Abstract

The application provides an intra-day tie-line plan adjustment method considering new energy fluctuation, comprising the following steps: obtaining new energy unit intra-day predicted output; when the new energy unit predicted output fluctuates and the regional reserve is insufficient, adjusting the intra-day tie-line plan based on the new energy unit intra-day predicted output and a pre-constructed intra-day plan model; wherein the construction of the intra-day plan model considers a tie-line control penalty term, a unit total cost, power grid stability and regional reserve. When applied to actual examples, the intra-day tie-line plan can be adjusted when the reserve is insufficient, the mutual aid capacity of the interconnected power grid is exerted, and wide-range active reasonable rebalancing is achieved.
