Research on the Impact of Power Electronics in New Distribution Networks

With the massively distributed energy sources such as solar photovoltaics integrated into the power distribution network, the new generation of distribution systems exhibits significant features such as randomness and volatility. For this, it is necessary to study how to reduce the voltage disturbance of the new distribution system. The relevant research is carried out on the perception of the time distribution of voltage disturbance in the active distribution network and an equivalent circuit model of a new power distribution system is constructed in this paper. Using MATLAB to simulate the voltage disturbance caused by the output voltage of the solar panel after receiving different intensities of sunlight, and improve the relevant circuits. From this to the study voltage perturbations over time, and the regularity of the influence of improved voltage disturbance on the voltage of the node. Finally get the impact that power electronics can have on the distribution network.
