An evaluation method of feeder automation for distribution network considering distributed generation

The accuracy and precision of automation action in feeder automation (FA) system are important factors to ensure the reliability of distribution network. Wide access of distributed generation (DG) introduces a new challenge to the traditional FA evaluation method. Given this background, this paper presents an evaluation method of the FA for distribution network considering DGs. Firstly, the load states during the fault location, isolation and restoration process are elaborately defined and the affecting factors of FA are systematically researched. Secondly, the evaluation indexes of FA with DGs are proposed, including seven evaluation indexes from two aspects of action process and action result, respectively. Subsequently, the comprehensive evaluation method of the action effectiveness for the FA with DGs in the distribution network is improved based on the failure-free evaluation test method. Finally, a FA system with double loop network is employed to demonstrate the effectiveness of the proposed evaluation method.
