Transactive energy system

The rising of distributed energy resource (DER) e.g. rooftop PV solar system, wind system and energy storage system, and load demand response bring both opportunities and challenges to the power grid. Coordinating decentralised DERs is important. The purpose of transactive energy (TE) system is to coordinate DERs at the distribution level and encourage consumers and prosumers to participate in electricity market by providing economic incentives. TE system enables customers and prosumers to sell the surplus energy to their neighbours. This thesis represents research on TE system in aspects of structure, technology, economics and participants. The impact of TE system in Australia’s electrical standard and electricity business mode is also explored. Moreover, based on research findings, a TE system model for Australia is proposed. The key findings of this project are: • TE System is a method to relieve electricity congestion. • The power flow (distribution level) and transaction in TE system are bidirectional. • TE system is customer-oriented and offers more choices to customers/prosumers. • The new distribution system operator (DSO) plays a key role in coordinating DERs and end-users. • Undertaking a TE system demonstration project in Australia is suggested
