摘要/Abstract

摘要： 针对电网企业在新电改形势下面临的实际挑战和迫切需求，基于传统节点电价机制，分别采用潮流追踪法和邮票法分摊电网建设成本和运维成本，提出了一种计及电网建设成本与运维成本的全成本电价模型。基于全成本电价模型提出了兼顾安全性与经济性的电网规划方案评估流程，并采用IEEE 14和IEEE 33节点系统验证了所提方法的有效性。算例结果表明，所提全成本电价模型能够在纵向实现不同电压等级线路规划方案的评估，在横向实现不同配网投资项目的组合优选，可为电网公司在新电改背景下的投资规划提供量化分析方法和辅助决策工具。

关键词: 节点边际电价, 潮流追踪法, 全成本电价, 电网规划, 方案评估

Abstract: In view of the actual challenges and urgent needs faced by power grid enterprises, a total-cost price model is proposed with consideration construction cost and operation maintenance cost, in which the power flow tracing method and stamp method is used respectively to allocate the power grid construction cost and operation maintenance cost based on the conventional nodal pricing mechanism. Furthermore, an evaluation process for power grid planning scheme is proposed based on the total-cost price model, which takes both security and economy into account, and the IEEE 14 and IEEE 33 bus systems are used to validate the effectiveness of the proposed evaluation method. The numerical simulation results show that the proposed total-cost price model can not only evaluate the power line planning schemes of different voltage classes, but also optimize the investment portfolio of different distribution networks. The research results can provide a quantitative analysis method and decision-making support tool for power grid enterprises to plan power grid investment in the context of new electric power reform.

Key words: locational marginal price, power flow tracing method, total-cost price, power network planning, scheme evaluation
