The real-world performance of inverters is investigated across their full range of operation, concentrating on harmonic distortion and power factor. The inverters under review are representative of a cross-section of the UK market in terms of price and device quality. They include both voltage and current source converter topologies. The test results are compared against the relevant clauses of the...
This paper presents a study on the implementation of Real-Time Pricing (RTP) based Demand Side Management (DSM) of water pumping at a clean water pumping station in Northern Ireland, with the intention of minimising electricity costs and maximising the usage of electricity from wind generation. A Genetic Algorithm (GA) was used to create pumping schedules based on system constraints and electricity...
We present a vision for photonic circuit simulation within sophisticated EDA-style design flows and the tool development roadmap to achieve it. Our approach aims to deliver highly-usable, predictive capabilities for a variety of use cases, that seamlessly interoperates with 3rd-party, best-in-class design tools.
This paper proposes a probabilistic principal component analysis (PCA) approach applied to islanding detection study based on wide area PMU data. The increasing probability of uncontrolled islanding operation, according to many power system operators, is one of the biggest concerns with a large penetration of distributed renewable generation. The traditional islanding detection methods, such as RoCoF...
The time and space complexities of Markov random field (MRF) algorithms for image segmentation increase with the number of edges that represent statistical dependencies between adjacent pixels. This has made MRFs too computationally complex for cutting-edge applications such as joint segmentation of longitudinal sequences of many high-resolution magnetic resonance images (MRIs). Here, we show that...
