Abstract The consensus algorithm is widely used in the microgrid, but it affected by communication of distributed generators. If delay serious, can affect system’s performance and cause instability. To ensure stability microgrid under constraints, aiming at extensive penetration flexible loads transmission network considered, this paper proposes a economic dispatch method based on constraints. ...

In electric power system, the vital topic to be mooted is economic load dispatch (ELD). It a non-linear problem with some unavoidable constraints such as valve point loading and ramp rate constraint. For solving ELD distint methods were devised tried for different supply systems yielding slow convergence rates. To achieve fast convergence, dual objective multi constraint swarm optimization base...

Received Oct 14,2012 Revised Jan 05, 2013 Accepted March 02,2013 In practical cases, the fuel cost of generators can be represented as a quadratic function of real power generation and satisfied constraints for minimizing of fuel cost. Artificial bee colony (ABC) algorithm is used for the optimization of active power dispatch of generating units. The proposed method is able to determine, the ou...

Particle Swarm Optimization and Genetic Algorithm methods are used to solve t...

An efficient and optimum economic operation and planning of electric power generation systems is very important. The basic requirement of power economic dispatch (ED) is to generate adequate electricity to meet load demand at the lowest possible cost under a number of constrains. Genetic Algorithms (GA) represents a class of general purpose stochastic search techniques which simulate natural in...
