  1. 1. Strategies, Methods and Tools for Solving Long-term Transmission Expansion Planning in Large-scale Power Systems

    Författare :Desta Zahlay Fitiwi; Lennart Söder; Michel Rivier; Fernando de Cuadra; Andres Ramos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission expansion planning; uncertainty and variability; optimization; stochastic programming; moments technique; clustering; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Driven by a number of factors, the electric power industry is expected to undergo a paradigm shift with a considerably increased level of variable energy sources. A significant integration of such sources requires heavy transmission investments over geographically wide and large-scale networks. LÄS MER

  2. 2. Unit Commitment : Computational Performance, System Representation and Wind Uncertainty Management

    Författare :Germán Morales-España; Lennart Söder; Andres Ramos; Paulien M. Herder; Michel Rivier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik; Mathematics; Matematik;

    Sammanfattning : In recent years, high penetration of variable generating sources, such as wind power, has challenged independent system operators (ISO) in keeping a cheap and reliable power system operation. Any deviation between expected and real wind production must be absorbed by the power system resources (reserves), which must be available and ready to be deployed in real time. LÄS MER

  3. 3. Efficient reduction techniques for a large-scale Transmission Expansion Planning problem

    Författare :Quentin Ploussard; Luis Olmos; Andres Ramos; Efraim Centeno; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy; electricity; transmission expansion planning; linear programming; integer linear programming; relaxation methods; clustering; dimension reduction; network theory graphs ; partitioning algorithms; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of Transmission Expansion Planning (TEP) studies is to decide which, where, and when new grid elements should be built in order to minimize the total system cost. The lumpiness of the investment decisions, together with the large size of the problem, make the problem very hard to solve. LÄS MER

  4. 4. Optimal Long-Term Generation-Transmission Planning in the Context of Multiple TSOs

    Författare :Yaser Tohidi; Mohammad Reza Hesamzadeh; Andres Ramos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission-generation expansion planning; game theory; mathematical programming; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Power system transmission is undergoing rapid changes by the advent of renewable resources of energy, distributed generation, market integration, etc. Transmission planning is, nowadays, about building more inter-connections between adjacent regions or connecting off-shore wind farms to the grid or augmenting the network to support new path flows of energy and is still almost entirely the responsibility of regulated transmission system operator (TSO).
