The existence of distributed generations (DGs) deviates the unidirectional nature of power flow, and the distribution system no more remains a passive system. The explosion of DGs at distribution levels carried the concept of the active distribution system (ADS). The interconnection of distributed generation sources into the distribution system provides numerous challenges to distribution load flow in terms of modelling of various power delivery and power conversion components. General power delivery components are symbolized by their impedance or admittance, depending on the requirement of
