Abstract

We consider an interconnected distributed computer system with multiple computation centres (CC) that operate with energy harvesting to improve sustainability. The intermittent energy harvesting is matched with steady demand from the CCs using energy storage (ES), e.g. batteries. Based on energy leakage from batteries, and power losses over transmission lines, we examine whether a centralised or distributed ES system provides the solution that offers the smallest response time to a fixed workload of computer jobs using the Energy Packet Network (EPN) modelling paradigm.
