Design and implementation of an active distribution network simulator for loss minimization considering distributed energy resource integration

The integration of distributed generations (DGs) has a significant influence on the operation characteristics of distribution system, especially power losses. In this paper, a distribution system simulation framework with DGs integration is proposed, which can achieve the coordination goal between DGs integration and traditional VAR regulation devices, with the goal of minimizing power losses. In the simulation platform, three-phase steady state models of various forms of DGs are studied, such as synchronous generators, asynchronous generators, power electronics interfaces and doubly-fed induction generators (DFIGs). Then the three-phase power flow method with DGs integration is developed and VAR optimization method is exploited. The proposed method is applied on a three-feeder test system and the simulation results show that with regulation of DGs, the power losses are reduced.
