Impact of Distributed Photovoltaic Grid Connection on Distribution Network Voltage
With the rapid development of new power systems,the penetration rate of distributed photovoltaic grid connection continues to increase.A large number of distributed photovoltaic grid connections will affect the direction of power flow in the distribution network,affect node voltage,and affect the safe operation of the distribution network.To address this issue,firstly,analyze the impact of different locations and capacities on the voltage of the distribution network during distributed photovoltaic access.Secondly,build a simulation model based on a typical IEEE33 node and conduct power flow calculation analysis.Finally,obtain the distribution law of voltage in the distributed photovoltaic grid connected distribution network to ensure the safe and stable operation of the power grid.
