Reliability Evaluation in Modern Urban Distribution Considering Islands Impacts

Article Preview

Abstract:

A growing number of distributed generators have been connected to urban distribution networks in recent years, which brings great challenges to the traditional reliability evaluation of the distribution grids. Island is a new kind of operation mode of the city grid. In consideration of the importance factor of system load, establish the model of island taking the maximum equivalent workload capacity as objective function and heuristic search technology is proposed to solve the problem. According to the island mode of operation, assess the reliability of the network with islands based on equivalent resistance and minimal path, which have certain instructive significance to the improvement of reliability of the modern urban distribution nets.
