for a very limited range of power factors.
For high loading levels and higher PV penetration specific reactive savings, due to reactive power provisioning, increase and become bigger than additional losses in PV inverters, but for a very limited range of power factors. í µí± , for analyzed inverter, as a function of power factor and for different active power output of the inverter.
where are the specific reactive power savings, are the overall power losses when the generated reactive power equals zero, are the power losses when reactive power has been generated and thus inverter’s power factor is below 1, and is the reactive power generated by the PV inverter.
