Coursework brief

The required work in this assessment consists of a microgrid design. Here you should decide upon the following:

a. Purpose of the microgrid (to supply an isolated village, a hospital, a set of University buildings, a datacentre, a military base, etc).

b. Type of microgrid (grid connected or standalone)

c. Location of the microgrid

d. Demand profile characteristics including variability if applicable

e. Types of energy sources to be considered for use in the microgrid and their profile (e.g. sun irradiance data, wind speed data, etc)

f. Specific equipment sizes and quantities of equipment items to be considered

g. Other equipment to be used

h. All relevant cost information, including equipment costs, maintenance and operations costs, residual values, fuel costs, interest rate, electricity tariffs, etc.

i. Method and criteria to be used to optimise the configuration, including the choice of a software tool. Here the software tool could be generic (such as MATLAB or Excel), or it could be specialised (such as HOMER)

Please note, the microgrid to be designed must have at least the following components: solar PV generation, a diesel generator and battery energy storage.

The study must also include a sensitivity analysis with respect to a key variable of your choice, which could, for example, be the fuel cost.

You should discuss in your report the main qualities and any limitations of the resulting design. You can use information from the scientific or commercial literature, as well as online tools, to define items such as the demand profile, equipment characteristics, resource information, but you must not copy all the details of an existing design case study on microgrid configuration (published or not), nor should you use an example previously seen in class. In other words, your design needs to be unique to your report and not previously done by anyone else.

General guidance and Information

You should produce a report addressing the coursework brief given above. The maximum word count for the main body of your report is 1500 words, excluding the cover page, tables, figures, references and appendices.

You should format your report using the IEEE Conference Template, which you can download from:

https://www.ieee.org/content/dam/ieee-org/ieee/web/org/conferences/Conference-template-A4.doc

You are only allowed to work on your own, no team work is permissible.

The report will be marked out of 100 marks.

For the marking criteria, please turn over.
