In the restructured electricity markets, transmission usage, usage costs, and loss allocation are critical issues for recovering network embedded maintenance costs from users. However, because of integration flexible alternating current system (FACTS) occurrence power contingencies, this is more complex utility's perspective, as it may cause volatility in costs. work, unified flow controller (U...

With the growing demand of radio resources, maximizing spectrum efficiency becomes increasingly important. Traditional static spectrum allocation lacks effective mechanisms for sharing spectral resources. Through adaptive resource allocation, spectrum agility allows the radio devices to dynamically use the idle spectral band and is becoming increasingly attractive because it can provide a large...

Flexible AC transmission system; Static synchronous compensator (STATCOM); Optimal reactive power dispatch (ORPD); Chemical reaction optimization (CRO); Transmission loss Abstract Optimal reactive power dispatch (ORPD) problem has a significant influence on optimal operation of power systems. However, getting optimal solution of ORPD problem is a strenuous task for the researchers. The inclusio...

In a multimedia code division multiple access (CDMA) system, the network performance depends on the success and efficiency in allocating system resources. The system resources in terms of bandwidth and power should be efficiently distributed to each mobile to guarantee its quality of service (QoS) requirements. In this paper, we propose a received power limited (RPL) power assignment, so that t...

Extending ATM services to the wireless environment is intended to provide quality of service guarantees to multimedia applications. However, provisioning of QoS over the wireless link is made difficult by the fact that the burstiness of the channel and the retransmission mechanism of the data link layer protocol result in a randomly varying transmission rate for the ATM connection. In this pape...

This paper presents a novel spectrum allocation strategy for multiuser terahertz (THz) band communication systems when the to-be-allocated is composed of multiple transmission windows (TWs). explores benefits (i) allowing users to occupy sub-bands with unequal bandwidths and (ii) optimally avoiding using some spectra that exist at edges TWs where molecular absorption loss high. To maximize aggr...
