In the distribution system, energy storage system can be used to stabilize load fluctuations, while there is a key problem of how to optimize the allocation of energy storage capacity and energy storage converter power. In this paper, the time-series Gaussian distribution model is used to describe the load with power fluctuations. When the load exceeds the sum of the power of the power supply and ...Show More
When there is competition for scarce resources, reserving capacity for delay-sensitive stream-oriented sessions, such as voice and video, increases the probability that the network will be able to meet the sessions' performance requirements. Mobile wireless networks not only exhibit limited transmission capacity but also frequent connectivity changes, and hence sessions must compete for resources ...Show More
Many alternative systems have been studied based on compact single-RFs for multiple-input multiple-output (MIMO) systems. However, the implementation of such systems has been limited by a lack of robustness in relation to system environment. In this letter, we propose a novel MIMO system based on a repetitive pulse width modulation, which requires a single-RF and switches only, without the need fo...Show More
Resource shortage detection can avoid the phenomenon of abandoned wind and light in distribution network. In order to fix the performance of resource shortage detection on power demand side, a fixed resource shortage detection method considering temporal and spatial correlation is proposed. Using outlier data mining algorithm, the outlier data of power demand side resources are obtained, and the p...Show More
Beamforming (BF) and MIMO (multi-input, multi-output) improve coverage and capacity in radio communication. However, they are applied for different goals. BF is used when the channel rank is low and MIMO when the rank is high. Theoretical MIMO studies concentrate on the radio channel capacity limits and usually ignore the effect of actual antennas. This study shows first bit-error-rate (BER) simul...Show More
Unlike in the US, the level of delay suffered by airlines in the European ATM network is due primarily to airspace congestion. The long lead time associated with technology development, as well as the recruitment and training of controllers, has necessitated that EUROCONTROL pioneer an innovative process of capacity planning covering a five year time horizon on behalf of its Member States. The Eur...Show More

A frame offset assignment policy is proposed for reducing the soft handoff blocking probability. When assigning the frame offsets to the originated calls in a cell, the proposed policy considers the assignment states of the frame offsets of the adjacent cells. By the numerical examples, the proposed policy was shown to greatly reduce the soft handoff blocking probability due to the lack of the fra...Show More
The traditional tie-line generation schedule is entirely based on the electricity transaction, hence it is independent of the generation schedule of local unit, and couldn't be changed by the load. These cause difficulties in resource allocation and safe and stable operation of power grid. Thus, this paper builds three optimal dispatch modes that are suitable for different scenes, whose objective ...Show More
