The invention discloses an orderly charging and discharging scheduling method for electric vehicles, which adopts a Monte Carlo sampling method to randomly sample the network access states of all electric vehicles (EV) in a researched micro-grid region, and determines the responsivity of an orderly scheduling strategy of EV users in the region. In the EV charging and discharging optimization scheduling process, a two-layer optimization scheduling model is constructed, and a corresponding objective function is established. An IGDT method is adopted to simulate uncertainty of EV vehicle schedulable demand response power, a risk avoidance strategy model is constructed, a maximum estimated value of a deviation coefficient is obtained, and model robustness and system risk avoidance capability are improved. And adopting a CDO algorithm to optimize robust factors in the risk avoidance strategy model. And finally, performing fuzzy normalization processing on an objective function in the two-layer optimization model, and solving the two-layer optimization scheduling model through a PO algorithm. According to the method, the net load peak-valley difference fluctuation in the micro-grid region can be reduced, the comprehensive power utilization cost of the EV user is controlled, and the system stability and the working efficiency are improved.
