| 摘要: |
| 随着新型电力系统的不断建设，如何科学确定系统消纳新能源所付出的消纳成本以及将消纳成本公平、合理地分摊，是实现电力系统安全、经济运行的关键之一。针对当前新能源消纳成本难以测算与合理分摊的问题，提出了一种计及不同区域电网差异性的新能源消纳成本测算与分摊方法。首先，提出基于储能投资规划的新能源消纳成本全面测算方法，并基于维克里-克拉克-格罗夫斯(Vickrey-Clarke-Groves, VCG)理论，进一步提出综合考虑新能源消纳成本正负替代效益的分摊原则，实现消纳成本的全面测算与初次分摊。其次，提出基于灵活调节能力表征的不同区域电网消纳能力差异量化方法，并提出基于灵活性指标综合评分的消纳成本再分摊方法，使得消纳能力较强区域电网的新能源承担相对更少的消纳成本，分摊结果更为公平、合理。最后，以修改的IEEE 14节点系统和某实际电网为算例进行仿真分析，验证了所提新能源消纳成本测算与分摊方法的有效性。 |

| Abstract: |
| With the continuing construction of the new energy system, how to scientifically determine the absorption costs paid by the system for absorbing new energy and how to apportion the absorption costs fairly and reasonably are key to realizing the safe and economic operation of the power system. In response to the current challenges of measuring and reasonably allocating absorption costs of new energy, a method that takes into account the differences in regional power grids for the estimation and allocation of new energy absorption costs is proposed. First, a comprehensive method for estimating absorption costs of new energy based on energy storage investment planning is proposed. Using the Vickrey- Clarke-Groves (VCG) theory, a principle considering the positive and negative substitution benefits of absorption costs is further introduced to achieve comprehensive estimation and initial distribution of absorption costs. Secondly, a method for quantifying the differences in absorption capacity of different regional power grids based on flexible regulation capability characterization is proposed. Additionally, a method for reallocating absorption costs based on a comprehensive score of flexibility indicators is proposed, allowing regions with stronger absorption capacity to bear relatively lower absorption costs, thus ensuring a fair and reasonable allocation of absorption costs. Finally, the modified IEEE 14-bus system and an actual power grid are simulated and analyzed to verify the effectiveness of the proposed method. |
