  1. 1. On the Efficiency and Accuracy of Simulation Methods for Optimal Power System Operation : Convex Optimization Models for Power System Analysis, Optimal Utilization of VSC-type DC Wind Farm Grids and FACTS Devices

    Författare :Mohamadreza Baradar; Mohammad Reza Hesamzadeh; Damien Ernst; KTH; []
    Nyckelord :Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Recently, significant changes in electric power systems such as rapid developmentof smart grid and electricity market and integration of non-dispatchablesources have added more complexity to the Power Flow Scheduling (PFS) andPower Balancing (PB) models. For instance, non-dispatchable sources introducean increasing level of uncertainty in the electricity market and power system operation. LÄS MER

  2. 2. Data driven modeling in the presence of time series structure: : Improved bounds and effective algorithms

    Författare :Othmane Mazhar; Boualem Djehiche; Cristian R. Rojas; Carlo Fischione; Mohammad Reza Hesamzadeh; Boualem Djehiche; Munther Dahleh; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Time series; Non-asymptotic estimation; Minimax; Change point detection; Hidden Markov model; State space model; Least square; Penalized Regression; Random covariance matrix; Concentration inequality; Chaining integral; Self-normalized martingale inequality; Cramér-Rao inequality; van Trees inequality; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : This thesis consists of five appended papers devoted to modeling tasks where the desired models are learned from data sets with an underlying time series structure. We develop a statistical methodology for providing efficient estimators and analyzing their non-asymptotic behavior. LÄS MER

  3. 3. Impact of High levels of Wind Penetration on the Exercise of Market Power in the Multi-Area Systems

    Författare :Ekaterina Moiseeva; Mohammad Reza Hesamzadeh; Frank Anthony Wolak; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind integration; market power; game theory; mathematical programming; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : New European energy policies have set a goal of a high share of renewable energy in electricity markets. In the presence of high levels of renewable generation, and especially wind, there is more uncertainty in the supply. It is natural, that volatility in energy production induces the volatility in energy prices. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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).

  5. 5. Optimal bidding of a hydropower producer insequential power markets with riskassessment : Stochastic programming approach

    Författare :Yelena Vardanyan; Mohammad Reza Hesamzadeh; Javier Contreras; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Short-term hydropower planning and bidding under uncertainty is a complicated task. The problem became more challenging with the liberalized market environment within the last two decades. LÄS MER
