A proposal for energy management in an off-grid photovoltaic pumping and irrigation system is presented and evaluated for a specific case study. The system is assumed to be based on off-the-shelf components (photovoltaic panels, battery banks, DC/AC converters, relays, submergible pumps, etc.), with a microcontroller-based energy management system, deciding when to disconnect the load from the ...

In this paper, an experimental fuel cell/battery/supercapacitor hybrid system is investigated in terms of modeling and power management design and optimization. The power management strategy is designed based on the role that should be played by each component of the hybrid power source. The supercapacitor is responsible for the peak power demands. The battery assists the supercapacitor in fulf...

Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...

The aim of this paper is to present the idea and starting points for an innovative facility resource monitoring system, which will be realized in a recently started research project: NoFaRe. NoFaRe’s goal is to enable low cost monitoring of electrical devices in buildings using advanced Non-Intrusive Load Monitoring (NILM) techniques and evaluate its value in facility management based on Buildi...

Bridges are the most important components in expansive transportation networks. And bridge management systems (BMS) have been developed to help government agencies maintain the bridges in their districts. However, bridge management systems vary with the different bridge types and the different management requirements for each maintenance level. The multi-level framework of a set of bridge manag...

In order to reduce building energy consumption, we need a global, accurate view of the building. Many modern buildings have a sensing infrastructure that can be used to do fine-grained accounting and understand the complex interactions between systems and spaces. However, through our experience with an active, campus-wide Building Management System (BMS) system, we observe that BMSs are not wel...

Many countries are using bridge management systems (BMSs) as the main toll for the effective management of their bridges. Although many BMSs contain some forms of life-cycle cost analysis (LCCA), the use of LCCA in bridge engineering is scarce and LCCA has mainly been applied to support decisions related to existing bridges. This paper discuss the need of a BMS with an integrated LCCA tool that...
