  Activated sludge models are widely used to simulate, optimize and control performance of wastewater treatment plants (WWTP). For simulation of nutrient removal and energy consumption, kinetic parameters would need to be estimated, which requires an extensive measurement campaign. In this study, a novel methodology is proposed for modeling the performance and energy consumption of a biological nutrient removal activated sludge system...

  - Annals of Computer Science and Information Systems - Rok 2016

  The paper presents modeling and simulation of energy consumption of two types of parallel applications: geometric Single Program Multiple Data (SPMD) and divide-and-conquer (DAC). Simulation is performed in a new MERPSYS environment. Model of an application uses the Java language with extension representing message exchange between processes working in parallel. Simulation is performed by running threads representing distinct process...

• Energy Consumption Modeling in SPMD and DAC Applications

  Publikacja

  • J. Kuchta

  - Rok 2016

  In this chapter, we show a study of energy consumption during execution of SPMD and DAC application – the same applications which time of execution we modeled in the previous two chapters. We measured an average power usage at a single node of the GALERA+ cluster during application execution and then we modeled the total energy consumption by the application. Next we simulated the applications using MERPSYS and we compared the...

• Decentralized Microgrid Energy Management System with Market-Based Energy Trade System

  Publikacja

  • A. Włodarczyk
  • A. Kowalczyk
  • J. Tarnawski

  - Rok 2018

  This paper presents a decentralized energy management system for a power microgrid, which integrates individual users, who own renewable energy sources and energy storages. The purpose of the system is to make optimal use of available resources to cover the electricity needs of the whole microgrid. Thanks to the energy exchange system, in addition to exchanges with the distribution network, the system also allows trades within...

• Energy Modeling of Single-Family Houses in the Conceptual Phase

  Publikacja

  • M. Helenowska-Peschke

  - Rok 2018

  The aim of the article is to identify the potential impact of the latest commercial digital tools for building energy analysis on the everyday architectural practice in Poland in the context of typology and energy optimization of single –family houses. The reason for this survey is that “architect friendly” interfaces simulation results’ visualization and energy analysis tools are not given deserved attention in the architectural...

• Energy Management of Microgrid System

  Publikacja

  • M. Włas

  - Rok 2011

  W artykule przedstawiono system sterowania rozproszonych źródeł energii (DER) w oparciu o protokół Ethernet POWERLINK. Autorzy opracowali metody komunikowania się z systemu Zarządzania Energią z przekształtnikami energoelektronicznymi w system zwany mikrosiecią (Microgrid). W artykule przedstawiono optymalny podział mocy pomiędzy źródłami wytwórczymi a obciążeniem. System ten składa się z: kogeneratora z silnikiem na gaz ziemny...
