| Abstract |
The introduction of new" renewable energy is going on increase with the second plan of the Korean Government "Technology Development, Utilization and Popularization of New·Renewable Energy". In general, it is connected to the power system due to the nature of it"s source characteristics but it"s interconnection operation impacts on the power system planning and operation. The operation schemes of the existing power distribution system are based on the unidirectional power flow, but unidirectional power flow changes to bidirectional power flow due to the interconnection operation of new·renewable energy. It degrade the existing protection coordination system and power quality of the power distribution system Thus, the technical evaluation process of the interconnection of new" renewable energy are necessary. In this paper, the characteristics of the existing automatic recloser and sectionalizer are reviewed and interconnection capacity evaluation method of the DR(distributed resources) in the existing automatic recloser-sectionalizer protective coordination system are proposed. |
