Congestion Alleviation in Market-Based Power Systems Using Co-Optimization of FACTS Devices and Generation Rescheduling

摘要

This manuscript presents a co-optimization techniques of flexible alternative current transmission system (FACTS) devices and generations rescheduling in electricity market systems. The target is alleviating the operation cost of system and thus increasing loadability under both contingency and normal operations keeping system security. For assigning the optimum places of multiple FACTS devices in deregulated electricity markets considering different operation conditions (normal and emergencies), the absolute difference in locational marginal prices (LMP) among two buses is employed for assigning the candidate lines while voltage security constraint is employed for assigning the candidate buses. The sensitivity technique forms a priority list for reducing solution space. The presented technique is applied on amended IEEE 14 bus.
