Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of planning project effect evaluation, and in particular to a planning project implementation effect evaluation method and system. BACKGROUND

[0002] With the continuous deepening of power distribution network construction and reconstruction, the demand for quantitative analysis of the contribution of index improvement after the implementation of planning projects is increasingly urgent, which is the key prerequisite for guaranteeing the investment benefit of power distribution networks and optimizing the layout of subsequent projects, and belongs to the core demand of the planning project effect evaluation field. However, in the actual evaluation work, the existing methods generally rely on single comparison before and after the implementation of the target project, but ignore the interference of external environmental factors on the improvement of the index, which leads to the difficulty in accurately separating the actual contribution of the project itself from the evaluation results, and the inability to objectively reflect the real benefit of the project. In addition, the existing evaluation methods present a polarization in complexity and operability: complex models have strict requirements for data quality and application scenarios, and are difficult to adapt to various planning projects, and the popularization rate is limited; while simple pre-post data comparison lacks statistical rigor, and can only achieve one-sided analysis, and cannot fully and scientifically reflect the implementation effect of the project.
