Practical power distance test tool based on OPF to assess feeder DG hosting capacity

Voltage performance has become a sensitive issue since distribution network operators (DNOs) began to integrate a large amount of distribution generation (DG) in its distribution system. A set of voltage performance design criteria has been established by DNOs but the corresponding analytical method restricts it to exploit more headroom of DG hosting capacity. A methodology based on optimal power flow (OPF) technique is proposed to accommodate a higher level of DG penetration without an advanced distribution system (ADS), which strictly meets the voltage performance design criteria.
