The invention discloses an independent micro-grid dynamic optimization scheduling method, which comprises the following steps of: 1, establishing a long-period energy matching evaluation and optimization model for an independent micro-grid system, and formulating a diesel oil consumption plan, an energy storage system energy storage plan and a load transfer plan within expectation; comprising the following steps: establishing objective functions about reliable power supply probability, diesel consumption and load transfer amount; setting constraint conditions of an energy storage system, diesel oil consumption and load energy transfer; 2, establishing a day-ahead stochastic optimization model based on scene analysis, and making a micro-grid hourly scheduling plan in the next day; the photovoltaic and load uncertainty is processed through a multi-scene technology, and meanwhile, the scheduling risk cost caused by the photovoltaic and load uncertainty is measured by using the conditional value-at-risk CVaR; the
