Synthetic Distribution Grid Generation Using Power System Planning: Case Study of Singapore

摘要

Having grid models of existing power distribution systems can be essential for analysis, research and development of innovative smart grid methods and concepts. However, such models are often not available due to security concerns and confidentiality restrictions. This paper presents a novel approach for generating synthetic distribution grids that correspond to existing power distribution systems. The synthetic distribution grid generation model is defined using a power system planning optimization. The model is developed and structured to fit and utilize publicly available data of consumer demand and location, number of substations and their placement and specifications and estimate pricing of installed equipment. An equally weighted multi-objective cost minimization function of investment and operational costs is defined. To represent the physical constraints of the grid, a convex AC power flow is presented. A case study of the Singaporean power distribution system is shown.
