Research on the Maximum Penetration Level of Grid-Connected PV in Distribution Network Taking into Account On-Load-Changing of the Transformer

Abstract:

The grid-connected photovoltaic (PV) has series of effects on the distribution network, the effects become increasing with the PV capacity continues to increase, so, the research on the maximum penetration level of Grid-connected PV the power system can accommodate is very important. In this paper, the influences of connecting PV to the distribution network is firstly analyzed, An calculation model is proposed for computing the maximum penetration level of Grid-connected PV to insure every node voltage not beyond limits, taking into account on-load-changing of the transformer and the influences of PV power is completely out of operation. The experimental analysis shows that the proposed calculation model for computing the maximum capacity is feasible and effective.
