Atmospheric contamination with organic compounds is undesired in industry and society because of odor nuisance or potential toxicity. Resistive gas sensors made semiconducting metal oxides are effective the detection gases even at low concentration. Major drawbacks selectivity missing sensitivity toward a targeted compound. Acetaldehyde selected due to its high relevance chemical toxic character. Considering similarity between gas‐sensing heterogeneous catalysis (surface reactions, activity,...
Cascading failures are one of the main mechanisms causing widespread blackouts power networks. Models simulating behavior cascading widely used in literature to understand fault propagation and investigate effective mitigation strategies. However, there is a lack validated models that address specific requirements resilience analysis networks computationally fast converge reliably for very large contingency sizes may occur under extreme events. This article presents novel comprehensive ac...
Accounts of extreme power outages transmission systems suggest the acceleration cascading outage propagation over time and splitting cascade into a slow phase subsequent fast phase. This is significant to network operators, as mitigation actions, such load shedding, can only be effectively applied during During phase, disintegrates too quickly for any manual intervention. To supplement accounts outages, we describe observed smaller more common by analyzing data published one North American...
Hybrid nanostructures have shown increasing potential as a replacement for Si solar cells due to the availability of low-cost material combinations. However, up now, hybrid cells, where photon absorption occurs in semiconducting polymer and charge separation at metal oxide-polymer interface, show limited efficiencies. One limitation is caused by relative low carrier mobility oxide. Here we addressed this issue describe use Sn:TiO2|TiO2 core–shell nanowire array increase charge-carrier core...
Abstract Power outages due to cascading failures which are triggered by extreme weather pose an increasing risk modern societies and draw attention emerging need for power network resilience. Machine learning (ML) is used a real‐time selection process on preventive actions, such as topology reconfiguration islanding, aiming reduce the of failures. Training data obtained from Monte Carlo simulations events. The trained ML‐based decision‐making uses only predictors that readily available prior...
Security concerns have been raised about cascading failure risks in evolving power grids. This paper reveals, for the first time, that risk of failures can be increased at low network demand levels when considering security-constrained generation dispatch. occurs because critical transmission corridors become very highly loaded due to presence centralized dispatch, e.g., large thermal plants far from centers. is revealed this work by incorporating dispatch into assessment and mitigation...
Cascading faults, caused by extreme weather events or other natural hazards, have been reported to be one of the main mechanism causing widespread blackouts power network. A method for preventing propagation cascading faults and thus improving network resilience is intentionally sectionalizing into islands. This paper presents a model simulating evaluates impact islanding on island adequacy using suitable metrics. The islands are created two different approaches, top-down approach based...
Renewable energy like solar power is crucial for the transition to more sustainable supply and use in modern society. Buildings with rooftop panels form microgrids acting as prosumers are usually not under control of regulated companies operating public grids. Currently much work has focused on self-consumption individual microgrids. On contrary, CoSSMic system targets at a neighborhood primary goal maximize whole by co-ordinating their storage. To address challenge fluctuating partly...
The growing impact of weather-related power outages on economy and society in the last decades underlines rising need for system resilience. Power resilience can be boosted through adoption probabilistic approaches preventive actions building smart grid capabilities. Decisions best-performing action, however, are nontrivial must consider expected an upcoming event, weather forecasts, fault probabilities, their corresponding uncertainties. This article presents a three-stage decision-making...
CoSSMic (Collaborating Smart Solar powered Micro-grids) is an EU funded project aimed at developing a system for smart management and control of solar energy. The must be relevant to community end-users other stakeholders. Two processes are described here contribute in meeting this aim, user-centered design lean startup product design. We describe iterative approach the which incorporates these two impact it has had on results.
As the main cause of large blackouts, understanding complex interactions involved in cascading failure propagation is a critical area ongoing research. The static model failures well-accepted method to investigate effects power systems. However, as system evolves, dynamic behaviours become more variable, it necessary evaluate validity assumptions model. This paper compares and validates conventional with novel capturing frequency dynamics. N-2 contingency analysis used trigger events...
The increasing number of large-scale power outages caused by extreme weather events or other natural hazards raises the need for higher system resilience. impacts cascading faults, one main mechanisms leading to disruptive affecting hundreds thousands people, can be mitigated intentionally sectionalizing network into stable and self-adequate islands. However, there is only little research on benefit such preventive actions grid This paper presents a model investigating performance exposed...
Preventive actions such as intentional islanding are a promising way of effectively improving power grid resilience and mitigating the propagation cascading faults caused by extreme weather events. However, stochastic nature uncertainty in forecasts make decision on whether to apply preventive action difficult. This paper presents novel strategy that utilizes probabilities provided ensemble forecasting decide prior an event identify most cost-effective action. probability-based is compared...
