A modeling methodology to evaluate the impact of temperature on Solar Home Systems for rural electrification
(2018)Solar Home Systems (SHS) have recently gained prominence as the most promising solution for increasing energy access in remote, off-grid communities. However, the higher than standard testing conditions (STC) temperatures ... -
A performance evaluation of several artificial neural networks for mapping speech spectrum parameters
(2020)In this work, we compare different neural network architectures, for the task of mapping spectral coefficients of noisy speech signals with those corresponding to natural speech. In previous works on the subject, fully-connected ... -
A risk-based methodology for defining the time of intentional controlled islanding
(2015-10-05)Power systems are operated close to their stability limits and this increases the probability of cascading outages leading to large-area blackouts. To mitigate these phenomena, intentional controlled islanding (ICI) has ... -
A simple methodology for estimating battery lifetimes in Solar Home System design
(2017)The proliferation of Solar Home Systems (SHS) in recent times hopes to provide an alleviating solution to the global problem of energy poverty. Battery is usually the most expensive but important part of an SHS; it is also ... -
