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 gives a new modified technique for evaluating non-convex economic dispatch (NCED) problem having non-linear, discontinuous cost function. This new particle swarm optimization technique incorporates time varying acceleration coefficients (NPSOTVAC). The highly non-linear cost function due to ramp rate limit, prohibited operating zones and valve point loading effect is considered in th...

Percutaneous heart valve replacement is currently limited to the replacement of pulmonary and aortic valves in a targeted group of patients. Designing a heart valve for mitral valve replacement is further limited by its distinctive anatomical feature, which places a constraint on its range of design options. To overcome such limitations, the objectives of this study were to use computational mo...

Dynamic economic dispatch (DED) deals with the allocation of predicted load demand over a certain period time among thermal generating units at minimum fuel cost. The objective function DED becomes highly complex and nonlinear after considering various operating constraints like valve point loading, ramp rate limit, transmission loss, generation limits. In this study, sine-cosine algorithm has ...

nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. in this paper, a new method i.e. water cycle algorithm (wca) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. wca is used to solve complicate...
