Research on coordinated control strategy of reactive power and voltage in the area of multi-station access of new energy

The large-scale collection and access of new energy leads to voltage exceeding the limit at the grid connection point, which seriously affects the voltage stability of the power grid. This paper studies the reactive voltage characteristics of new energy, and models the regulation capabilities of new energy under different regulation modes. Finally, simulation calculations are carried out for the collection station and related new energy stations of a certain regional power grid. The results show that the constant power control mode can make full use of the reactive regulation capabilities of each renewable energy unit, and its voltage reactive regulation capability has been enhanced. It is the best control mode for the collection and access of multiple stations.
