Research ArticleOpen accessPhrase in the titleElectric Power System Under-Voltage Load Shedding Protection Can Become a TrapLuiz Augusto Pereira Fernandes, Alexandre Rocco, Heraldo Silveira Barbuy, Geraldo Caixeta GuimarãesProblem statement: Under-Voltage Load Shedding (UVLS) protection of Electric Power Systems (EPS) is frequently used against Voltage Collapse (VC), however when there is automatic bus voltage regulation with excessive capacitive compensation, the UVLS scheme may not trip. In this case, load shedding must be based in a Voltage Collapse Proximity Indicator (VCPI). Many UVLS procedures may not be appropriate today. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,203 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleDesign of New Load Shedding Special Protection Schemes for a Double Area Power SystemH. Seyedi, M. Sanaye-PasandIn this paper several Under Frequency Load Shedding (UFLS) schemes are designed as special protection schemes to preserve the integrity of islands, formed following the outage of tie lines connecting two areas in a double area power system. For the purpose of analysis, the Iranian interconnected grid is simulated in a suitable power system analysis software. The grid is connected … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,572 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEfficiency Assessment of Software-Defined Networking for Real-Time Network SystemsNeelam Gupta, Sarvesh Tanwar, Sumit BadotraSoftware Networking (SDN) is growing in popularity due to its benefits, which include portability, mobility, analytics, and ease of creation. But it needs to be adequately shielded from security risks. One of the main vulnerabilities to the SDN network is the Distributed Denial-of-Service (DDoS) attack. To fulfill the demands of the complex and demanding security concerns of today, a new … …Journal of Computer Science, Vol. 20, Issue 6 · 8 Apr 2024 · 4,918 accessesView PDF Cite

Research ArticleOpen accessIn the abstractElectrical Load Forecasting Using Artificial Neural Network: The Case Study of the Grid Inter-Connected Network of Benin Electricity Community (CEB)Adekunlé Akim Salami, Ayité Sénah Akoda Ajavon, Koffi A. Dotche, Koffi-Sa BedjaThe low rate of electrification seems challenging in many West African countries and many strategies are underway to improve upon. In this regard, the target of achieving the universal access and services calls for a stable and reliable electrical network. Forecasting of electrical load on a connected grid network is very delicate and requires tremendous task from the utilities (billing … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 Apr 2018 · 9,143 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCOMPARATIVE STUDY OF DIFFERENT KALMAN FILTER IMPLEMENTATIONS IN POWER SYSTEM STABILITYH. H. Goh, C. W. Tai, Q. S. Chua et al.Voltage stability and voltage collapse issues have in recent years begun to constitute an unpleasant warning to the operational security of power systems. Many techniques have been investigated in order to predict the point of voltage collapse. However, there are still several restrictions due to the insufficiency of current system state information. Accompanied by the commencement of the Phasor Measurement … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,190 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Capability of Young Layers for Survival after Salmonella entritidis ChallengeE. S. Soliman, H. Busby, C. Kilpatrick et al.Problem statement: Genetic line differences in resistance of layer hens and young chicks to Salmonella entritidis have been identified through a lot of studies. That is why the agricultural industry was prepared for the potential phasing out of antibiotics for use in controlling bacterial pathogens. Early infection may result in long term colonization of layers with Salmonella entritidis, resulting in … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,780 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVoltage Collapse Risk Associated to Under-Voltage Capacitive Compensation in Electric Power System OperationHeraldo Silveira Barbuy, Alexandre Rocco, Luiz Augusto Pereira Fernandes, Geraldo Caixeta GuimarãesProblem statement: In the operation of an Electric Power System (EPS), it has been usual to provide reactive power injection to avoid an under-voltage bus condition. In some situations an adequate voltage profile will not be a guarantee against Voltage Collapses (VCs) that may cause blackouts as seen in many occurrences around the world. The repeatedly injection of reactive power … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,253 accessesView PDF Cite
