由于分布式发电和负荷的不确定性和波动性，有源配电网的运行受到多维因素的影响，这些多维因素可以用海量的运行场景来描述。有效、准确地筛选严重受限情景（SRSs）已成为ADN规划的新挑战。本文提出了一种将短时间尺度运行问题与长时间尺度规划问题相结合的双层协同规划模型。在上层，需求响应资源作为一种有效的无组件规划资源，具有容量价格低、能源价格高、合同期限短的特点，与电网和储能系统配置协同优化，实现储能系统下投资成本与运行成本之间的经济权衡。在下层，根据上层的规划方案，对大量的运行问题进行优化，使日常运行成本最小化；通过基于影子价格的场景筛选方法向上层提供SRSs，模拟ADN运营商向ADN规划者反馈规划信息（即运营场景的受限程度）的过程。以浙江省尖山新区62节点配电系统为例，验证了考虑DR资源和srs的双层协调规划模型的有效性。
Due to the uncertainty and fluctuation of distributed generation (DG) and load, the operation of active distribution network (ADN) is affected by multi-dimension factors which are described by massive operation scenarios. Efficient and accurate screening of severely restricted scenarios (SRSs) has become a new challenge in ADN planning. In this paper, a novel bi-level coordinated planning model which combines the short-time-scale operation problem with the long-time-scale planning problem is proposed. At the upper level, the demand response (DR) resource, an effective non-component planning resource characterized by low capacity price, high energy price, and short contract term, is co-optimized with the configuration of lines and energy storage systems (ESSs) to achieve the economic trade-off between the investment cost and the operation cost under SRSs. At the lower level, with the planning scheme obtained from the upper level, massive operation problems are optimized to minimize the daily operation cost; and the SRSs are provided to the upper level through a shadow-price-based scenario screening method, which simulates the planning information (i.e., the restricted degrees of operation scenarios) feed-back process from ADN operators to ADN planners. Case studies on a 62-node distribution system in Jianshan New District, Zhejiang Province, China, illustrate the effectiveness of the proposed bi-level coordinated planning model considering DR resources and SRSs.
