The previous two parts of the paper introduces the function design and support layer of the dynamic simulation platform for power market & power system（DSPMPS） separately. According to the software demands described in the function design， applications can be created to describe the phenomenon led by generalized congestions， to support strategy searches in a visualized way， and to be fully scalable to meet future needs by using the application programming interface and tools of the support layer. The steps to build an application in the application layer start with the extraction of frequently used models from typical problems relevant to the dynamic interactions between power systems and power markets. The hierarchy of the simulation component library composed of many components in different fields is then designed systematically to improve their reusability. The FASTEST， a powerful software package to analyze power system stability in a quantitative way， is integrated as the DSPMPS' analysis engine for physical system studies， which is also an example of the integration of other software platforms into the DSPMPS. Finally， the simulation markup language is used to write scripts and do configurations for multi-player simulation experiments. The merits and unique features of the platform are introduced through a typical experiment process.
