Considering an energy harvesting sensor network, the overall probability of event loss is derived. Based on this result, a variety of harvesting resource allocation schemes (sizing the energy storages and the harvesting devices, under a total cost constraint) are provided. Their performances are verified and compared through simulations.

We propose a variation of harvest-then-consume protocol with low complexity where the harvest and consume phases change when the battery energy level reaches certain thresholds. The proposed protocol allows us to control the possible energy outage during consumption phase. Assuming that the battery is perfect and that the energy arrival is a renewal process, we analyze the duty cycle and the op...

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, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...

The world demands a smart and green future in every sector, which directly corresponds to increases electrical energy demand one way or another. It is unfeasible attain with the present infrastructure. That means more research development required. Future sources should be intermittent, and, addition, sector inwards for distributed generation side control. In such cases, smartest most autonomou...
