中文摘要:

电改对输配电价核算提出了严格要求，实现双碳目标又需要提高分布式能源发电上网配套工程投资比重，双重压力下的电网投资策略如何影响输配电价亟待研究。通过对影响电网投资的主要参数进行差异化分析，包括投资规模有效性、投资结构和投资时序，基于系统动力学平台构建差异化电网投资与输配电价联动模型，并基于影响参数设置四种不同的投资场景对输配电价进行测算。算例结果表明，投资约束会导致输配电价核算结果明显小于常规结果，投资规模、投资结构和投资时序的调整都会对输配电价构成一定程度的影响，其中，投资有效性规模变动对输配电价影响程度最大，投资时序影响最小。

英文摘要:

Electric mechanism reform has put forward strict requirements on the accounting of transmission and distribution prices. To achieve the dual carbon goal, it is necessary to increase the proportion of investment in supporting projects for distributed energy generation. How does the power grid investment strategy affect the transmission and distribution price under dual pressure need to be studied urgently. Through differentiated analysis of the main parameters affecting power grid investment, including the effectiveness of investment scale, investment structure and investment timing, a differential grid investment and transmission and distribution price linkage model is constructed based on the SD platform, and four different investment scenarios are set based on the influencing parameters to calculate the transmission and distribution price. The calculation example results show that investment constraints will lead to the calculation result of transmission and distribution price is significantly smaller than the conventional result, and the adjustment of investment scale, investment structure and investment timing will affect the transmission and distribution price to a certain extent. Among them, the efficiency variation of investment scale has the greatest impact on transmission and distribution price, while investment timing has the least impact.
