摘要：

输配电价改革对于省级电网前端规划提出了更高要求。基于输配电价改革要求,构建省级电网不同类型规划投资项目单位产出效率效益指数模型,并综合考虑历史规划项目优选的叠加影响、各类项目相对重要度和规划目标约束,构建基于效率效益指数模型的省级电网投资分配和优选模型,基于风险指数模型剖析影响效率效益指数的关键不确定性指标。通过与传统方法及输配电价核心监管参数进行比较,验证了方法的有效性。结果表明,提出的方法在新形势下评估各类项目效率效益合理性方面优于传统方法,且电量、资产是电网投资效率效益指数主要影响指标,与输配电价监管核心参数一致,此外,电网公司应重点关注满足新增负荷、加强网架和变电站配套送出类项目。

Abstract:

The reform of transmission and distribution prices puts forward higher requirements for the front-end planning of the provincial power grid. Based on the requirements of transmission and distribution price reforms, a unit output efficiency benefit index model for different types of planned investment projects of provincial power grids is constructed, by comprehensively considering the superimposed impact of historical planning project selection, the relative importance of various projects and planning target constraints. The provincial grid investment allocation and optimization model based on the efficiency benefits index model is constructed. And based on the risk index model, the key uncertainty indicators that affect the efficiency benefit index are analyzed. The effectiveness of the method is verified from two aspects compared with traditional methods and core supervision parameters of transmission and distribution prices. The results show that the proposed method is superior to the traditional method and electricity and assets are the main indicators of the power grid investment efficiency benefit index, which are consistent with the core parameters of transmission and distribution price supervision. In addition, power grid companies should focus on projects such as meeting new loads, strengthening infrastructure and supporting transmission from substations.

Key words: reform of transmission and distribution price, planning, efficiency benefit model, risk index
