Voltage unbalance assessment in secondary radial distribution networks with single-phase photovoltaic systems
A voltage unbalance sensitivity analysis is presented in a SRDN with SPPVSs. Current requirements of maximum size to be connected of SPPVSs in SRDNs are checked. A stochastic assessment method accounts any random combination of SPPVSs in a SRDN. The assessment of voltage unbalance is made on a 10-min basis throughout one year. Results present maximum sizes of SPPVS to be connected based on PV penetration.
