Abstract
Within new projects in the future in supplying local areas, a Power Operation and
Power Qua1ity Management System (POPQMS) must be developed. In order to model the
parts of network with regulation programmable opened software in Matlab – DynaSolv was
developed. DynaSolv can simulate multi-machine dynamics. The paper describes various
principles of penetration synchronous machine type DGS into distribution network. This
study provides possible complex analysis view on DGS stability issues, which can answer the
possibility of connection.
