This paper describes secant method with particle swarm optimization (PSO) for solving the economic dispatch (ED) problem with valve point loading. The ED problem is solved in two stages. The range of output powers near the global optimal solution is determined by the secant method and then the final optimal solution is obtained by PSO. The proposed algorithm has been tested on 3-, 13- and 40-units...
This paper describes secant method combined with particle swarm optimization for solving economic dispatch (ED) problem with prohibited operating zones. Two stages are involved in the proposed approach to solve the ED problem with prohibited operating zones. First, the range of output powers near to the global optimal solution is determined by secant method without considering prohibited zones and...
This paper presents a Particle Swarm Optimization (PSO) based algorithm for optimal flow with generating units having non-smooth fuel costs curves while satisfying the constraints such as generator capacity limits, power balance, line flow limits, bus voltages and transformer tap setting, The conventional loed flow and incorporation of the proposed method using PSO has been examined and tested for...
