A Hybrid Approach for Secured Optimal Power Flow and Voltage Stability with TCSC Placement
This addresses power grid efficiency and stability for electrical engineers, but it is incremental as it combines existing algorithms.
The paper tackles the problem of optimizing power flow and voltage stability in electrical grids by proposing a hybrid Improved Gravitational Search and Firefly algorithm for optimal placement of TCSC controllers. The result shows superior performance with minimum generation cost and reduced real power losses on an IEEE 30 bus system.
This paper proposes a hybrid technique for secured optimal power flow coupled with enhancing voltage stability with FACTS device installation. The hybrid approach of Improved Gravitational Search algorithm (IGSA) and Firefly algorithm (FA) performance is analyzed by optimally placing TCSC controller. The algorithm is implemented in MATLAB working platform and the power flow security and voltage stability is evaluated with IEEE 30 bus transmission systems. The optimal results generated are compared with those available in literature and the superior performance of algorithm is depicted as minimum generation cost, reduced real power losses along with sustaining voltage stability.
