4. 18. Design of a small scale hybrid photovoltaic and wind energy system

   Kandidat-uppsats,

   Författare :Matilda Kjellander; Anders Tengvall; [2014]
   Nyckelord :Hybrid-system; wind; solar; AC-coupling; DC-coupling; power system;

   Sammanfattning : Approaching problems with global warming due to the use of fossil fuels, means that new system solutions have to be investigated. This report investigates the possibility to expand an existing photovoltaic system with a wind turbine generator to simplify the expansion of renewable energy sources. LÄS MER

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

   Master-uppsats, Avdelningen för fysik och elektroteknik

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

   Sammanfattning : 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. LÄS MER

7. 20. Feasibility of Introducing Hybrid Buses in Bus Rapid Transit Systems in Latin America: The Case of Transmilenio Bogota

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Miguel Sebastian Lema Dimate; [2012]
   Nyckelord :low carbon transportation technologies; bus rapid transit; Hybrid electric buses; sustainable transportation.; Earth and Environmental Sciences;

   Sammanfattning : Bus rapid transit (BRT) systems have been recognized around the world by combining the advantages of urban rail transit systems with the flexibility and low cost of conventional bus systems. Although its introduction in different cities has helped to reduce greenhouse gas emissions and improve air quality, one of the major criticisms for these systems is that buses are usually powered by diesel, which is a pollutant and non-renewable energy source.
