6. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation
Abstract : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. READ MORE

7. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies
Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE

8. Wind Power - Added Value for Network Operation
Abstract : This dissertation deals with the investigation on different value added properties of variable speed wind turbines (VSWT) that stem from the flexible controllability of converter interfaced wind turbines (WT). Improvements in voltage and transient stability of a nearby grid, small-signal stability improvement on the power system, frequency control support for the network operation, as well as thetechnical and the economic issues related to the reactive power ancillary service provision, are among the issues covered.

9. Aspects of Blame : In which the nature of blame, blameworthiness, standing to blame and proportional blame are discussed
Abstract : This thesis discusses what blame is, what it is for an agent to be blameworthy for having performed a certain act or omission, what makes an agent blameworthy for having performed a certain act or omission, whether the idea of standing to blame generalises to blame understood as something privately held, and what it is for blame to be proportionate. It provides original answers to these questions that move the current discussion of blame forward. READ MORE

10. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE
