Energy Packet Networks With Energy Harvesting

Gelenbe, Erol
Ceran Arslan, Elif Tuğçe
We investigate the cooperation among energy prosumers (unified energy provider and consumer) through the energy packet network (EPN) paradigm, which represents both the flow of work that requires energy, and the flow of energy itself, in terms of discrete units. This paper details a stochastic model of EPNs, which is inspired from a branch of queuing theory called G -networks. The model allows us to compute the equilibrium state of a system that includes energy storage units, energy transmission networks, and energy consumers, together with the intermittent energy sources. The model is then used to show how the flow of work and energy in the system can be optimized for certain utility functions that consider both the needs of the consumers, and the desire to maintain some reserve energy for potential future needs.


Energy Conversion Efficiency of Single-Phase Transformerless PV Inverters
Özkan, Ziya; Hava, Ahmet Masum (2013-11-30)
In grid-connected photovoltaic (PV) applications, power semiconductor energy conversion efficiency of PV inverters is one of the major figures of merits to evaluate and compare these systems as the payback ratio of the overall system is tightly related to the energy conversion efficiency and as semiconductor losses comprise the majority of energy losses. In order to wisely choose the PV inverter topology and associated semiconductors, analytic evaluation of semiconductor losses of topologies is required. Fu...
Energy packet model optimisation with approximate matrix inversion
Ceran Arslan, Elif Tuğçe; Gelenbe, Erol (2016-06-21)
The ow of energy in a network of intermittent sources of energy, such as renewables, batteries, and of work such as sensing tasks, communication packets and tasks executed in computer servers, is modeled as an Energy Packet Network. Both tasks for execution and energy flows into the system are random processes. A G-Network is used to model the system where both tasks and data packets, and energy in the form of discrete units, move between energy storage units, network routers and computing servers. This que...
Energy Justice: A Social Sciences and Humanities Cross-cutting Theme Report
Topal, Çağatay; Voyvoda, Ebru; Karababa, Eminegül; Lacey-barnacle, Max (2017-6-01)
Energy justice seeks to embed principles of justice, fairness and social equity into energy systems and energy system transitions. This report gives an overview of emerging research in ‘energy justice’ and explores how ideas within different Social Sciences and Humanities (SSH) disciplines interact with key concepts in this rapidly expanding new field. Focusing on three different disciplines - Economics, Business Studies, and Gender Studies - this report highlights the ...
Microwave Energy Harvesting by using a Broadband Fractal Antenna and a Dual-Band Rectifier
Ozdemir, Huriye; Nesimoglu, Tayfun (2018-11-02)
In this paper, a broadband rectenna for radio frequency (RF) energy harvesting is presented. The proposed rectenna consists of a broadband fractal slot antenna and a voltage doubler rectifier circuit with a novel matching network. First of all, a broadband fractal antenna is proposed, which covers the most frequently encountered frequency bands which are located around 1800 MHz, 2.1 GHz, 2.4 GHz, and 2.45 GHz corresponding to the standards like GSM, UMTS, ISM, and WLAN, respectively. The return loss of the ...
Robust Optimum and Near-Optimum Beamformers for Decode-and-Forward Full-Duplex Multi-Antenna Relay With Self-Energy Recycling
Demir, Ozlem Tugfe; Tuncer, Temel Engin (Institute of Electrical and Electronics Engineers (IEEE), 2019-3)
In this paper, we consider the full-duplex decode-and-forward wireless-powered relaying system, which employs energy harvesting protocol with power splitting. The robust joint optimum relay transmit beamformer and power splitting factor are obtained for the quality of service (QoS)-aware problem for the first time in the literature. The optimum solution is found by analyzing the Karush-Kuhn-Tucker conditions, thanks to the effective reformulation of the problem in an equivalent and simplified manner. In add...
