Can microgrid cost information be collected?
Despite the relative novelty of the microgrid market and the challenges faced when discussing microgrid costs, it is a very useful exercise to collect cost information from the microgrid community and better understand component costs and differences from one project to another. The principal goal in Phase I of the study was to collect data.
What is a microgrid cost model?
The U.S. Department of Energy commissioned the National Renewable Energy Laboratory to complete a microgrid cost study and develop a microgrid cost model. The goal is to elucidate the variables that have the highest impact on costs as well as potential areas for cost reduction. This study consists of two phases.
Why are microgrid costs not accounted for?
It could be possible that when there is load management or other refined enterprise-level controls in Level 3 or higher, the required software and hardware are not accounted for in the collected costs or were already there and integrated into the microgrid. Figure 17. Box plot of normalized microgrid costs by microgrid levels Table 2.
How reliable is a building microgrid?
The building microgrid without DG demonstrates a robust reliability, with approximately 10% more probability of surviving outages than the microgrid with DG. For outages lasting more than 4 h, the probability of surviving outages increases at additional costs.
