Abstract

With the increased penetration of distributed photovoltaic（PV）power in grid

the influence ofdistributed PV on the power quality of distribution grid keeps rising. This paper adopts the equivalentcircuit model of distributed power connecting to distribution grid

through the analysis of the voltagerestriction mechanism

and proposed a comprehensive control strategy of setting up photovoltaic activepower and reactive power value injected to distribution grid moment by moment

realize the goal ofimproving the voltage quality fundamentally and increasing the penetration in power grid. The simulationresults show that this control strategy can suppress the voltage rising very well and improve the quality ofvoltage.
