Development of an Interactive Program to Study of the Continuation Power Flow

Abstract

In this paper an interactive program developed to study of the continuation power flow is presented. Both, the graphical user interface and the power flow program have been developed in the Matlab environment thus providing a good computational performance and a users-friendly teaching software. The interactive program allows the user to edit the input and output data files of the selected power systems as well as to visualize and analyze the results directly on the computer screen. Directly from the system one-line diagram, the graphical interface allows the user change the parameters of the system (bus and lines system data); remove the transmission line clicking directly on it; view the buses voltage and angle profiles and the real and reactive power flows. In order to assess the current operating point condition, the user can also obtain the pre-and post-contingency loading margins by tracing the respective P-V curves. All these characteristics make the developed program recommended for educational purpose.

Mathematical Modeling of Green Tariff Electricity Billing in a Layer Poultry Farm Based on Consumption Indicators

“…Research highlights the importance of energy studies in agribusiness companies. Many studies have examined conventional electricity generation and alternative sources such as that of Canossa et al (2018). Studies of electricity in agribusiness have approached biomass production (Dadario et al, 2023, Dinnebier et al, 2021Ribeiro et al, 2020), farm electrification (Soofi et al, 2022), food and agribusiness enterprises (Khan et al, 2022;Rahman et al, 2022), and energy consumption with agricultural growth (Raeeni et al, 2019).…”

Development of a Pedagogical Graphical Interface for the Reinforcement Learning

“…O MATLAB é um software frequentemente utilizado no desenvolvimento de interfaces gráficas para pesquisas em engenharias e ciências exatas [26], [27], [28]. Alguns exemplos são nas áreas de: telecomunicac ¸ões [26], processamento de imagens [29], sistemas elétricos de potência [27], robótica [30] e otimizac ¸ão [28]. Além disso, o MATLAB também é uma ferramenta bastante utilizada no ensino de disciplinas que envolvam programac ¸ão e métodos numéricos [31], [32].…”
