“…The optimization problem for integrating photovoltaics into regional power grids is generally solved by solving single-objective or multi-objective functions. The implementation and optimization goals of the automatic voltage control system are mainly reflected in economic goals, voltage quality, and voltage stability and safety [11] . The economic goal is mainly manifested as minimizing network losses or minimizing the number of operations of discrete equipment (capacitor banks or transformer taps).…”

The reactive voltage control of conventional substations is mainly realized by adjusting the switching of capacitors or reactors and changing the transformer ratio, which can only be controlled discretely. The PV inverter can carry out continuous reactive power control, and the reactive voltage control strategy of the conventional substation does not consider the reactive power control of the PV. In this paper, the nine-zone diagram control strategy of the traditional substation is used as a reference, and the reactive voltage optimization control strategy of a substation with a photovoltaic power generation system is constructed considering the characteristics that photovoltaic inverter can continuously regulate reactive power. Taking the internal power grid of an enterprise as an example, the simulation analysis verifies the effectiveness of the control strategy, which can ensure that the voltage and power factor of the grid-connected access point are qualified. At the same time, the voltage fluctuation of the grid-connected point can be reduced, and the network consumption can be reduced.
