Abstract

Quantifying how inverters can affect the grid voltage by active and reactive power changes enables advanced concepts for voltage support. A method for the estimation of the voltage sensitivity in a grid section with distributed PV generation is proposed and compared with analytic calculations. The method relies on the aggregation and evaluation of available voltage and power measurements. The necessity of linearly independent power injections is elaborated and the injection of reactive power pulses is proposed to increase the accuracy of the estimate. The method is validated by simulation and experimental results.
