  1. 1. Application of Mathematical Programming to Short-Term Operation Planning of Hydrothermal Power System

    Författare :Hooshang Habibollahzadeh; Janis Bubenko; Denis Sjelvgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Short-Term Operation Planning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The thesis contains the results of a reseach project on application of mathematical programming methods to short-term operation planning of large hydrothermal power systems. The project was aimed at devoeloping efficient solution techniques that are practially applicable to large systems. The problem is modeled as a large mixed integer program.. LÄS MER

  3. 2. On stochastic optimization for short-term hydropower planning

    Författare :Yelena Vardanyan; Lennart Söder; Mikael Amelin; Afzal Siddiqui; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Renewable generation is the fastest growing energy resources in the past decade. Renewable energy sources, particularly wind power, provide clean and environmentally friendly energy to meet the system demand, meanwhile introducing huge levels of uncertainty in the system.

  4. 3. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints

    Författare :Nilsson Olof; Lennart Söder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Integer Constraints; Lagrange relaxation; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... LÄS MER

  5. 4. Planning and Operation of Demand-Side Flexibility

    Författare :Meng Song; Mikael Amelin; Alessandra Parisio; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Power systems are changing with growing penetration of non-dispatchable renewable generation and increased demand of electric energy. More generation, transmission or distribution capacities are needed to balance the varying production and higher consumption. Demand-side flexibility is a potential solutionto tackle those challenges. LÄS MER

  7. 5. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

    Författare :Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.
