Lifetime Profit-Maximising Co-optimisation of Multi-Service Stacking for Battery Storage
Yuxin Xia, Frederik Schiele, Yihong Zhou +4
Grid-scale battery energy storage can generate revenue by stacking services across electricity and frequency response markets, yet identifying the lifetime profit-maximising stacki…
Understanding long-term energy use in off-grid solar home systems in sub-Saharan Africa
Rebecca Perriment, Vasco Mergulhao, Volkan Kumtepeli +3
Solar home systems provide low-cost electricity access for rural off-grid communities. As access to them increases, more long-term data becomes available on how these systems are u…
The Impact of Grid Storage on Balancing Costs and Carbon Emissions in Great Britain
Seyyed Mostafa Nosratabadi, Iacopo Savelli, Volkan Kumtepeli +4
Grid energy storage can help to balance supply and demand, but its financial viability and operational carbon emissions impact is poorly understood because of the complexity of gri…
Depreciation Cost is a Poor Proxy for Revenue Lost to Aging in Grid Storage Optimization
Volkan Kumtepeli, Holger Hesse, Thomas Morstyn +3
Dispatch of a grid energy storage system for arbitrage is typically formulated into a rolling-horizon optimization problem that includes a battery aging model within the cost funct…
Lead-acid battery lifetime extension in solar home systems under different operating conditions
Rebecca Perriment, Volkan Kumtepeli, Malcolm McCulloch +1
Solar home systems (SHS) provide low-cost electricity access for rural off-grid communities. Batteries are a crucial part of the system, however they are often the first point of f…
Fast dynamic time warping and clustering in C++
Volkan Kumtepeli, Rebecca Perriment, David A. Howey
We present an approach for computationally efficient dynamic time warping (DTW) and clustering of time-series data. The method frames the dynamic warping of time series datasets as…
