The invention provides a demand response strategy based on node electricity price and with user satisfaction as an optimization objective. The demand response strategy comprises two stages. In the first stage, spatial dimension load demand response is performed by using the highest power consumption satisfaction of a user side of the whole system as an optimization goal; after the load of the first-stage demand response is obtained, the load is substituted into an optimal power flow model involving a wind power field, and a node electricity price is calculated as the first-phase electricity price of the demand response. In the second phase, time dimension load demand response is performed by using the power consumption satisfaction of each node at different time points as an optimization goal; after the second-stage demand response load is obtained, the load is substituted into the optimal power flow model, and a node electricity price is calculated as the second-phase electricity price.
