This study deals with the problem of voltage security in microgrids. In general, is an issue for power systems, where lack reactive a concern. For microgrids complexity imposed, since frequency and level deviations may take place by operation droop‐controlled inverters. incorporates load margin calculation into microgrid structure. this purpose, special flow program developed order to consider effects Simulation results are obtained help islanded distribution system only generators coupled...
Island Microgrids can coordinate local energy resources, provide post-fault reliability improvements for customers, and aggregate power resources to offer services the wider system. A crucial component of an Microgrid is battery storage system, which manage imbalances, alleviate constraints, improve by enabling islanding. planning sizing method required quantify maximize benefits while avoiding over-investment under-utilization. This paper combines comprehensive assessment with...
Power system blackouts harm economic activities and worsen the customers' welfare. Smart grids' self-healing capacity is an important feature for future power systems it should also include ability to manage distributed energy sources ensure electricity supply a long time. This required because blackout duration unknown buck blackstart complex task. paper proposes methodology microgrid management control maximize of in emergency situations. In order accomplish this goal, some options are...
Objective:This study describes and analyzes a telehealth strategy for Family Health Teams (FHTs) providing primary care services. This aimed to increase the adherence treatment of hypertension. Subjects Methods: We conducted before–after that enrolled 21 professionals 502 hypertensive patients in two Units connected our Telehealth Center Network. Seminars addressing hypertension were offered by Web conferences, period 6 months, FHTs. The antihypertensive drugs, low salt diet, physical...
This paper proposes some methods for the purpose of reactive power and voltage control. Real cases show them as potentially harmful systems, since dynamic instability collapse may appear. Control actions like tap changers, active redispatch help system stability, but present reverse results operating conditions. is firstly devoted to identify classify an point under stability view. Following this classification, index assess robustness a bus proposed. The studies are carried out with QV...
<i>Background/Aims:</i> Metabolic syndrome (MS) and fatty liver disease (FLD) are on the rise. The association between these conditions in Brazilian youth is analyzed. <i>Methods:</i> 354 subjects (11.2 ± 3.1 years) were evaluated. FLD was suspected by ultrasound computed tomography; weight MS BMI z-score NCEP-ATPIII respectively. <i>Results:</i> Subjects classified as: group 1 with 2 without as ‘a’ (overweight/obese) ‘b’ (normal weight). Comparing 2a 2b,...
Abstract Multi‐energy microgrids could result in more flexibility and increase reliability by interconnecting networks. Electricity gas networks exhibit very different dynamic behaviours response to a fault or failure. Gas have built‐in energy storages that can continue provide reliable supply if inputs the system are compromised. This study presents novel assessment method applied multi‐energy microgrids; combines an incidence matrix analysis identifies connectivity between sources load...
In this paper a new Software-in-the-Loop (SIL) strategy is proposed for real-time testing of Coordinated Volt/VAr Control (CVVC), through the use Real-Time Digital Simulator (RTDS) and Matlab® program. Such seeks to emulate, during test, interaction commonly established among main layers Distribution Management System (DMS). To do so, TCP/IP (Transmission Protocol/Internet Protocol)-based communication between simulation module RTDS (RSCAD) established. prove efficiency SIL strategy, an...
The voltage regulation problem is very complex and important in electric power systems. Such related to keep the voltages within pre-determined levels according current legislation. application of smart grids' concepts helps this by giving more background take decisions enabling possibility considering a wider picture system control actions. This paper proposes multobjective distribution systems using Artificial Immune Systems. proposed methodology considers active losses, nonconformity...
RESUMO Este estudo oferece uma análise da produção minerária, ressaltando sua importância histórica para os territórios onde se desenvolveu, com presença em diversas regiões do Brasil, diferentes escalas. No que diz respeito à região mineradora de Minas Gerais, especialmente no município Brumadinho, a introdução atividade extrativismo mineral insere-se um contexto progresso, associado grande indústria e centralidade econômica. A partir dos anos 30, mineração porte estabeleceu na região,...
Energy storage systems (ESSs) can benefit distribution networks by providing multiple services to the system operator and contributing reliability. Given high capital costs of ESS, it is beneficial optimally design them for their intended applications; however, this be computationally expensive due non-convex formulation AC power flow, complexity business use cases simulation multi-period operations. This study develops a comprehensive model size ESS minimise lifetime maximise The flow...
