To examine the impact of high PV penetration on voltage profile, power flow analysis can be used to determine the steady-state operating condition of the system [49].When power generated from distributed resources exceeds the load on a feeder or section of a feeder, voltages may rise on that section. In addition, significant aggregations of distributed resources may cause feeder currents to approach or exceed design currents.
