Co-generation systems have been spreading rapidly over the past 10 years in Korea and most of these systems are interconnected with electric power systems. However, better control and protection models are still needed for analysis of these systems to ensure stable operation with the grid. This paper proposes improved EMTDC models for control fad protection analysis of grid-connected co-generation systems. Through on-site characteristic testing, the models were developed and the model parameters were determined. The models were applied to a field co-generation system, and analysis of control and protection was performed showing a good match to the simulation results.

Recently, the concern for environmental issue has been rising in the world such as global warming and breaking of ozone barrier by exhausting carbon dioxide(CO2) and Freon. In this situation, Photovoltaic(PV) and hydrogen energy system for utilizing clean and renewable energy was highlighted to contribute very much against the global warming prevention. Until now, authors have studied EMTDC model Development of Solar-powered Hydrogen production system and manufactured the 600W class actual PV-SPE system. Which was established in 2004 to produce highly pure hydrogen energized by PV power generation system. Sooner, authors will establish 100kW class PV-SPE system. Economically, this system produce large amount of hydrogen. In this paper, all data of 100kW class PV-SPE system will be simulated by using PSCAD/EMTDC.
