Figure 4.15 shows when the PV panels in module 1 were disabled for 6 hours the
microgrid and battery banks supply the power to the loads that caused the batteries SOC to
decrease instead of increase and the excess power in the microgrid to fall. Yet, this is to be
expected and what you want to see in a resilient microgrid because the excess power in the
microgrid was able to supply power to the loads during a sudden power supply shut down. A
sudden power supply shut down can be caused by a multitude of reasons but the most common
would be a natural disaster.
4.4 SAM's Breakdown for a House
Using the software System Advisor Model (SAM), a user can gain very useful
information about how renewable generating system can save a user money. SAM software
works by taking the specifics about a renewable generating system and generates charts and
graphs about its theoretical operation. The SAM software has limitations of not being able to
simulate a microgrid. However, using the software shows useful information about how a single
module works in a microgrid it will comprise of solar panels, inverters, batteries, and loads.
To understand what the outputs of the SAM simulation are, let us look at the specifics of
the software. First, when creating a new project in SAM, one needs to know the specifics of the
hardware. Which could include the model number of the solar panels, batteries, and geographical
location of the site. Once all the specifics are known, one can start putting in data to the SAM
software. The software starts with the geographical location of sight. The software makes it easy
because SAM can look at an online database for the specifics of the area. Once the site location
was entered, the software downloads the specifics for a region. SAM then automatically fills in
most of the blank specifics for the solar radiation for a region.47
