In this work, biogeography-based optimization (BBO) is presented for solving different constrained economic load dispatch (ELD) problems combined with economic emission aspects in power system. Nonlinear characteristics of generators like valve point discontinuities, ramp rate limits and prohibited operating zones are considered in the problem. The simulation results show that the proposed BBO algorithm...
For steady state voltage stability, load margin analysis is one of the efficient procedures. The mathematical modeling of load margin is formulated as an optimization problem considering in-equality constraints-voltage limits and reactive power generation limits of PV buses. Two particle swarm optimization (PSO) techniques namely adaptive PSO (APSO) and Hybrid PSO (HPSO) are developed. In APSO technique,...
This paper presents Craziness Based Particle Swarm Optimization (CRPSO) technique for solving constrained optimal power flow problems in power systems, considering nonlinearities like valve point loading and prohibited operating zones of generators. In this paper, the proposed algorithm has been tested in 26-bus system under various simulated conditions and its solutions are compared to those of simple...
