Method for treating three-phase imbalance and carbon emission of power distribution network through participation of demand response

The invention discloses a demand response participated power distribution network three-phase imbalance and carbon emission treatment method. The method comprises the following steps of performing day-ahead load and new energy output prediction; simulating user behaviors to form flexible load power data, and obtaining a user basic load on the basis of the predicted user total load; a flexible load model of the electric vehicle and the air conditioner is constructed by considering load operation condition constraints; constructing a three-phase imbalance index of the power distribution network, and constructing a carbon emission index of the power distribution network based on different energy carbon emission factors; a multi-target optimization model is constructed by fusing the three-phase imbalance treatment target of the power distribution network and the carbon emission reduction target of the power distribution network; and solving an optimization problem by combining a heuristic optimization algorithm w
