in this paper, a novel compensator based on magnetically controlled reactor with fixed capacitor banks (fc-mcr) is introduced and then power system stability in presence of this compensator is studied using an intelligent control method. the problem of robust fc-mcr-based damping controller design is formulated as a multi-objective optimization problem. the multi-objective problem is concocted ...

with the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

The system of automatic control the reactive power factor enterprise's supply is considered, in which one part transformer substations equipped with adjustable capacitor units, and second not. Its advantage comparison shown, firstly, lower requirements for its error and, secondly, calculation consumer supplier electricity made taking into account ratio energy to active energy. An estimate regul...

The Gini index (GI), GI II, and III are proven to be effective sparsity measures in the fields of machine condition monitoring fault diagnosis, they can reformulated as ratio different quasi-arithmetic means (RQAM). Under this framework, generalized indices (GGIs) have been developed for sparse quantification by applying nonlinear weights GI, another form referred here power function-based I (P...

Quintessence and k-essence have been proposed as candidates for the dark energy component of the universe that would be responsible of the currently observed accelerated expansion. In this paper we investigate the degree of resemblance between those two theoretical setups and find that every quintessence model can be viewed as a k-essence model generated by a kinetic linear function. In additio...

this paper presents a formulation of unit commitment for thermal units integrated with wind and solar energy systems and electrical vehicles with emphasizing on mixed integer nonlinear programming (minlp). the renewable energy resources are included in this model due to their low electricity cost and positive effect on environment. as well as, coordinated charging strategy of electrical vehicle...

since the emergence of power market, the target of power generating utilities has mainly switched from cost minimization to revenue maximization. they dispatch their power energy generation units in the uncertain environment of power market. as a result, multi-stage stochastic programming has been applied widely by many power generating agents as a suitable tool for dealing with self-scheduling...

Till now, different constitutive models have been applied to model the hot deformation flow curves of different materials. In this research, the hot deformation flow stress of API X65 pipeline steel was modeled using the power law equation with strain dependent constants. The results was compared with the results of the other previously examined constitutive equations including the Arrhenius eq...
