Abstract

Micro-grid access to distribution network brings new challenges to the operation and control of distribution network. Previous studies on micro-grid mainly focus on the micro-grid model, but the research on the operation and maintenance of distribution network with multiple micro-grids is still few. Firstly, this paper studies the operation and maintenance characteristics of distribution network with multiple photovoltaic micro-grids. Then, combined with the situation of a distribution network project in Central China, the operation schemes under normal operation conditions and various fault conditions are proposed. The corresponding solutions of the fault conditions are put forward and tested in the field. The field test results verify the effectiveness of the solutions proposed for the fault conditions, which has a certain guiding significance for the operation and maintenance of the active distribution network with multiple photovoltaic micro-grids.
