Abstract
The loadability enhancement methods usually propose reactive power source installation. In this paper, an efficient method for voltage stability and loadability enhancement without installation of new equipment and extra expense is presented. The main idea in this paper is optimal dispatch of loads in subtransmission substation using distribution network reconfiguration by switching actions in primary feeders. For finding optimal loading, an efficient genetic based search algorithm is proposed. Also the singular value is used as voltage stability index. The proposed method is applied to subtransmission (63 kV) and primary distribution (20 kV) networks of Hormozgan Regional Electric Company (HREC) in Iran with satisfactory results.
