Key Differences
0.01 – 1
Disaster reliefs, army bases, remote islanded facilities – mainly
for diesel generators (DGs) using distributed communication
architecture
0.1 – 10
Solution for small- to mid-sized microgrids using DG, solar
photovoltaic (PV), battery energy storage system (BESS) for
simple bus topology using distributed communication architecture
1 – 1,000
Solution for mid- to large-sized microgrids using any kind of
distributed energy resource (DER) (natural gas turbine / diesel /
steam / solar PV / BESS / wind / fuel cell) using centralized
communication architecture
10 – 5,000
Solution for mid- to large-sized industrial facilities using any kind
of DER (NG / DG / steam / solar PV / BESS / wind / fuel cell)
using centralized communication architecture
Solution for wide-area protection to maintain grid-wise stability
using distributed and centralized architecture; remedial action
