Abstract

Aiming at the transient voltage control problem of the receiving power grid under large-scale photovoltaic power supply access, this paper proposes a transient voltage stability control method for the receiving power grid considering the collaborative participation of photovoltaic and energy storage. This paper first analyses the input-output characteristics of the photovoltaic power supply and energy storage system, studies the reactive power regulation capacity of the photovoltaic power supply and energy storage system during operation, and establishes the model of the photovoltaic power supply and energy storage system. After that, the model of transient voltage stability margin and transient adjustable margin of the receiving power grid is established, and the reactive power coordination optimization model of the receiving power grid, in which PV and energy storage cooperate, is also established. By optimizing the reactive power response capability of the receiving power grid, transient voltage support is provided for the power grid. Finally, the feasibility of the proposed method is verified by simulation analysis, and the simulation results show that the proposed method can coordinate the reactive power output of photovoltaic power supply and energy storage and realize the transient voltage stability of the receiving power grid.
