Prevention efforts, insurance demand and price incentives under coherent risk measures
(Elsevier, 2020)
This paper studies an equilibrium model between an insurance buyer and an insurance seller, where both parties' risk preferences are given by convex risk measures. The interaction is modeled through a Stackelberg type game, ...
Assessment of Distributed Generation Hosting Capacity of Microgrids with Thermal Smart Loads
(Ieee, 2020-01-01)
This paper seeks to explore the problem of assessing the renewable distributed generation (DG) hosting capacity of microgrids when thermal smart loads composed of electric water heaters (EWH) interfaced with electric springs ...
Projeto de uma bancada de testes para avaliação do carregamento detransformadores trifásicos de potência utilizando conversores estáticos
(Universidade Federal de Minas GeraisUFMG, 2007-03-29)
This work presents the design of a setup for load tests in power transformers, mainly in adverse conditions. Such operation conditions can reduce life expectancy of the power transformers, mainly if it operates overload ...
Optimisation-based switch allocation to improve energy losses and service restoration in radial electrical distribution systems
(2016-08-04)
This study presents a newmethodology for the optimal allocation of switching devices in radial electrical distribution systems (EDSs). A specialised greedy randomised adaptive search procedure (GRASP) algorithm defines the ...
Optimization of Spinning Reserve in Stand-alone Wind-Diesel Power Systems
(IntechOpen, 2010)
Spinning reserve carried on synchronized units is the most effective resource available to the system operators for managing unforeseen power unbalances, such as demand fluctuations and the sudden loss of generation ...
Effect of dietary energy and stocking density on the performance and sensible heat loss of broilers reared under tropical winter conditions
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2013-03-01)
The objective of the present study was to evaluate the effects of different dietary energy levels and stocking densities on the thermoregulating parameters, live performance, and carcass traits of broilers reared under ...
Bus-based reliability indices and associated costs in the bulk power system
(1998)
This paper presents a methodology to evaluate the reliability and to calculate interruption costs at the load bus level in the bulk power system (Hierarchical Level II). The method is based on a nonsequential Monte Carlo ...
Análise de dados de vida de atuadores eletro-hidráulicos das turbinas de uma central termoelétrica
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Especialização em Engenharia da ConfiabilidadeUTFPR, 2017-11-10)
This work was conceived from the observation of an existing problem of variability in the useful life of the turbine’s electro-hydraulic positioner actuator of the ArcelorMittal Tubarão Power Plant. Thereby, from the ...
