大家都知道,网络监控中需要传输的视频流的数据量非常庞大(目前2M理论带宽的网络实际中能传几路比较清晰度的视频已非常困难),而且基于监控的特殊性.其传输中还存在安垒性的问题。但是目前的IP网络进入从实验网变成大规模商业化运行... 大家都知道,网络监控中需要传输的视频流的数据量非常庞大(目前2M理论带宽的网络实际中能传几路比较清晰度的视频已非常困难),而且基于监控的特殊性.其传输中还存在安垒性的问题。但是目前的IP网络进入从实验网变成大规模商业化运行几年时间,其安全性、传输速度一直没有达到网络监控的要求。独立铺光纤线、或租借ATM专线等方式虽然能解决部分安全性问题或传输速度问题.但其导致的高昂成本是其普及的最大难题。 展开更多

Consumers' electricity cost keeps increasing over the time in most countries across the world. The main reason is that importing electricity from generation plants far from a load center is relatively expensive, as costs are paid not only for generation but also for energy loss and network use. To this end, it is more economi- cal to use electricity generated by local distributed generations. In order to reduce customers' electricity cost, a new economic dispatch of smart distribution networks is proposed. Economic dispatch of smart distribution network is to meet load demand with the least consumers' electricity cost considering distributed generators, while recognizing all operational limits of generation and transmission facilities in a distribution network. Case study shows that consumers' electricity cost can be reduced by about 200/o through economic dispatch of distri- bution network. Further, generation cost and emission of distribution network are reduced as well. 展开更多
