Energy Studies – Assignment 2:
An isolated island far from the mainland is looking at switching to a renewable electricity generation. Resource data for Wind (onshore and offshore), Solar and the load profile for the island are provided in the file “Resources.xls” on Vision. The island also appreciates significant elevation difference and many plateaus across its surface (elevation map of island on Vision).
Based on this data,
1. Try to find a configuration of renewable generation technologies (wind, wind and solar, solar only, hydro, biomass,) that provides electricity for the island based only on the yearly consumption.
[10 marks]
2. Make a detailed analysis of the load profile. Does the electricity configuration of your results from question 1 still give a stable power supply?
To answer this question, look at:
• The seasonal variation (winter and summer) in your electricity generation; What is the seasonal variation (winter and summer) in your load data?
• Does your configuration provide enough electricity during both winter (December to March) and summer (June to September) months?
• The days with the highest and the lowest demand in the year, respectively, to test your system.
Your system should provide enough electricity for every hour throughout the year; For a stable grid you need to cover both periods of surplus when you generate too much electricity (where does it go?) as well as cover for periods where you do not generate enough electricity (should people sit in the dark of can you provide an alternative?).

3. Suggest a solution for a stable power supply on your island. This includes electricity generation, energy storage and supporting demand management measures.
• Choose an appropriate configuration for electricity generation.
[30 marks]
• Chose the most appropriate energy storage technology four your grid and justify your choice
[15 marks]
• What size do you need for your Energy Storage to have a stable grid?
