  1. 1. Techno-Economic Analysis of Organic Rankine Cycles for a Boiler Station : Energy system modeling and simulation optimization

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jamel Hudson; [2019]
    Keywords : Organic Rankine cycle; ORC; Working fluids; Boiler station; District heating system; Simulation model;

    Abstract : The Organic Rankine Cycle (ORC) may be the superior cycle for power generation using low temperature and low power heat sources due to the utilization of high molecular mass fluids with low boiling points. They are flexible, simple, easy to operate and maintain, and offer many possible areas of applications including waste heat recovery and power generation from biomass, geothermal and even solar energy.

  2. 2. Improved Transformer Duality Model for Geomagnetically Induced Currents

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Martin Karlsson; [2018]
    Keywords : ;

    Abstract : A lumped element transformer tank model has been developed for evaluating the power dis-sipation in the tank and flux distribution in the transformer when it is subjected to a DC current in the neutral. FEM simulations are performed to assist in developing a per-phase magnetically separated transformer tank model that takes into account currents induced in the tank. READ MORE

  3. 3. Modeling and Simulation of a Hybrid Powertrain

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Abstract : Hybrid powertrains represent the current trend on passenger cars. The purpose of thisreport is to create a basic model of a hybrid powertrain in Matlab/Simulinkenvironment and study their performance over certification driving cycle. Threecommonly used architectures are modeled and discussed in Simulink. READ MORE

  4. 4. Lifetime estimation of lithium-ion batteries for stationary energy storage system

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Joakim Andersson; [2017]
    Keywords : Li-ion battery; State of charge; State of health; Kalman filtering; Energy Storage;

    Abstract : With the continuing transition to renewable inherently intermittent energy sources like solar- and wind power, electrical energy storage will become progressively more important to manage energy production and demand. A key technology in this area is Li-ion batteries. READ MORE

  5. 5. Development of battery models for on-board health estimation in hybrid vehicles

    University essay from KTH/Materialvetenskap

    Author : Javier Riesco Refoyo; [2017]
    Keywords : Lithium-ion battery; State-of-health; Resistance; Capacity; Materials; Model; Equivalent circuit model; Support vector machine; Neural networks;

    Abstract : Following the positive reception of electric and hybrid transport solutions in the market, manufacturers keep developing their vehicles further, while facing previously undertaken challenges. Knowing the way lithium-ion batteries behave is still one of the key factors for hybrid electric vehicles (HEVs) development, especially for the requirements of the battery management system during their operation.
