The Influence of Distributed Photovoltaic Access to Distribution Network on Voltage Profile

Abstract:

The generated photovoltaic located at load center has a significant impact on feeders' voltage profile. Firstly, considering the reactive power and the line reactance, after theoretical calculation and simulation, it is proved that the influence on voltage profile of generated PV access to distribution network has a great relationship with its access position and access capacity; when there are multiple PV access to distribution network, the influence on voltage profile is different when combined capacity and location is different. Then the maximum alternative capacity at each node is calculated. Al last, it is illustrated through simulation that shunt reactor at PV node and inverter controlling can solve the voltage violation problem.
