General Modelling Method for the Active Distribution Network with Multiple Types of Renewable Distributed Generations

With a proliferation of diverse types renewable distributed generation (DG) into the distribution network, an equivalent model active network (ADN) is extremely important, since detailed modeling whole ADN much more complex and time consuming. However, different studies developed structures ADNs, which are difficult to be applied in power system simulation. At same time, DG’s low voltage ride through (LVRT) control was not considered existing model, may lead large modelling error. In this paper, general for with significant amount DGs, based on two-step method. Step one, motivated by dynamic similarities between doubly-fed induction generator (DFIG)-based wind turbines, direct drive permanent magnet synchronous (DDPMSG)-based photovoltaic (PV) generation, structure DG initially developed. Then, aggregation method nonlinear subsystems converter’s current limits presented. two, represented paralleled composite load validated, actual penetrations disturbance degrees. The simulation results show that our outperforms others acceptable errors.
