  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

  3. 2. 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 :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. 3. 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).

  5. 4. Optimisation and Incentive Mechanisms for Robust Generation Dispatch and Capacity Investment in Electricity Markets

    Författare :Lamia Varawala; György Dán; Mohammad Reza Hesamzadeh; José Manuel Arroyo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal power flow; Look-ahead; $N-k$ contingency criterion; Renewable energy; Environmental externalities; Electricity generation capacity; Strategic behaviour; Incentives;

    Sammanfattning : Power systems constitute a large-scale critical infrastructure and therefore, it is crucial that their operation be robust to deviations from normal functioning of its independent components. Furthermore, due to their large size, any inefficiencies in electricity market design can be very costly and therefore, must be optimised. LÄS MER

  7. 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 :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
