Energy management of islanded power systems & microgrids

Speaker: Elias Afeiche, ABB Power Generation – Grid Automation

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

Renewable integration into islands: Fuel independence and lower LCOE


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
