This project was concerned about simulating wind-diesel systems with differing diesel generators, wind generation and energy storage. The simulating tool that was used in this project was Microsoft EXCEL.

A basic EXCEL ‘one hour’ energy flow model with one type of diesel generator was provided at the start of the project. The ‘one hour’ model contains average wind and load data recorded at each hour of the year.

This basic model was further developed to include:
Three types of diesel generator and,
Energy storage

Other than the basic ‘one hour’ model, different versions of the EXCEL model were also developed, which include:
‘Half hour’ model and,
‘Ten minute’ model

The only difference between the ‘half hour’ model and the ‘one hour’ model is that the average wind and load data are different. Therefore, there were not many changes in programming the ‘half hour’ model from the ‘one hour’ model. However, for the ‘ten minute’ model, the operation time of the diesel generators must be considered. Diesel generators do not turn on and off every 10 minutes and hence, the model must be programmed so that the diesel generators operate every 30 minutes or an hour. However, this was not done in the project due to time constraints. A ‘time step’ model was created instead to allow average wind and load data for any time step i.e. 2 hours data, 45 minutes data, 15 minutes data etc., to be pasted into the model.

The user-friendliness of the program was also improved to give better understanding by including simple instructions for users to use the program more conveniently.

The final enhanced one hour model with one type of diesel generator was then compared with HOMER to see how the results differ. The two programs are very different to each other in terms of both input details and simulation results.
