Abstract:In this paper,the method of reactive power optimization of the whole network in the area affected by new energy is studied in depth,including strengthening the reactive power management,voltage adjustment and reactive power optimization of the new energy power station,strengthening the economic operation management of the main transformer,at the same time,adjusting the curve properly and arranging the maintenance plan. Later,the pilot work was carried out in a substation in a certain area. The results show that through reactive power optimization,the voltage of power grid lines is stabilized,the security of power grid operation is improved,and the power grid environment is optimized.
Keywords:new energy;reactive power optimization;voltage adjustment
