Minimum cost solution of photovoltaic–diesel–battery hybrid power systems for remote consumers

Hybrid systems present a new dimension to the time correlation of intermittent renewable energy sources. The paper considers the daily energy consumption variations for winter and summer weekdays and weekends in order to compare the corresponding fuel costs and evaluate the operational efficiency of the hybrid system for a 24-h period. Previous studies have assumed a fixed load and uniform dail...

Battery aging and the Kinetic Battery Model

Batteries are omnipresent, and with the uprise of the electrical vehicles will their use will grow even more. However, the batteries can deliver their required power for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in long lasting applications. Some detailed battery models that describe t...

Battery Properties Battery-driven Dynamic Power Management

0740-7475/01/$10.00 © 2001 IEEE March–April 2001 THE ACTIVITY OF SEVERAL COMPONENTS in a computing system is event-driven. For example, the activity of display servers, communication interfaces, and user interface functions is triggered by external events, and it is often interleaved with long, idle periods. An intuitive way to reduce average power dissipated by the whole system consists of shu...

Collecting battery data with Open Battery

In this paper we present Open Battery, a tool for collecting data on mobile phone battery usage, describe the data we have collected so far and make some observations. We then introduce the fluid queue model which we hope may prove a useful tool in future work to describe mobile phone battery traces. 1998 ACM Subject Classification D.4.8 Queueing theory
