In this paper, we investigate the performance of the dynamic allocation of resources between separate cellular networks. We propose a Dynamic Internetworking Carrier Aggregation (DI-CA) framework which involves every network operator releasing some of its exclusive, but excess, spectrum to another network operator for a limited time. We derive the basic condition for which DI-CA can improve the performance...
Aiming at the uncertainty in the process of assessment voltage sag frequency in the distribution network (such as reliability parameters), combined with unascertained mathematics, this paper proposed an unascertained mathematics method to depict the uncertainty of the reliability parameters. Based on the traditional fault location method, a new unascertained mathematics assessment model and an approach...
Under smart grid, a new programming method of friendly power distribution system is proposed in this paper considering the voltage tolerance of customer equipment under short time power quality disturbances. Due to the uncertainty of power quality during the change of power system structure, the assessment of potential cost caused by customers' equipment failures under possible disturbances for different...
Life cycle cost is an important index to measure the economics of an equipment system, however, many existing uncertainties pose great challenges to researchers in this field. In this paper, the relationship between cost and reliability under uncertain circumstances was analyzed, and a tradeoff model considering the uncertainties between the reliability and the cost was presented, in which the uncertainty...
The impact of voltage sags on equipment is usually described by equipment failure probability, and it is in general very difficult to assess and predict because of uncertainties with both the nature of voltage sags at the power supply side and the voltage tolerance level of equipment. By defining the equipment failure event caused by voltage sags as a fuzzy-random event, a fuzzy-random assessment...
