A hybrid simulation tool for penetration studies of distributed generation in smartgrids

This paper presents a hybrid simulation tool that combine fast analysis of quasi-static and electromagnetic transients electric models. The interaction between the two programs are carried out by controllable current and voltage sources which are used to represent the external and the detailed systems, respectively. A server controls the data communication between the two simulation environments. The proposed tool will be used here to simulate the integration of three distinct photovoltaic plants into a 13-bus electric distribution network. The results obtained with the proposed simulation strategy are compared with the ones carried out with detailed models, fully implemented and simulated in an electromagnetic transients program. Results demonstrate the accuracy of the proposed simulation strategy as well as the the lower simulation timings.
