Dynamic simulation of CIG in large unbalanced distribution systems using an open source tool

This study explains the underlying concepts and implementation details of using an open source distribution analysis tool – OpenDSS to conduct dynamic simulations of converter interfaced generation (CIG) in large, realistic power distribution systems. The dynamic models of different types of CIGs are derived and written into the dynamic-link library (DLL) to be called by OpenDSS during simulation. The DLL development is illustrated in detail...
