In conventional power generation systems, large centralized plants operating on fossil fuel mainly generate the electric power. The generated electricity has to travel through the long transmission and distribution lines to be delivered to the end users. In addition to being costly, this structure yields poor reliability and low efficiency. On the other hand, serious concerns have been raised about the shortage of fossil fuels, global warming, and energy security. As a result, the power systems are moving toward more distributed structures based on renewable energy resources.
During the last decade, the concept of small-scale energy resources distributed over the grid has gained a considerable interest. This concept is often called distributed generation (DG). DG systems are mainly using renewable energy sources as their prime movers. Renewable energy sources (including biomass, wind, solar, hydropower, and geothermal) can provide clean, efficient, reliable and adequate energy supply while making modern energy services accessible and affordable.
However, despite the substantial benefits of distributed generation, the application of an individual DG system can cause as many problems as it may solve. To avoid such problems and to realize the emerging potential of distributed generation, a system approach has been taken, in which generation and loads are considered as a subsystem called “micro-grid”.
One important issue in the existing power network is the capability of renewable energy sources to increase the power quality of the micro-grid. One aspect of this feature is harmonic compensation using distributed resources.
In this thesis an adoptive notch filter (ANF) is employed in the control system of a distributed generation (DG) system for harmonic compensation. It is shown that the performance of the system is highly improved using the adoptive notch filter. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2014-02-01 08:16:28.205
