1. 21. Techno-economic Analysis of Combined Hybrid Concentrating Solar and Photovoltaic Power Plants: a case study for optimizing solar energy integration into the South African electricity grid

   University essay from KTH/Kraft- och värmeteknologi

   Author : Luis Ramon Castillo Ochoa; [2014]
   Keywords : Photovoltaic; Concentrated Solar Power; PV; CSP; control strategy; combined; hybrid; storage;

   Abstract : The cooperation between large scale Concentrated Solar Power plants (CSP) and Solar Photovoltaic (PV) parks can offer stability in power supply and enhance the capacity factor of the CSP plant intended to cover a common demand on the power system. Moreover, it can offer an investment option with lower risk. READ MORE

3. 22. Improving Low Voltage Ride-Through Requirements (LVRT) Based on Hybrid PMU, Conventional Measurements in Wind Power Systems

   University essay from Avdelningen för fysik och elektroteknik

   Author : Chinedum Ekechukwu; [2014]
   Keywords : State Estimation; Power Systems; Unscented Kalman Filters; Phasor Measurement Units;

   Abstract : Previously, conventional state estimation techniques have been used for state estimation in power systems. These conventional methods are based on steady state models. As a result of this, power system dynamics during disturbances or transient conditions are not adequately captured. READ MORE

4. 23. The Price of Synchrony:Evaluating Transient Power Losses inRenewable Energy IntegratedPower Networks

   University essay from KTH/Reglerteknik

   Author : Emma Sjödin; [2013]
   Keywords : ;

   Abstract : This thesis investigates the resistive losses incurred in returning a power network to a synchronous state following a transient stability event, or in maintaining this state in the presence of persistent stochastic disturbances. We quantify these transient power losses, the so-called “Price of Synchrony”, using the squared H2 norm of a linear system of generator and load dynamics subject to distributed disturbances.

5. 24. MODELLING OF LARGEPOWER SYSTEMS AND TUNING OFREGULATORS’ PARAMETERS

   University essay from KTH/Elektriska energisystem

   Author : David Petesch; [2013]
   Keywords : ;

   Abstract : Interconnection between France and Italy under the Alps could impact the European power system stability. Indeed, the HVDC lines are active elements of electrical grid that influence its dynamic behaviour in case of disturbances. READ MORE

6. 25. Dynamic voltage regulation using SVCs : A simulation study on the Swedish national grid

   University essay from KTH/Elektriska energisystem

   Author : Oscar Skoglund; [2013]
   Keywords : Voltage stability; FACTS; SVC;

   Abstract : Voltage stability is a major concern when planning and operating electrical power systems.As demand for electric power increases, power systems are stressed more and more. TheFACTS family of components were introduced to utilize the existing grid to a higherdegree, while still maintaining system stability. READ MORE
