【摘要】：用户对可靠性的不同需求以及用户参与互动是未来智能配电网必须考虑的重要因素,文中研究了用户分级与互动对最大供电能力(TSC)的影响,提出了计及用户分级与互动的TSC模型。首先,分别分析了不同用户级别和用户互动方式与TSC之间的关系;然后建立了用户响应模型,并基于现有馈线互联的TSC模型提出了计及用户分级与互动的TSC模型;最后对2个不同场景的算例进行了计算分析。分析结果表明,签订可中断负荷或紧急需求响应协议的三级用户,在N-1模式下参与互动并削减负荷会影响TSC的大小,且TSC将随用户削减负荷程度的增大而增大,直到达到电网总容量限值为止。所提方法能够计算在计及用户分级与互动条件下的TSC,为日后用户分级互动环境下配电网发挥最大供电能力奠定了基础。
[Abstract]:Different demands for reliability and user interaction are important factors to be considered in the future smart distribution network. This paper studies the influence of user classification and interaction on the maximum power supply capacity (TSC). A TSC model considering user grading and interaction is proposed. Firstly, the relationship between different user level and user interaction mode and TSC is analyzed, then the user response model is established, and based on the existing TSC model of feeder interconnection, a TSC model considering user grading and interaction is proposed. Finally, two examples of different scenarios are calculated and analyzed. The analysis results show that the third level users who sign interruptible load or emergency demand response protocol will participate in interaction and reduce load in N-1 mode will affect the size of TSC, and TSC will increase with the increase of user load reduction degree. Until the total capacity limit is reached. The proposed method can calculate the TSC, under the condition of user grading and interaction, which lays the foundation for the distribution network to exert the maximum power supply capability in the future user hierarchical interactive environment.
