Abstract: Load shedding is a critical issue in power system especially under restructured electricity environment. Load shedding in reregulated power systems associated with security and reliability is investigated. This paper presents an efficient and reliable evolutionary based approach to reveal the optimal load shedding scheme considering voltage stability. System operators can predict the location and the amount of load shed to avoid a voltage collapse. For this purpose minimum eigen value of load flow Jacobian has been selected as proximity indicator. A computational algorithm for minimum amount of load shedding has been evaluated using Differential Evolution. Proposed methodology has been implemented on IEEE 14 bus system. The obtained results show the effectiveness of the proposed methodology in implementing the optimal load shedding to avoid voltage collapse under non-correction state.
Keywords: load shedding, voltage stability, proximity indicator, differential evolution.
