| 摘要: |
| 在新能源渗透率持续攀升与极端事件日益频发的双重背景下，新型配电系统建设亟需同步提升新型配电系统对高比例新能源的消纳能力与应对极端事件的弹性。柔性多状态开关(SOP)能够在多场景下实现快速响应与主动潮流调节，已逐渐成为实现上述目标的关键设施。然而，现有面向单一场景的柔性多状态开关配置策略难以满足新型配电系统多场景建设需求，因此提出了一种计及常态场景新能源消纳和极端场景弹性提升的柔性多状态开关配置策略。系统梳理柔性多状态开关在常态与极端场景下的功能特性；通过构建场景集精准刻画常态下新能源出力的波动性和极端事件发生及其影响的随机性，进而建立考虑常态场景新能源消纳和极端场景弹性提升的两阶段优化配置模型，通过逐步对冲(PH)算法实现两阶段优化配置模型的快速求解；以改进IEEE 70节点系统为算例对所提策略进行验证，结果表明所提策略可显著提升新型配电系统新能源消纳能力和系统弹性，且大幅降低全生命周期配置成本，实现综合效益最大化，为新型配电系统中柔性多状态开关的优化配置提供了有效方案。 |

| Abstract: |
| The growing penetration of renewable energy and the increasing frequency of extreme events require the new distribution system to simultaneously enhance the abilities of renewable energy consumption under normal scenarios and resilience under extreme scenarios. Soft open point(SOP) can realize fast response and active power flow regulation across multiple operating conditions, and has gradually become a key infrastructure to achieve these objectives. However, the existing SOP configuration strategies for single scenario fail to meet the multi-scenario construction requirements of new distribution systems. Aiming at this, a SOP configuration strategy considering renewable energy consumption under normal scenarios and resilience enhancement under extreme scenarios is proposed. The functional characteristics of SOPs in normal and extreme scenarios are systematically summarized. By constructing the scenario sets, the fluctuation of renewable energy output in normal scenarios and the stochasticity of extreme events are accurately described, together with their impacts. A two-stage optimal configuration model considering renewable energy utilization in normal scenarios and resilience enhancement in extreme scenarios is established, and the progressive hedging(PH) algorithm is adopted to realize the fast solution of the model. Case studies on the modified IEEE 70-bus system show that the proposed strategy can substantially increase renewable energy consumption and resilience of new power distribution system, and greatly reduce the life-cycle costs, so as to maximize the comprehensive benefits. The proposed strategy provides a practical guideline for the optimal deployment of SOPs in new distribution system. |
