Differentiated Investment Layout and Benefit Analysis of Power Distribution Network Based on Risk Assessment

Against the backdrop of accelerating the construction of new power systems and the transformation of distribution network investment towards lean and efficient, traditional average and homogeneous investment models are no longer able to adapt to significant differences in regional load characteristics, grid structures, equipment levels, new energy access, and operational risks. These factors result in critical challenges, including inefficient capital allocation, persistent vulnerabilities in weak network segments, and suboptimal comprehensive benefits. This article takes the overall risk control of the distribution network as the core orientation, constructs a five dimensional comprehensive risk assessment system including equipment risk, operational risk, power supply reliability risk, new energy consumption risk, and external environmental risk, and forms a standardized risk level classification method. The risk-oriented allocation model is closely related to planning of power distribution networks and new-energy access.
