1. OverviewMountain distribution networks are equipped with numerous small hydropower stations, most of which are run-of-river stations without regulation capacity. These stations are connected to the same line as electrical loads, bringing certain negative impacts on power grid operation. The most prominent issue among them is the voltage quality problem. During the wet season, small hydropower stations generate electricity to the grid, and the failure to achieve local power balance leads to el
