Source-load-storage flexibility resource assessment method considering high-proportion new energy access

The invention provides a source-load-storage flexibility resource evaluation method considering high-proportion new energy access. The method comprises the steps that flexibility requirements and supply are quantified from the node level and the system level respectively, then an evaluation index reflecting system flexibility balance is constructed, and the index considers the limiting effect of space distribution of flexibility resources and line capacity on flexibility power transmission. And finally, constructing an example, and performing flexibility evaluation on the source-load-storage multi-type resource system to verify the effectiveness of the evaluation method. 本发明提供一种考虑高比例新能源接入的源-荷-储灵活性资源评估方法。所述方法包括：从节点和系统层面分别量化灵活性需求和供给，然后，构建反映系统灵活性平衡的评价指标，该指标考虑了灵活性资源的空间分布及线路容量对于灵活性功率传输的限制作用。最后，构建算例，对源-荷-储多类型资源系统进行灵活性评估，以验证所提评估方法的有效性。
