This research was carried out to establish a design methodology of integrated renewable energy systems and to demonstrate/evaluate its performance throughout experimental study. Major results from this project are as follows :1. Medeling(1), We have coded integrated RE systems which include Geo-HP, PV, wind turbine and made it possible to evaluate its transient performance and cost/environmental effect.2. Evaluation of response of the Geo-HP system(1), The performance of Geo-HP system with water storage was evaluated by a simulation code. (2), The flow of water and heat in the permeable formation was modeled by means of FEM.3. Investigation of the model(1), Optimum system and its performance was evaluated to some model field in Tohoku area. (2), Predictive model using previous information on demand/supply.4. Data collection and simulation at model fields.(1), Three model fields were selected in Tohoku area and renewable energy systems were designed to each site. (2), Historical change of the energy systems were made at a village. (3), FS on introduction of the RE systems to a new campus of Tohoku University was made.5. Demonstrative study(1), A model system of PV, wind turbine and Geo-HP was build in Tohoku University and its performance and operating style was experimentally investigated. (2), A system with a micro-hydro and Geo-HP at Higashi-Hachimantai field was designed and its performance was evaluated by simulation.
