Monitoring and Control Facilities table 2. A summary of GridSTAR microgrid loads and DERs. The GridSTAR microgrid includes numerous facilities for real-time Solar Storage monitoring and control. These enable PV (real-time) detection of electrical 5 10.4 conditions requiring alteration of the 0 0 dispatch of available DERs and highspeed transition to islanded mode when warranted by abnormal electri0 250 cal conditions consistent with IEEE 5 0 Standard 1547a. Much of the monitor0 0 ing and control facilities either exist now (e.g., asset controllers for energy 0 0 storage, such as the BEMS at build0 0 ing 101) or will be added in the third 10 260.4 quarter of 2017 as part of the ongoing grid modernization efforts at TNY (e.g., digital relays and substation data concentrators at substation 664). Following is a summary of the monitoring and control facilities that will be included in the GridSTAR microgrid. These monitoring and control facilities are also depicted in Figure 5.

The maximum output of the available DERs (including storage, solar PV, and controllable loads) exceeds average demand by more than 100 kW, making the GridSTAR microgrid a viable candidate for islanded operation under average and off-peak conditions.
