Module 1
Three-Phase Power at the Grid Connection
1
Power Triangle Analysis in Balanced Three-Phase Systems
Interpret active power, reactive power, apparent power, and power factor using a power triangle for a balanced three-phase system.
2
Three-Phase Power Calculation from Voltage, Current, and Power Factor
Calculate three-phase MW and MVAr from line-to-line voltage, line current, and a specified power factor.
3
Tracing BESS Power Flow from Batteries to the Grid POI
Trace the power path from batteries through the power conversion system (PCS), transformers, and point of interconnection (POI) on a BESS single-line diagram.
4
Translating Meter and Inverter Power Sign Conventions
Translate charging, discharging, and reactive-power exchange between explicitly defined meter and inverter sign conventions.
5
Calculating Net POI Power from PCS Output, Transformer Losses, and Auxiliary Loads
Calculate the difference between aggregate PCS active power and POI active power using specified transformer losses and auxiliary loads.
6
Determining Feasible PCS P–Q Operating Points
Determine feasible active- and reactive-power operating points from a supplied PCS P–Q capability diagram.
