Emergency control of power grid based on hybrid particle swarm optimization
2013
When wavelet variation operation is increased on the basis of standard particle swarm optimization algorithm (SPSO), an innovative hybrid particle swarm optimization algorithm (HPSO) is formed. Based on the HPSO, aiming to the UHV power system containing 1000 kV and 500 kV, we can carry out the coordination optimization of emergency control for transient stability problem, here, the transient stability includes transient voltage stability and transient power Angle stability. Then we give a generator tripping strategy table for different UHV power flow section. The proposed HPSO-based approach has a better global convergence property and can obtain a higher quality of the optimal solution. Simulation results in the testing and demonstrating project of UHV power system show the effectiveness of the proposed approach.
