  1. 1. Computing Equivalent hydropower models in Sweden using inflow clustering

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

    Author : Daniel Lilja; [2023]
    Keywords : Hydropower; Equivalent; Bilevel; Optimization; Clustering; Inflow; Sweden; Vattenkraft; Ekvivalent; Bilevel; Optimering; Klusteranalys; Inflöde; Sverige;

    Abstract : To simulate a hydropower system, one can use what is known as a Detailed model. However, due to the complexity of river systems, this is often a computationally heavy task. Equivalent models, which aim to reproduce the result of a Detailed model, are used to significantly reduce the computation time for these simulations. READ MORE

  2. 2. Integration of energy management  and production planning : Application to steelmaking industry

    University essay from KTH/Optimeringslära och systemteori

    Author : Rachid Labrik; [2014]
    Keywords : Scheduling; Linearization methods; Mixed integer linear programming; multi-parametric programming; Bilevel programming; Sensitivity Analysis; ;

    Abstract : Steelmaking industry, one of the most electricity-intensive industrial processes, is seeking for new approaches to improve its competitiveness in terms of energy savings by taking advantage of the volatile electricity prices. This fluctuation in the price is mainly caused by the increasing share of renewable energy sources, the liberalization of energy markets and the growing demand of the energy. READ MORE

  3. 3. Towards the Solution of Large-Scale and Stochastic Traffic Network Design Problems

    University essay from Institutionen för informationsteknologi

    Author : Fredrik Hellman; [2010]
    Keywords : optimization; traffic network design; implicit programming; mathematical programs with equilibrium constraints; cutting plane method; bilevel programming; stochastics; MPEC; SMPEC;

    Abstract : This thesis investigates the second-best toll pricing and capacity expansion problems when stated as mathematical programs with equilibrium constraints (MPEC). Three main questions are rised: First, whether conventional descent methods give sufficiently good solutions, or whether global solution methods are to prefer. READ MORE
