Grid Integration Laboratory (GIL) at Indian Institute of Technology, Bombay, in collaboration with Monash University, Australia, through the IITB-Monash Research Academy, has developed a new, realistic approach to develop a real-time reduced steady-state model of an active distribution network (ADN) using synchrophasor measurements that reduces the computational effort of modelling intrinsically complex ADNs.
Owing to the naturally stochastic behaviour of DERs and the time-varying composition of loads, it is paramount to develop a real-time reduced ADN model which can adapt to operating point variations. Such models facilitate much-needed co-simulation of the bulk power system and multiple ADNs for grid support applications. With the advent of distribution-level phasor measurement units (D-PMUs), the synchrophasor data are employed to derive the reduced model parameters in real time and track the time-varying ADN operating point. The proposed approach develops a general three-phase, four-wire reduced model which can replace any arbitrary feeder configuration confined within D-PMUs. DOI
