The invention discloses a regional energy network multi-time-dimension managing method with multiple fuzzy parameters, and relates to the field of energy. The method includes the steps of dividing optimization management of regional energy into a three-stage optimization scheduling structure of a before-day 24 h plan, an in-day 2 h plan and a real-time 15 min plan according to time dimensions so that the optimum management of the regional energy can be achieved; reasonably arranging an operation scheme and standby plan of controllable resources at different response speeds under different timedimensions so that progressive coordination of the power deviation value can be achieved and scheduling burdens on a regional energy network scheduling center can be reduced, and converting traditional deterministic system constraints into fuzzy chance constraints so that the confidence coefficient of credibility change constraints can be progressively increased and adjacent and renewable energyand system load prediction precision can be gradually improved.
