Research on voltage fluctuation mitigation scheme caused by MW PV substation connections

Voltage fluctuation is easy to be caused by the MW PV substation connection to the power grid due to its intermittent operation characteristics, where disturb the sensitive industry load normal operations. In response to this question, the misoperation of the sensitive loads caused by the voltage fluctuation are analyzed firstly, and then the measures are provided in paper from two side-power grid side or customer side. Six mitigation schemes are proposed with the analysis of the priorities and the disadvantages. The work in paper is helpful to push the healthy development of the MW level PV substation connections to grid.
