Abstract

The uncertainty and intermittent characteristics of the output of new energy power sources make the output of grid connected power sources change frequently. With the expansion of the scale of the grid-connected power, the output change of the new energy will affect the distribution of the power flow in the grid, so that the voltage of the system will fluctuate. Aiming at the current large-scale wind turbine and photovoltaic power station new energy power supply connected to the grid, this paper builds the system voltage regulation model, studies the voltage stability of the system, and further proposes measures to suppress the voltage fluctuation of large-scale wind turbine and photovoltaic power station new energy plant station access system based on the engineering practice. This paper studies the stability of transient voltage of power grid by different operation modes of new energy plant station access system.
