The aim of the proposed project is the construction of a facility to study the behaviour of a hybrid diesel-wind turbinephotovoltaic generator system with a battery pack as storage/ballast, feeding a small isolated grid and to train personnel from electric power utilities in such operating systems.
The test facility constructed during this project is unique in Europe. The project team has developed both a software and a hardware simulator for long-term analysis of hybrid system behaviour. The tests identified opportunities for fuel savings and optimising the design of the system by using different configurations and control strategies. The efficiency of the system varied considerably depending on the configuration and the control strategy used. This indicates that it is essential to understand the interactions between the generators used and the load distribution to achieve maximum efficiencies in hybrid systems.
The use of this facility, unique in Europe in the planned form, will be of great help in solving problems of sizing renewable energy systems for investment economy and cooperation for operating economy and reliability, with the conventional sources as part of hybrid plants. This system is able to simulate not only long term behaviour, but also to reproduce short term transient phenomena which have lately attracted much interest. For longer period or larger scale simulation, a logistical computer model will also need to be developed which will include all the above-mentioned components. This model will draw on the experience of the partners who realised similar models in the past and will include novel features especially regarding the control strategy capibilities. The final aim of the project is the use of the simulator to model two existing small grids. The results of such a study will provide the data base for the validation of the computer simulation code and also become available as a data set to anyone interested in validating similar models. With both hardware and computer simulators running, a first attempt to train a small group of isolated power station dispatchers will be carried out to provide experience and underline possible troubleshoots in the projected use of the facility as training school.
