摘要(Abstract)：

针对配电网投资分析中存在的投资总额无法实现精确预估、投资分配比例未能实现有效验证等问题，提出纵横向融合的配电网投资分配策略及其验证方法。首先，根据历史年配电网整体规划的单位投资效果确定总投资额；其次，依据项目类型确定不同项目的分配比例，再以供电网格为限将总体投资额分配至各网格；然后，在供电网格内进行项目优选，采用工程量法分解历史完工项目的实际工程量并确定综合单价，估算出目标年各优选项目的具体投资额；最后，汇总得到目标年的总投资额和分配比例。通过算例分析并与主流方法相比较，验证了所提方法的准确性和有效性。
In response to challenges encountered in the analysis of distribution network investments, such as the difficulty in achieving precise estimations of the total investment and the lack of effective validation for investment allocation ratios, a vertically and horizontally integrated distribution network investment allocation strategy, along with its validation method, is proposed. Firstly, the total investment is determined based on the unit investment effectiveness of historical annual distribution network comprehensive planning. Subsequently, allocation ratios for different project types are determined, and the overall investment amount is allocated to various grids within the power supply network. Following this, project optimization is conducted within each power supply grid. The engineering quantity method is employed to decompose the actual quantities of completed historical projects and determine the comprehensive unit price, allowing for the estimation of the specific investment amounts for selected projects in the target year. Finally, the total investment amount and allocation ratios for the target year are obtained. Through case analysis and comparison with mainstream methods, the accuracy and effectiveness of the proposed approach are validated.
