Engineering tools for wind-diesel systems


To develop design tools for wind/diesel systems comprising user friendly software packages. These are to cover the modelling of overall (ie logistic) performance and the dynamic modelling of systems. All code will be subject to validation against experimental data. It is intended that the programs will run on a PC or similar.
Wind Diesel is the term applied to systems in which wind energy accounts for a significant proportion of the total energy supplied such that the wind energy input has a marked impact on the operation of the diesel plant.

Previously wind diesel modelling work has been closely coupled to specific systems. The aim of this project has been to equip the design engineer with a set of tools for the general design, development, specification and assessment of wind diesel systems. A suite of models for the modelling of logistical aspects of wind diesel systems is now substantially in place. A modular dynamic model capable of modelling a very wide range of system types and configurations has also been extensively developed. Together this software should do much to bridge the gap between previous research oriented modelling and the engineers requirement for a general design tools package.
In the context of this project the term wind/diesel is understood to mean an electricity supply system combining wind and diesel generation in which wind energy accounts for a significant proportion of the total energy supplied. The interaction between the major system components; wind turbines, diesel generators and energy storage, taken together with the effects of the control system, present a complex problem. A wide range of different wind/diesel system configurations and in particular, a range of different storage technologies with contrasting technical characteristics need to be dealt with. The proposed research programme aims to accomplish its objectives by relying heavily on the work already undertaken as part of significant national programmes and on the research carried out under IEA Annex VIII, on wind/diesel systems.

A) Logistic Design Tool package

Specifically the Design Tool package will be based on existing wind/diesel models, and calculation procedures which exist in the participating countries. Before inclusion in the "Design Package" these modules will be thoroughly validated against data to be made available from wind/diesel systems accessible to the collaboration. The various modules (national computer codes) will then be brought together in a user-friendly environment. The final package will advise the system designer which modules are appropriate to specific applications and give guidance on the strengths and weaknesses of the different options. Results will be provided in a standard format.

B) Dynamic Model

The Dynamic system model will be based on existing models, in particular on EFI's model developed to investigate some specific system configurations. The already existing verification of the models will be reviewed, and additional verification against measured data will be made, in order to clarify to what extent the basic equations of the models need modification and/or extension. The computer model will consist of a number of Fortran77 routines designed for use in the CYPROS/SIM simulation program package, which will reduce the actual programming effort significantly.
