Main results from Risø's wind-diesel programme 1984-1990

The report presents the results of the wind-diesel work done in projects at Risø National Laboratory during the years 1984 - 90. including important earlier publications as appendices. The projects were funded by the Energy Research Programme (EFP) of the Danish Ministry uf Energy and the Nordic Council of Ministers (NCM). and the partners in the original joint project were Rise National Iaboratory, Denmark, and Chalmers University of Technology, Sweden. As pan of the first project Chalmers constructed and laboratory tested an advanced wind-diesel-battery system with variable speed operation of the wind turbine, while Risø established a flexible and versatile wind-diesel test facility and held tested Chalmers system. As part of the subsequent EFP projects Risø designed and constructed a simple wind-diesel system without storage, characterized by several innovative features. This concept was part of a "simple wind-diesel systems strategy", in which immediate cost-effectiveness is ensured by the simplicity and reliability of the design. Dynamic computer models were developed for system design and analysis purposes, and a general logistic computer model was developed for the determination of fuel savings and power supply capabilities for a number of system configurations. In addition to a considerable body of experience the main results of the activities are:
• A versatile wind-diesel test facility and a proposed standard wind-diesel test procedure
• Two wind-dicscl systems at each end of the spectrum of configurations
• Computer models for logistic and dynamic modelling
The trends in current wind-diesel development are covered by the NCM and EFP projects in that the two systems represent the very simple system concept, believed to be a presently economically optimal configuration, and the very sophisticated concept believed to be a future optimal configuration.
