To improve the phenomenon of wind and light abandonment caused by the high proportion of new energy con-nected to the distribution network,a coupling suppression method for voltage fluctuations in the high proportion of new en-ergy connected to the distribution network based on a power balance model is designed.Realize parameter prediction of wind power and photovoltaic through LSTM network and historical data of high proportion new energy integration into the distri-bution network.Build a power balance optimization model for high proportion new energy integration into the distribution network,balancing the power of the distribution network under the prediction of wind and photovoltaic parameters.Control the driving pulse of the static synchronous compensator to achieve voltage fluctuation coupling suppression.The test results show that in the case of imbalanced two-phase loads,this method quickly achieves voltage stability within 0.02 s;In the case of fluctuating photovoltaic output and imbalanced two-phase loads,this method achieved voltage stability within 0.05 s.
