Postcard From the Future: VPPs in Australia

By Peter Asmus on Sep 25, 2019 12:30:37 PM

Guest blogger Peter Asmus of Navigant Research writes about the evolution of the virtual power plant market in Australia. 

Australian consumers boast one of the highest per capita consumption rates of electricity in the world (even greater than the U.S.). These consumption levels translate into flexible load resources ideal for aggregation and optimization into virtual power plants (VPPs).

What is a VPP? Think of it as a conglomeration of many distributed energy resources (DERs -- loads, but also generation, batteries and electric vehicles -- that can be combined into a pool whose sum of parts’ value is far larger than these DER assets offer individually. With sophisticated artificial intelligence software, these resources scattered across the grid can be combined “virtually” to provide the same services as a traditional 24/7 power plant -- but at much lower and environmental cost.

Load, the oft-overlooked distributed energy resource

INTRODUCTION:

Researchers at DNV-GL did a fine report for the New York Independent System Operator a few years ago. Titled A Review of Distributed Energy Resources, it offered this definition of the various distributed energy resources (DERs) examined in the report:

“… DER technologies are defined as ‘behind-the-meter’ power generation and storage resources typically located on an end-use customer’s premises and operated for the purpose of supplying all or a portion of the customer’s electric load. Such resources may also be capable of injecting power into the transmission and/or distribution system or into a non-utility local network in parallel with the utility grid. These DERs include such technologies as solar photovoltaic (PV), combined heat and power (CHP) or cogeneration systems, microgrids, wind turbines, micro turbines, back-up generators and energy storage.”

Granted, the research team did acknowledge that some sources – including the New York Public Service Commission – included customer load in its list of DERs, but load wasn’t one of the DERs covered in the report. That’s too bad because load can hold its own against other DERs for a variety of grid-supportive purposes.
