Description
Microgrids are small-scale electrical energy grids that can operate either autonomously or interconnected with other grids. This subject aims to provide students with a knowledge and understanding of the design principles and control strategies for sustainable microgrids. Efficient, reliable and sustainable energy is a key feature of global change and energy protection systems such as microgrids play a major role. Students learn about basic microgrid background and structure; distributed generation; energy storage (capacitors, batteries, fuel cells, etc.); converter types and functions; power dispatch and energy management; hierarchical control structures; microgrid modelling; microgrid stability; microgrid protection; storage technology; and battery characteristics. Case studies are used to illustrate the concepts discussed.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | Describe sustainable microgrids and the challenges of implementing them in communities. (B.1) |
|---|---|
| 2. | Design and evaluate new microgrids considering consumer behaviours and technical requirements to improve the resilience of power supply. (C.1) |
| 3. | Analyse cost and benefits of microrgid technology to support low-carbon power system operation and energy efficient operation. (D.1) |
| 4. | Evaluate the design of a current microgrid to determine its reliability, sustainability and possible improvements. (C.1) |
Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):
- Socially Responsible: FEIT graduates identify, engage, and influence stakeholders, and apply expert judgment establishing and managing constraints, conflicts and uncertainties within a hazards and risk framework to define system requirements and interactivity. (B.1)
- Design Oriented: FEIT graduates apply problem solving, design thinking and decision-making methodologies in new contexts or to novel problems, to explore, test, analyse and synthesise complex ideas, theories or concepts. (C.1)
- Technically Proficient: FEIT graduates apply theoretical, conceptual, software and physical tools and advanced discipline knowledge to research, evaluate and predict future performance of systems characterised by complexity. (D.1)
Contribution to the development of graduate attributes

Teaching and learning strategies
This subject runs a series of workshops. Each workshop will include different activities including a short lecture, question and answer session, problem solving activities, laboratory training and working on a design-based group project. This subject will introduce microgrid (MG) components (distributed generation and energy storage), MG modelling, MG operation and control, protection, stability analysis and controller design. The design projects will develop your technical expertise, problem solving skills, design skills, and research skills. Other activities are seminars and discussions including collaborating with peers and finding answers to student questions on technical content and project design. Prior to the block teaching activity, you are required to study the subject topic notes, the design project requirement, and associated readings and prepare questions relating to the content. You are advised to use both the subject topic notes and recommended references.
All students are expected to attend all workshops, as one builds on to the next. The teaching aims to provide you opportunities to engage in MG modelling and analysis, operation control, MG design, and sustainability analysis. Workshops are designed to encourage interaction between students and the lecturer. You will have the opportunity to raise any doubts and questions in relation to the workshop topics and in particular the design projects, and receive the feedback from the lecturer. Continuous feedback will be given in combined forms of oral, written, email, online, etc., during workshops and through assessment tasks.
Problem solving questions relevant to the workshop topics will be solved interactively in groups. You are encouraged to work through exercise problems and practise on the case studies in the recommended references. You are required to solve the design projects collaboratively within your assigned group. The laboratory exercises are part of the design training where you have more opportunities to discuss your questions with the lecturer and/or tutors.
Content (topics)
- Basics of microgrid (background, system components and functions)

The content will be taught in three modules:
- Topic 1+2 (Microgrid energy storage)
