Abstract
For the study of distributed grid-connected photovoltaic (pv) affect the quality of power distribution network voltage. Application Matlab respectively different access points in the access of distributed photovoltaic (pv) power distribution network, different capacity and power factor to carry on the simulation. Analysis the influence of distributed photovoltaic access to voltage quality. Results show that the closer it gets to the end of the line network position or and the greater the network capacity,the greater the influence of node voltage photovoltaic system. And the nearer the and node location of nodes affected by the more serious. Because of the photovoltaic system itself will absorb a certain amount of reactive power,so shall be the pv systems with a certain amount of reactive power compensation device. In order to meet the demand for reactive power. Thus the power factor of photovoltaic system is close to 1.
