Micro-grid scheduling method and system considering operation uncertainty

The invention discloses a micro-grid scheduling method and system considering operation uncertainty, and the method comprises the steps: constructing an uncertain model of a micro-grid according to the operation data of the micro-grid; generating a plurality of uncertain scenes through a preset scene tree method according to the uncertain model of the micro-grid; constructing a generator set thermal load scheduling model according to the micro-grid operation data; according to the generator set thermal load scheduling model, all the uncertain scenes and a preset scheduling demand, calculation is carried out through a preset random-robust optimization method, and a micro-grid optimal scheduling scheme meeting the preset scheduling demand under each uncertain scene is obtained; and scheduling the operation of the micro-grid according to the optimal scheduling scheme of the micro-grid under each uncertain scene. According to the method, the optimal micro-grid dispatching mode is found through the actual demand o
