Direct relayed power packet network with decentralized control for reliable and low loss electrical power distribution

Direct relayed power packet network is proposed for reliable and low loss electrical power distribution to consumers. Differing from the power packet networks so far proposed, in this scheme, power packets are not stored at routers but a direct path is established to the destination at each packet transmission. Each path is reserved before the packet transmission following the reservation protocol based on the synchronized QoS routing in data packet networking. Therefore, power losses do no occur by packet processing at routers nor by packet discards caused by packet collisions or overflows at routers. In addition, because of the pure decentralized scheme of the network operation, system reliability of the electrical power distribution is obtained against a partial failure of the network. This reliability is especially desirable from the view point of disaster prevention in urban areas. In this paper, besides the description of the proposed power packet network, its performances are evaluated by computer simulations including the network capacity, and its reliability against a partial network failure.
