Research on voltage coordinated control strategy of large-scale renewable energy access to grid optimization

With the increasing consumption of traditional energy sources and the destruction of the environment, traditional energy generation cannot meet the development of today's society. Replaced by renewable clean energy, a large number of new energy access to the power grid, but large numbers of unconstrained access to the grid will seriously cause problems with unqualified voltage quality. In this paper, the reactive power demand Q of the grid is determined based on the difference between the measured voltage value and the voltage target value collected at the grid point exceeds the allowable range. And by calculating the SVG reactive power adjustment margin of each new energy power plant. For the adjustment margins of reactive power compensation equipment in each new energy power plant, reactive power distribution is implemented using strategies such as equal ratio or equal margin or priority allocation.
