In this paper a comprehensive approach is presented to improve power swings damping based on direct Lyapunov method. The approach combines superconducting magnetic energy storage (SMES) system with static synchronous compensator (STATCOM). Considering the energy absorption/injection ability of SMES, in transient states the combination exchanges both active and reactive powers with power system....

We consider the minimization of transmit power subject to rate-demand and resource constraints of a cognitive radio (CR) multi-input multi-output (MIMO) network under the framework of a noncooperative game. With spatial multiplexing over each frequency band, a multi-antenna node controls its antenna radiation directions and allocates power for each data stream by appropriately adjusting its pre...

Recently there has been a signi"cant decline in the degree to which "rms &pass through' changes in costs to prices, a decline that is frequently characterized as a reduction in the &pricing power' of "rms. The decline appears to be associated with the decline in in#ation in many countries. The decline has important implications for monetary policy because it a!ects both forecasts of in#ation an...

Transmission loss allocation in very large networks with multiple interconnected areas or countries is investigated in this paper. The main contribution is to propose a method to calculate the amount of losses due to activity of each participant in the multi area markets. Pricing of cross-border trades in Multi area systems is often difficult since individual countries may use incompatible ...

The replacement of conventional generation sources by DER creates the need to carefully manage reactive power maintaining system safe operation. principal trend is increase volume connected distribution network in coming years. Therefore, microgrid represents an alternative offer management due excellent controllability features embedded DER, which enable effective interaction between and netwo...

due to the increasing cost and environmental impacts of fossil fuel consumption, using the renewable energies in data center has become an important and essential priority. although using renewable energies has less environmental harmful effects, but the high investment needed for their installations as well as their fluctuating power production characteristic, restricts their usage such that m...

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...
