Toughness Analysis and Enhancement Strategy Research of Distribution Network in Extreme Environment

This paper analyzes and evaluates the toughness of the distribution network, and briefly introduces measures to improve the distribution network: First, it briefly analyzes the impact of extreme environment on the distribution network, and proposes the concept of toughness of the distribution network. Then distinguish it from the reliability of the distribution network, select indicators and attributes to measure the flexibility of the distribution network, and build a model of the distribution network components and strong winds. Secondly, from the perspective of strengthening distribution network components, microgrids, and reserve energy to improve the toughness of the distribution network, a brief introduction is given to the distribution network enhancement strategy. Then establish the distribution network toughness evaluation model, and finally use specific calculation examples to conduct the toughness evaluation and analysis of the selected distribution network under extreme environment, and calculate the distribution ratio of the distribution network under normal weather conditions.
