Optimisation of distributed energy resources

People

Description

Distributed energy resources (DERs) are changing the way how electricity is generated and managed. Traditionally, electricity has been generated by big power plants. Today, it is also starting to come from DER located in millions of homes and businesses. Common examples of DERs include photovoltaic systems, battery energy storage systems, electric vehicles, and home energy management technologies.

The demand for DERs in Australia is expected to grow in the next years. Energy Networks Australia estimates that by 2050, DERs may contribute up to 45% of Australia’s electricity generation capacity. A high number of DERs may significantly impact the operation of the Australian power system. For instance, the operation of DERs may generate voltage and congestion problems in the distribution networks, if not well managed.

Goals

The goal of this project is to develop an optimisation model to plan, upkeep, or operate a power system characterized by a high integration of DERs. The optimisation model may address technical, economic, or environmental aspects, depending on the interest and motivation of the student. Examples of optimisation models are:

  • Bidding optimisation models for DER aggregators;
  • Portfolio optimisation models for DER aggregators;
  • Distributed optimisation approaches for energy system applications;
  • Planning optimisation models for distribution networks.

Requirements

  • Knowledge of optimisation.
  • Programming skills, such as python.
