Development of BESS Design Plan for Wind Power System Using Short-Term Capacity Factor

Abstract

By comparison with other renewable resources, wind energy penetration has increased significantly in conventional power system. Due to the variability of wind power system, development of wind power system management technologies and compensation devices have been receiving attention in the field of power industries. With storage, the output of the wind farm can be controlled for improving reliability and also having more economic utilization. A new design plan in this paper based on capacity factor for wind system is to consider actual power supply pattern. In this paper, the energy capacity calculation process based on the specific capacity factor of wind farm for micropower system is introduced, and verification processes are performed through PSCAD/EMTDC by using Jeju Island information which is operated in South Korea. The calculation process is considering surplus power which is occurred between generating power and consumption power according to the independent power system operation characteristics and reserve power of the small-scale power system.
