Development of simulation platform of distribution systems with DGs and SVR for voltage control studies

In this paper, we develop the simulation platform of the distribution systems with distributed generations (DGs). The detailed simulation models of a DG and a step voltage regulator (SVR) are developed as PSCAD user defined model (UDM). The control schemes of SVR and DGs to regulate the local voltages are proposed and implemented as a function block in the PSCAD platform. Some case studies to verify the effectiveness of the control schemes are performed in the developed simulation platform.
