A Novel Passive Islanding Detection Method for a Microgrid Using Instantaneous Energy

Abstract: In this paper, a new passive method is proposed to detect islanding of distributed generation using the instantaneous energy that is calculated at the target distributed generation DG or PCC. The instantaneous energy feature can be used to detect islanding status. Instantaneous active energy during Event (IAEDE) and instantaneous reactive energy during event (IREDE) computed from the integration of the Instantaneous active power during the event (IAPDE) and the integration of the instantaneous reactive power during the event (IRPDE). The rate of change of angle (ψ) between them calculated for islanding detection (ROCOψ). The proposed technique has detected the islanding in a rather short time after islanding occurrence. The simulation results showed that the proposed technique could distinguish islanding from other similar events such as load switching at PCC and fault at PCC. This technique can detect islanding efficiently even with zero power mismatches between loads and DGs and hence, reduces the non-detection zone and does not mal operate during similar events. It is more reliable and dependable and the detection time is less than 0.5 sec. Keywords: Distributed generation, Passive islanding detection, Non-Detection Zone, Instantaneous Energy.
