About the Presenter

Marc Mueller-Stoffels

Marc Mueller-Stoffels is the lead researcher for the Wind-Diesel Applications Center and Power System Integration Lab at the Alaska Center for Energy and Power (ACEP). Marc's research focuses on the integration of variable generation sources into isolated micro grids. Most recently he has lead to testing of a inverter-battery system to enable diesel-off mode in high contribution wind scenarios.

Prior to joining ACEP, Marc has developed regional scale climate models with focus on Arctic sea ice, and has chaired a small software company specializing in optimization algorithms. Marc holds graduate degrees in physics from the University of Alaska Fairbanks and Otago University, New Zealand.

The Alaska Center for Energy and Power (ACEP) at the University of Alaska Fairbanks conducts research into hybrid power systems for rural Alaska. Most Alaskan communities are not connected to the road system and can only be reached by air, barge, or ice road. Generally, electricity is generated by diesel gensets in the communities at fairly high costs, with the poorest 20% of the population spending up to 50% of their income on electricity and heating. Wind generators have been integrated into some of the rural powerhouses to mitigate high fuel costs and reduce dependence on long supply lines. Increasing the contribution of wind power in the energy mix can be challenging with respect to power quality and grid stability.

Over the past two years ACEP has developed a Power Systems Integration Laboratory to help better understand the challenges of variable resource (wind/PV) integration into diesel grids. And to test both auxiliary systems (batteries, inverters, etc.) and control strategies to improve grid stability and increase wind penetration levels, including diesel-off operation.

This presentation will give an overview of the research conducted at the Alaska Center for Energy and Power in the context of the challenges due to the remoteness and harsh climate of rural Alaska.
