Study on influence of inserted photovoltaic power station to voltage distributing of distribution network

Grid-connected photovoltaic power station has changed the distribution of transmission power, thus influences the voltage distribution of load node. In accordance with the relevant provisions, grid-connected photovoltaic power stations should not be active participation of voltage regulation, but it grid-connected will have a supporting role for each node voltage. This paper proposes a maximum admission capacity calculation method which could meet voltage constraint conditions, by simulation example result in the law of influence on voltage distribution which a single and multiple photovoltaic power station grid-connected locations, grid-connected capacity, and node type. For distribution network with photovoltaic power plant plan and design to provide a reference.
