Australian operators conduct virtual power plant trials
The Virtual Power Plant (VPP) supplies electricity and frequency conditioning services to the Australian grid, which will be demonstrated through a new integrated pilot project.
The Australian government has indicated that the Australian Power Mall Operator (AEMO) has received $2.46 million ($1.75 million) in funding from the National Renewable Power Organization AERNA for a period of 12-18 months.
Australia now has some VPPs that are in operation or under construction. Dozens of distributed power (DERS), especially household photovoltaic + energy storage systems and energy storage systems required by industry and commerce, use batteries and are equipped with bidirectional currents to connect them to the grid. The available capacity generated by these distributed energy storage systems connected via virtual power grids (VPPs) is called according to the needs of the grid company and the operator.
That is, the grid side resources are handled, and the traditional and centralized power generation effect is achieved in terms of security grid, maintenance of power security, supply and quality, etc. AEMO will invite Australia's pilot vpp project to participate in recent demonstration activities, including Sonnen. World suppliers such as Tesla and Sunverge.
Using this method to operate distributed power (DERs) will enable AEMO to explain how to develop appropriate regulatory and operational processes, and ARENA's funding will enable mall operators to “accelerate the upgrade of AEMO systems and processes. VPP can integrate smoothly when it comes to business planning."
Network reliability has increased significantly, and shopping mall competition has intensified
AEMO CEO Audrey Zibelman served as Commissioner and Chairman of the New York State Public Service Commission (NYPSC) and has extensive experience in the power store, which plays a key role in the development of the National Reform Power Vision (NY REV) policy and strategy. . Zibelman joined AEMO in 2017 and said that the latest activities will prove the value of distributed power integration.
“Australia's dynamic format is transforming into deeper penetration into customer-grade renewable power generation and energy storage. Our focus is on building a two-way system to improve the safety and value of vpp participants and the entire power system.” Zibelman explains .
AEMO believes that by 2022, Australia will have up to 700 megawatts of resources to participate in VPPs. ARENA CEO Darren Miller indicated that the National Electric Power Mall (NEM) is a large-scale power shopping mall connecting five jurisdictions in Australia, serving approximately 9 million customers. The size of such a large planned customer is also good for VPP. opportunity.
He added that AEMO will increase exposure through VPPs and will test how it works in the mall to maximize customer and system revenue. This experiment will let us know how to better integrate a larger planned VPP in the next few years. As we transition to a more dynamic power system, VPP will play a very important role in handling customer power assets such as rooftop PV, batteries and electric vehicle charging.
“VPPs can see the improvement of network reliability and the improvement of the competitiveness of shopping malls, which will ultimately benefit all customers”
Use of VPP in other regions: US family photovoltaic company Sunrun recently signed a contract to operate approximately 5,000 energy storage devices around New England, and supply 20MW of electricity to the grid; Advanced Microgrid Solutions (AMS), a commercial and energy storage supplier, recently It shows that in 2018, the company has built VPP harmoniously in its own industrial and commercial system and has supplied 2GWh of grid service to a California utility company.
