ABSTRACT
ABSTRACT: Utility reliability is an indicator that measures the ability of a utility system to supply customers with electric power and energy with the acceptable quality and in the required quantity without interruption. The service reliability of a county-level power distribution grid is one of the factors that decide the production value of the customers. To improve the reliability of distribution grids, potential ways of improving the reliability level are investigated from the perspectives of reliability constraints, and the effect of TD-LTE penetration on smart distribution grids is examined to provide theoretical basis for improving the intelligence and reliability of county-level distribution grids. First, the average service availability of urban distribution grids in China is reviewed, and a method and an assessment index system for rating the reliability level of a distribution grid is proposed. Next, the TD-LET process is described, with focus on its superiority and application. Finally, after examining the LTE-based access layer communication system framework of distribution grids, a cooperative wireless resource management framework based on quarantine service is proposed. Our results indicate that a TD-LTE-based country-level distribution grid can expect much higher service reliability.
