Modelling of Non-linear CHP Efficiency Curves in Distributed Energy Systems
Distributed energy resources gain an increased importance in commercial and industrial building design. Combined heat and power (CHP) units are considered as one of the key technologies for cost and emission reduction in buildings. In order to make optimal decisions on investment ...

Modeling of Thermal Storage Systems in MILP Distributed Energy Resource Models
Thermal energy storage (TES) and distributed generation technologies, such as combined heat and power (CHP) or photovoltaics (PV), can be used to reduce energy costs and decrease CO2 emissions from buildings by shifting energy consumption to times with less emissions and/or lower ...

Modeling and Evaluating Beneficial Matches between Excess Renewable Power Generation and Non-Electric Heat Loads in Remote Alaska Microgrids
Develops a decision-making method to identify beneficial matches between excess renewable electricity and non-electric, dispatchable heat loads in remote Alaska microgrids. Uses HOMER Pro to model excess generation across multiple wind and solar build-out combinations and then qua...

Load Control for Frequency Response A Literature Review
As electricity grids employ greater fractions of renewable energy, which introduce additional variability and uncertainty in the net-load, balancing electrical load and generation becomes more challenging. This paper reviews the literature documenting physical simulations and real...

Security-Constrained Design of Isolated Multi-Energy Microgrids
Energy supply in rural and off-grid communities has traditionally relied on diesel-based microgrids, due to limited access. But global environmental concerns are pushing for the transformation of these systems into renewable-based microgrids. This transition to more complex system...
