Abstract
It is a problem that the connection of distributed energy to the power grid, which also affects the power quality. After the distributed energy is connected to the power grid, the power flow calculation of the distributed energy cannot be calculated such as that of the traditional power grid, and therefore, it is necessary to consider the situation with distributed energy access based on traditional power flow calculation. In this paper, considering the static characteristics of the load voltage of constant power, constant current, and constant impedance, the power flow calculation models of different types of distributed energy sources are established after being connected to the grid. Through the establishment of the model of the high-voltage distribution network in the Huanghua area of Qinghai, the power quality of the power grid in the light and heavy load states of the distribution network when the power station is connected and the power station is not connected is analyzed, which further illustrates that the model is suitable for different Power flow calculation problems for types of distributed energy.
