Description
Summary:Dispersed generation is considered as a novel approach in the field of electricity production. In fact, there are no standard definitions, or a standard term has been approved for this type of power generation right now. However, various terms and definitions about distributed generation have been employed in the previous kinds of research. For instance, North American countries use the term ‘dispersed generation,’ Anglo-American centuries the term ‘embedded generation,’ and some parts of Asia as well as Europe countries, the term ‘decentralized generation’ is used for this kind of production. In general, distributed generation can be defined as small-scale electric power generation that is connected to the distribution system. DG term refers to using modular technology which is located throughout utility’s service region. Distributed generation units are energized by solar, the wind, and fuel cell. There are a set of dispersed generation technologies in the market such as the wind and solar that started dominating on the local electricity markets due to their availability of such resources and free emission characteristics. It is worth mentioning that integrating dispersed generation into current networks has altered power flow pattern from traditional vertical to bi-directional power flow which contributed to enhancing voltage stability and minimizing power losses of the whole system. However, arbitrary integration of DG units in the system may cause some technical issues. In this paper, Newton–Raphson method and modal analysis are employed to identify the proper allocation of DG in the system. The 14 IEEE system has been selected to implement this approach by using a MATLAB software.
