Microgrids
October 11, 2018 Slide 2
Generation at the point of consumption and always available
Distributed energy resources and loads that can be operated in a controlled, coordinated way either connected to the main power grid or in “islanded”* mode.
Microgrids are low or medium voltage grids without power transmission capabilities and are typically not geographically spread out.

Secure power generation and fuel cost savings
Fossil fuel cost is volatile
Steady decline of renewable energy cost, making it economically viable
An optimized energy mix leads to a lower cost of electricity

Managing power fluctuations from renewables
Renewable integration challenge: No compromise on reliability
ROI: Return of Investment
Solar power variations Wind power variations
Inherent volatility of renewables can compromise grid stabilityGrid stability requirements are traditionally fulfilled by diesel generation (base load)Optimized microgrid solution maximizes ROI* and fuel savings
