ELEC3160 Principles and Design of O Grid Power Systems Assignment 2: Optimisation using Homer

1 Introduction

The main assessment task in ELEC3160 is to design your own o grid power system. This project will require you to essentially carry out three tasks:

1. identify energy sources on the site that may be able to be converted to electrical energy;
2. model loads;
3. select the sources and mix of sources which make the most 'sense' and;
4. Determine if the system will actually satisfy requirements in both steady state and dynamically.

The three assignments in the course build skills to enable you to complete the FInal project.

The assignments have been given a nominal weighting to (a) encourage you to develop the skills early and (b) to enable you to build up some marks progres- sively to take some pressure of the project and the nal examination.

This assignment involves determining resource (energy) availability at a speci c site which may be able to be utilised in an o grid power system.

2 Specific Task

This assignment involves selecting the sources and mix of sources which make the most 'sense' and modelling loads or at least modelling load pro les. In order to do this I want you to make use of the simulation tool Homer. Homer PRO is currently being purchsed by the University. The speci c tasks to carry out are then

1.Download and install Homer PRO.

2.Carry out the 'tour' for Homer.
(a)Set the location to be the site of Assignment 1.
(b)Follow the rest of the tutorial.

3.Modify the system to include at least one other energy source that you considered in Assignment 1.
(a)Carry out the simulation on the modi ed system
(b)Analyse the results including the sensitivity results

4.You are to write a brief technical report outlining your ndings.
(a)You must have a `proper' report structure.
(b)The grammar and style should be appropriate.

5.You should submit the report via Turnitin on Blackboard.

3 Marks

The assignment is work 10% of your nal mark for the course. Marks will be awarded as outlined in the Rubrick shown Table 1. Note that the nal mark will be weighted by Task 1. That is,
r M    n=4

Where,

M is the nal mark for the assignment
Mn is the mark for Task n
For example, if the mark for task 1 was 49% an dthe marks for tasks 2 to 4 added up to be 45 then the  nal mark would be
M = 2 × 0.7 × 45 = 63
