Economic and emission dispatch using cuckoo search algorithm

Abstract

<p class="Default">The economic dispatch problem of power plays a very important role in the exploitation of electro-energy systems to judiciously distribute power generated by all plants. This paper proposes the use of Cuckoo Search Algorithm (CSA) for solving the economic and Emission dispatch. The effectiveness of the proposed approach has been tested on 3 generator system. CSA is a new meta-heuristic optimization method inspired from the obligate brood parasitism of some cuckoo species by laying their eggs in the nests of other host birds of other species.The results shows that performance of the proposed approach reveal the efficiently and robustness when compared results of other optimization algorithms reported in literature</p>

Solving practical economic load dispatch problem using crow search algorithm

“…Generation limits constraint: The real output power from each generator must be between its minimum and maximum limits as follows [1]:…”

“…Economic load dispatch (ELD) is an essential optimization task in the power system. It represents a basic problem in the power system operation, which objects to achieve the minimum cost of energy requirements while satisfying all the unit and system constraints [1]. In the simplest formulation of the ELD problem, the fuel cost function of the generation unit is represented by a quadratic function, and the valve point loading effects (VPL) are ignored, which have the advantages of being smooth and convex.…”

Modified sub-gradient based combined objective technique and evolutionary programming approach for economic dispatch involving valve-point loading, enhanced prohibited zones and ramp rate constraints

“…/h r for solution times of 150 seconds, 53.80 seconds, 100 seconds, 150 seconds and 31.67 seconds respectively. Therefore, it is quite conspicuous that MSGBCAEP method outperforms the other heuristic methods involving non smooth cost functions, multi-objectives and valve point loading [25][26][27] in terms of total cost rate and solution time as well.…”

Minimize electricity generation cost for large scale wind- thermal systems considering prohibited operating zone and power reserve constraints

“…In this paper, the electricity generation integration of WPs and TPs is studied for the core task of electricity cost reduction. The duty of cost reduction and constraint satisfactory is accomplished by using PSO [23][24], cuckoo search algorithm (CSA) [25,26] and one evaluation-based CSA (OEB-CSA). Among the methods, OEB-CSA is first developed in the paper.…”
