Case studies of microgrids systems

Microgrids (MGs) are becoming more attractive due to their ability to reduce energy costs for customers, allow the full exploitation of renewable energy sources and increase security, reliability and resiliency of the power distribution system. Moreover, the integration of MGs into power systems will alleviate the consequences of sudden grid outages on the end users and provide higher power security to critical loads. In addition, thanks to their ability to produce energy close to the consumption points, MGs offer a possible solution for reliable energy supply into the areas where the extension of power grids is considered technically and economically unfeasible. Nonetheless, their practical implementation into actual distribution networks is still hindered by several technical and economic issues. This chapter aims to show, by using several Case Studies of MGs, the value of each MG system in providing energy efficiency, ancillary services, demand response and electricity bill reduction.
