This paper presents an effective evolutionary method for solve economic dispatch (ED) with units having prohibited operating zones. ED has been widely used in power system operation and planning for determination of electricity prices. ED problem is a non smooth problem when valve point effects of generation units are considered. With addition the valve point effect and prohibited zones in ED p...

Economic dispatch (ED) problem is a nonlinear and non-smooth optimization problem when valvepoint effects, multi-fuel effects and prohibited operating zones (POZs) have been considered. This paper presents an efficient evolutionary method for a constrained ED problem using the new adaptive particle swarm optimization (NAPSO) algorithm. The original PSO has difficulties in premature convergence,...

T his year, on 17 June, the Geneva Protocol, an international treaty prohibiting the use of asphyxiating or poisonous gases and bacteriological methods of warfare, turned 80 years of age. It was fostered in part by a 1918 appeal in which the International Committee of the Red Cross (ICRC) described the use of poisonous gas against soldiers as a " barbarous invention which science is bringing to...

This paper introduces a new hybrid hill-climbing algorithm (HHC) for solving the Economic Dispatch (ED) problem. This algorithm solves the ED problems with a systematic search structure with a global search. It improves the results obtained from an evolutionary algorithm with local search and converges to the best possible solution that grabs the accuracy of the problem. The most important goal...

Pesticide-Application-Manager (PAM) is an internet-based Decision Support System (DSS) which automates important processes in crop protection by using up-to-date ICTtechnologies and integrating data from different public and private sources. PAM focuses in particular on supporting farmers complying with legal buffer zones to water bodies, settlements and other terrestrial elements deserving pro...

Economic dispatch with valve point effect and Prohibited Operating Zones (POZs) is a non-convex and discontinuous optimization problem. Harmony Search (HS) is one of the recently presented meta-heuristic algorithms for solving optimization problems, which has different variants. The performances of these variants are severely affected by selection of different parameters of the algorithm. Intel...

Nowadays, demand response programs (DRPs) play an important role in price reduction and reliability improvement. In this paper, an optimal integrated model for the emergency demand response program (EDRP) and dynamic economic emission dispatch (DEED) problem has been developed. Customer’s behavior is modeled based on the price elasticity matrix (PEM) by which the level of DRP is determined for ...

This paper proposes an improved approach based on conventional particle swarm optimization (PSO) for solving an economic dispatch(ED) problem with considering the generator constraints. The mutation operators of the differential evolution (DE) are used for improving diversity exploration of PSO, which called particle swarm optimization with mutation operators (PSOM). The mutation operators are ...
