A transactive energy model – from local to global efficiency

Indra has developed a transactive energy framework on which use cases can be modelled.

The new decentralised energy paradigm with prosumers alongside utilities and a host of new players such as demand response aggregators needs new innovative tools for its functioning.

Gone are the days of the utility as the sole generator and user of data. Now, data is being generated by and needs to be shared among multiple parties for management and settlement across the network. In addition, with the proliferation of edge and grid devices there is both a growing volume of data and its requirement is increasingly time critical.

Building up this ‘transactive energy’ marketplace is no simple task, given the complexities of this market and particularly during the transition when current and new business models need to co-exist.

“These developments are bringing new challenges to utilities but also new opportunities,” says Juan Prieto Moris, Head of Prosumer Solutions at technology company Indra. “We are facing a complexity that until now has never been handled.”

Moris recommends that players should design a roadmap for developing their transactive energy use cases. In a presentation at the Engerati Meet on Transactive Energy and Blockchain, he outlines Indra’s transactive energy modelling framework and how it is being leveraged in real life projects.

“The solution for achieving a resilient and highly configurable system is software – a unified open software architecture that is able to provision applications and services on any part of the network and with the capability to manage real-time machinery and information as well as human-in-the-loop processing,” says Moris of the requirements for a transactive energy platform.

“This will enable monitoring, control and visualisation for prosumers, aggregators and system operators and provide a common space for them to collaborate with a real-time snapshot of all the devices and how to schedule them.”

Moris also notes the potential of blockchain in the settlement process: “Blockchain fosters collaboration and provides trust and transparency and these features are necessary in a context where transactions occur between a wide variety of participants.”

Transactive energy models

Moris says that in the framework four different areas are identified over which prosumers and the grid are integrated to support transactive energy markets. Each of these can interact with the others through different inter-combinable building blocks containing the key components and use cases of any particular model.

“Over this framework, multiple different energy models can be designed and discussed with customers and partners. We see visual tools as enhancing collaboration and ensuring successful orchestration and we need both to build the transactive energy roadmap.”

As an example, Moris presents an application of the framework to a microgrid project at Monash University’s Clayton campus in Melbourne, Australia.

“This includes a wide variety of use cases within the new transactive energy models,” he says of the project, which is expected by 2020 to be generating 7GWh of electricity and forms part of the university’s drive to achieve zero net emissions by 2030. The microgrid is based on Indra’s InGrid Active Grid Management IoT platform which was developed to provide dynamic distributed and smart medium and low voltage grid operation. Among use cases under development for the microgrid are predictive asset maintenance control and a peer-to-peer trading market.

Currently, the framework is being applied in some 15 projects in all elsewhere in other parts of the world, Moris notes.
