International audience ; The chapter examines both the potential and barriers to off-grid energy storage (focusing on battery technology) as a key asset to satisfy electricity needs of individual households, small communities, and islands. Remote areas away from urban facilities where the main electricity grid is either not developed or the grid is ...

Drawing from sensory ethnography, the present multimodal writing—accompanied by photography and digital video—documents and interprets the mobilities of off-grid living on Lasqueti Island, British Columbia, Canada. The data presentation focuses in particular on the embodied experience of off-grid inhabitation, highlighting the sensory and kinetic ...

2010 9th International Conference on Environment and Electrical Engineering, 2010
This paper deals with problems of off-grid power systems, in particular off-grid power systems with wind power plants and photovoltaic systems. The paper describes a hybrid off-grid power system built at the VSB-TUO campus. This system comprises a wind power plant, a photovoltaic system, a battery bank, a control unit and a streetlight as a connected ...

2015 IEEE International Conference on Digital Signal Processing (DSP), 2015
This work addresses the problem of direction-of-arrival (DOA) estimation, where true DOAs are not on the sampling grid when sparse signal recovery concept is adopted. To estimate DOAs exploring its sparse property, a basis is usually required. However, off-grid issue persists even when a large basis is constructed.

Off-Grid Fundamental Frequency Estimation
IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2018In this paper, we propose a gridless method for estimating an unknown number of fundamental frequencies. Starting with a conventional dictionary matrix, containing sets of candidate fundamental frequencies and their corresponding harmonics, a nonconvex log-sum cost function is formed such that it imposes the harmonic structure and treats every ...

One critical aspect of the global transition to a low-carbon energy system is the provision of an adequate level of energy services to a large and growing proportion of humanity. The energy poor, living primarily off any electrical grid, offer a unique opportunity and new markets for a modular concept for energy access.

The chosen area of study is the brick chimney which provided heat, hot water and cooking facilities in the timber houses of Auckland 100 years ago. Demolition of these chimneys is common as adaptive reuse of the older houses of Auckland occurs. The number of chimneys present in four representative streets will be counted, using aerial photography from ...

Harnessing off-grid renewable energy
2013 International Conference on Renewable Energy Research and Applications (ICRERA), 2013This paper explores how to economically harness renewable energy resources that are off-grid or otherwise isolated from customers. Its hypothesis is that under certain conditions, isolated renewable energy resources can be economically harnessed by using unmanned hydrogen-filled airships.
