中文摘要:
      讨论高分布式能源(DERs)渗透场景下,通过虚拟电厂(VPP)管理DERs的智能配电网供电可靠性问题。首先提出VPP可靠性管理策略,包括VPP运营管理和DERs分组优化模型。然后在信息物理融合框架下,设计可靠性评估方法,分析该管理策略对供电可靠性的影响。最后通过基于IEEE33节点的改进算例,验证提出的VPP可靠性管理策略和评估方法,得出VPP对DERs的分组协同优化可使系统在故障期间更经济可靠运行,因此是未来提升配电网供电可靠性的重要平台之一。
英文摘要:
      The reliability issues of the smart distribution system are studied when multiple distributed energy resources(DERs)are managed via virtual power plant(VPP). Firstly, a VPP management strategy is proposed for power supply reliability, which includes VPP operation scheme and optimization models for each DER group. Then, reliability assessment method is developed for this cyber-physical power distribution system and the influence of the proposed strategies on power supply reliability is qualified. It is learned from case study based on IEEE 33 bus system that distribution network with faults can operate more economically and reliably via optimal dispatch of VPP. Therefore, VPP is one of the most potential platforms for the improvement of power supply reliability in the future.
