This paper introduces a new approach for scheduling security constraint unit commitment (SCUC) including wind farms. Because of uncertainty in wind power production, we tried to develop a new method for incorporating wind power generation in power plant scheduling. For this, wind power generation modeled with unit commitment in a non-linear optimization problem and simulated by submitting diffe...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

one of the most important behavioral aspects in relationship among the main members of marketing channel is the issue of power and dependence that here we have looked through the source of power and countervailing power and we have considered reputation independence, sale and profits and marketing role dependence. in this research relationship between the two main marketing channel members in h...

flexible ac transmission systems (facts) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. in this paper, in order to find type, size and location of facts devices in a power system a dedicated improved particle swarm optimization (dipso) algorithm is developed for de...

gmelinoides fasciatus (stebbing, 1899) is a baikal endemic amphipod that has recently become widespread in eurasia. this species accidentally entered the cooling reservoir of the belovo power plant and became successfully naturalised there. this study describes the peculiarities of g. fasciatus distribution in reservoir sites with different thermal regimes and analyses the environmental factors...

The transmission of power using light instead electricity—the so called power-by-light (PBL)—has been around for some decades now. Despite this long history, it has only in recent years when PBL systems have experienced enormous effervescence situations where the direct use electrical energy to electronic equipment is either not possible or recommendable. are smarter solution monitoring and con...

We study the link between lobbying and industrial concentration. Using data for past 20 years in US, we show how increases when an industry becomes more concentrated, using mergers as shocks to This holds true both expenditures on federal well campaign contributions. Results are line with predictions of a model where is akin public good incumbents, thus typically underprovided, while merger sol...
