A Virtual Power Plant (VPP) is a network of distributed power generating units, flexible consumers, and storage systems. VPP balances the load on grid by allocating generated different linked units during periods peak load. Demand-side energy equipment, such as Electric Vehicles (EVs) mobile robots, can also balance supply-demand when effectively deployed. However, fluctuation various makes supply challenging goal. Moreover, communication security between aggregator end facilities critical...

Neuromorphic computing systems are an emerging field that takes its inspiration from the biological neural architectures and computations inside mammalian nervous system. The spiking networks (SNNs) mimic real by conveying information through communication of short pulses between neurons. Since each neuron in these is connected to thousands others, high bandwidth required. Moreover, since spike times used encode SNN, very low latency also necessary. On other hand, combination Two-dimensional...

Application-specific architectures with multiple processing cores integrated a three-dimensional Network-on-Chip (NoC) concept can exploit the parallelism inherent within spiking and non-spiking neural networks to provide low latency high-bandwidth communication. One of critical components in these NoC-based is on-chip routing scheme, which allows data be communicated between also off-chip transported cores. In this work, we present low-latency tree-based multicast spike for scalable...
