Cyber Physical Distribution System Optimal Planning Considering the Influence of Multi-dimensional Uncertainties

配电信息物理系统(cyber physical distribution system,CPDS)与主动配电系统具有内在一致性,该融合系统的多维不确定性、深度耦合性使其规划问题更为复杂。文中基于配电信息物理系统在规划中的耦合特性分析,建立计及电压控制功能及通信系统随机故障的CPDS规划模型,提出考虑信息系统随机失效和控制失效的CPDS规划框架,通过优化方案形成和方案概率约束指标评价相结合的融合过程进行求解。以分布式光伏并网且具备电压控制功能的改进IEEE-33节点配电系统为例进行仿真验证,验证所提模型和算法的有效性和实用性,并探讨控制参数、光伏渗透率对配置方案和信息系统随机故障对电压合格概率指标的影响,为配电信息物理系统的规划和改进措施提出建议。

Cyber physical distribution system（CPDS） and active distribution system have inherent consistency. The fusion system＇s characteristics of multi-dimensional uncertainties and deep integration make its planning more complex. This paper analyzed the coupling property of CPDS in planning. The planning model of CPDS was implemented with voltage control and random failure in information systems considered. The planning was solved by the combined processes of optimal schemes formation and schemes probabilistic verification. Simulations were conducted in the modified IEEE 33 nodes distribution system. The results verified the effectiveness of the proposed method. The influences of control parameters and photovoltaic penetration on the allocation schemes and stochastic failure in information systems on voltage qualified probability index were included in the simulations. Suggestions were given to the planning and improvements of CPDS.
