Abstract

The invention discloses a flexibility evaluation method and system suitable for new energy access planning. The evaluation method includes the following steps: generating a typical daily scene of a power system; establishing an index including an energy storage regulation capability index and a new energy consumption capability index and the multi-objective function of the power system node flexibility evaluation of the power grid carrying capacity index; construct the constraints of the power system node flexibility evaluation; according to the data of typical daily scenarios, determine to satisfy the constraints and optimize the multi-objective function dispatching scheme of the power system. The present invention utilizes the construction of typical daily scenarios to deal with the uncertainty of the output of flexible resources, and adds the uncertainty to the flexibility evaluation index in the form of scene probability.

Description

technical field [0001] The invention relates to the technical field of flexibility evaluation of new energy access point planning, in particular to a flexibility evaluation method and system applicable to new energy access planning. Background technique [0002] The inherent randomness and volatility of new energy output represented by wind power generation, high proportion of new energy output brings high uncertainty, and brings new problems to grid planning and operation. Specifically, the selection of different access points for new energy units in the grid topology will have different impacts on the responsiveness of power system flexibility resources, new energy consumption capacity, and safe carrying capacity. Therefore, a flexibility evaluation method applied to new energy power generation access is needed to quantitatively analyze the impact of different points in the new energy access network topology to guide the selection of new energy access points.
