Power Management Strategies based on Multi-Agent Systems for Portable Devices Equipped with Renewable Power Sources

Abstract

Electronic portable devices present some technological challenges like battery life, providing services, and integration of renewable power supplies. These challenges can be improved using power management based solutions. Power management systems for electronic portable devices are ad-hoc solutions for each device, so solutions are not general enough to be applied to others. A model driven architecture approach is defined. It allows defining a general power management systems solution for portable devices. The general solution is based on agent modelling, which is parameterized, so it allows automatic retrieval of the power management multi-agent system for a particular device giving values to the model’s parameters. Distributed management strategies are based on giving priority to renewable power sources and reducing power spikes when there is not enough power. A laptop equipped with a photovoltaic charger is introduced for simulating power demand and supply in order to discuss power management strategies for reducing electrical consumption.
