An economic evaluation for an autonomous independent network of distributed generators

This paper proposes a method for economic evaluation of an autonomous independent network of distributed generators. There are some proposals for this kind of networks and microgrid is one of them. Microgrid is a new framework of power delivering system, which is formed by small, modular generation systems connected to each other to realize an autonomous small grid. In this paper, the total cost when the consumers in a microgrid optimally operated their distributed generators (DG) and energy storage systems (ESS) is reasonably estimated. It includes not only installation and operation costs but also the additional expenses to construct the microgrid. The authors try to find out whether it is economical or not for consumers to form this kind of autonomous independent network
