... The integration of battery energy storage systems with photovoltaic systems to form renewable microgrids has become more practical and reliable, but designing these systems involves complexity and relies on connection standards and operational requirements for reliable and safe grid-connected operations.
You also evaluate the microgrid and controller operations against various standards, including IEEE® Std 2030.9-2019, IEC TS 62898-1:2017 and IEEE Std 2030.7-2017. The planning objectives in the design of the remote microgrid include power reliability, renewable power usage, and reduction in diesel consumption.
There are a variety of current sensing technologies that can monitor the status of an HEV or EV battery. The solution varies with the voltage and capacity of the battery. As shown in Figure 1, there are two main locations where you can measure current: top of stack (high-side sensing) and bottom of stack (low-side sensing). Figure 1.
The microgrid comprises: The Diesel Substation, BESS, & Microgrid Controller subsystem includes the model of the diesel generator and the BESS. This subsystem also connects the diesel generator to the microgrid at the point of common coupling (PCC). Two outgoing MV feeders from the substation connect the microgrid assets.
This subsystem also connects the diesel generator to the microgrid at the point of common coupling (PCC). Two outgoing MV feeders from the substation connect the microgrid assets. The MV load and the PV subsystem connect to the Feeder 1 while the LV load connect to the Feeder 2 through the secondary substation.
