Abstract:

This paper provides a data-driven phase identification approach for a power distribution system with high photovoltaic (PV) penetration in both wye-connected and delta- connected loads. The proposed approach is built upon concepts in information theory, followed by a mathematical proof to solve the challenge when the penetration of PV is up to 100%. The proposed method is based on a joint analysis of the event signatures between the smart meter at the customer side and those at the feeder head. The high accuracy of the proposed method is confirmed by conducting case studies on the IEEE 34 bus test system with different load profiles with different PV penetration levels. The maximum distinguishable number of customers for the proposed method is also estimated based on theory of probability.
