Aiming at the bad influence of the solar photovoltaic generation

analyzes the traditionalthree-level reactive voltage automatic control mode

bases on the peculiarity of power grid reactivevoltage balance control according to layer and area and the control theory of classification-hierarchi?cal increasing control for complex control system

puts forward the method of using many reactive pow?er source harmony control technique to solve the power grid voltage fluctuate by the solar photovoltaicgeneration. The analysis result shows that: to establish the harmonious mechanism of solar photovolta?ic generation and the traditional reactive power source is the technique mode with strong feasibility forkeeping the voltage level of power grid including on a large scale solar photovoltaic generation station.
