Conventionally electricity is generated in large central units that are connected to the high-voltage transmission system. The distribution networks are being used for delivering the electricity to the customers. Most electric distribution systems are designed, protected, and operated on the premise that there is a single source of electric power on each distribution feeder at any given time. Because interconnecting Distributed Resources (DR) (known as Distributed Generation DG) violates this basic assumption, there are special requirements for connecting to utility distribution systems. These technical requirements can be complex, blending traditional distribution engineering practices with added attention to power quality concerns, safety, and installation needs for advanced DR technologies. There are also many economical issues to be addressed due to the interconnection of different types of DG’s. Distributed generation (DG) has the potential to play an important role in a future sustainable energy system. Properly applied distributed generation, installed on a significant scale, can have very positive effects on the environment, energy efficiency, security of supply and price of electricity paid by consumers. However there are still barriers, technical and non-technical, that are limiting the introduction and use of DG.Objectives
The main objective of this course is to provide up-to-date knowledge about the technical and economical issues relating to the distribution generation. In addition to an introduction to various generating technologies, a more detailed part will be included discussing various applications of power electronics. The impacts of DG to the distribution system will be presented. The focus will be on electrical issues such as grid connection, losses, planning, protection, and control. In addition, the economical and regulatory issues will be addressed. Effects of DG on voltage regulation, relaying, losses, islanding and standards will be examined.
