Research on Modeling of New Energy Power Plant Interface Characteristics Based on Computer Power Flow Calculation Model

Abstract

Abstract In view of the adverse effects of wind power and photovoltaics as the representative of new energy power stations’ active power output fluctuations on the security and stability of the grid, a solution to smooth the active power output of intermittent power sources using energy storage systems is presented. In this paper, the boundary coordination equation in the form of implicit function is used to model the coordinated solution of dynamic power flow equations in the whole network. This model can uniformly consider the reasonable distribution of boundary node power balance and unbalanced power among the district grids.
