Optimal Energy Distribution with Energy Packet Networks

TL;DR

This paper explores optimal energy distribution in energy packet networks with harvesting and storage, aiming to minimize response time and energy loss through analytical solutions.

Contribution

It introduces an optimization framework for energy distribution in energy packet networks considering harvesting, storage leakages, and workload, providing optimal solutions under fixed harvesting rates.

Findings

Optimal solutions minimize response time and energy loss.

Energy is preferentially sent to idle workstations when harvesting is high.

The model accounts for storage leakages and idle energy losses.

Abstract

We use Energy Packet Network paradigms to investigate energy distribution problems in a computer system with energy harvesting and storages units. Our goal is to minimize both the overall average response time of jobs at workstations and the total rate of energy lost in the network. Energy is lost when it arrives at idle workstations which are empty. Energy is also lost in storage leakages. We assume that the total rate of energy harvesting and the rate of jobs arriving at workstations are known. We also consider a special case in which the total rate of energy harvesting is sufficiently large so that workstations are less busy. In this case, energy is more likely to be sent to an idle workstation. Optimal solutions are obtained which minimize both the overall response time and energy loss under the constraint of a fixed energy harvesting rate.
