Medium-voltage Distribution Network Prospective Connection Planning Considering Multiple Transformation Scenarios

Abstract

In order to meet the needs of refined grid planning of medium voltage distribution network and improvement of standardization requirements, this paper proposes a prospective wiring optimization model of medium voltage distribution network considering multiple transformation scenarios. Firstly, two types of typical wiring forms of the prospective grid are quantitatively described; Secondly, three types of transformming and planning solutions are classified and modeled. Pareto optimization is used to coordinate the two optimization goals of construction cost and retention of the current grid. Finally, the validity and practicability of the model are verified through the analysis of a numerical example
