摘要：可再生能源高渗透率使得交直流配电网面临严重的随机性和波动性,充分挖掘柔性资源调控潜力可以有效地降低可再生能源带来的网络运行风险.针对当前交直流配电网优化调度主要考虑电压源型换流器(VSC)的调控能力,对VSC与柔性资源协同研究不足的问题,提出一种考虑柔性资源多维价值标签的交直流配电网灵活调度方法.首先,考虑柔性资源调控特性差异,构建了包含响应时段、调节能力、调节成本及响应意愿的多维价值标签评估体系,准确全面地评估柔性资源聚合调控潜力范围;其次,以运行成本最小为目标函数,柔性资源多维价值标签为约束,建立交直流配电网两阶段鲁棒日前优化调度模型,并采用嵌套列和约束生成算法(C&CG)及强对偶理论进行求解;最后,通过改进的IEEE33节点交直流配电网仿真结果表明,所提方法能够充分发挥柔性资源的调控潜力和协同能力,同时可有效提高模型求解效率和求解精度.
