The role of distributed generation in the critical electric power infrastructure

The major distributed power generation (DG) technologies which are discussed are: microturbines, fuel cells and photovoltaic power systems. Other DG technologies to be discussed are: combustion/diesel engines, and wind. However, these are not be discussed in detail due to insufficient wind speed availability in all geographic regions; and combustion/diesel engines because of high emissions, and operation and maintenance costs. In addition, most internal combustion engines are designed for stand-by service and not continuous duty. The study shows that DG technologies have a much greater market potential in areas with high electricity costs and low reliability such as in developing countries
