20/03/2017 13/03/2018 - Mooroolbark Mini Grid 22h Off Grid Operation Proves Sharing Renewable Energy Alleviates Power Outages

Mooroolbark mini grid's 22h #offgrid operation proves sharing stored renewable energy through the network alleviates power outages for communities: On Feb. 27th, the small residential community in Melbourne’s outer east was smoothly separated from the main power grid, shared stored solar energy from 14 homes among 18 homes continuously for 22h via the isolated AC grid segment, and then was smoothly integrated back to the main grid. AusNet Services ran the trial. A small PowerTec PowerCache® inverter/battery stabiliser forming the grid, balancing generation and load at any moment, and governing the network connection transitions was a key element to the success (See Media Release)

01/03/2018 01/03/2018 - IoT Technology Bridging the Gap Between Utility HV Power Distribution and Distributed Home Energy Systems

Example of #IoT bridging the gap between utility power distribution and distributed energy systems: A PaDECS® IoT-controller/gateway (same as used in homes) monitoring a High Voltage Regulator and integrating it with the IoT control of a community grid battery energy storage system and grid connection, located downstream in the remote town of Cape Jervis. It enables peak-load lopping of the feeder at the substation connection point by the battery located at 10km distance in town. The ARENA-supported project, led by the Uni of Adelaide and SA Power Networks has been delivered by PowerTec. PaDECS uses the Freestyle Technology IoT platform.


20/03/2017 28/02/2018 - Uni of Adelaide and PowerTec Team Concludes the Hot Test of the "AESKB" Battery Energy Storage System

The University of Adelaide team (from left): Gabriel Haines, Alex Lloyd, Assoc. Prof. Nesimi Ertugrul (all UoA, team member Graeme Bell missing), and Michael Jansen (PowerTec), – after concluding the joint hot test with SA Power Networks of the "AESKB" 270kVA/270kWh Battery Energy Storage and Network Control System at the Thebarton university campus. The PowerCache® system is now being deployed to the remote town of Cape Jervis, where it will support a grid segment with combined feeder and sub-station peak load lopping, feeder voltage stabilisation, and autonomous on-grid/off-grid operation.


20/03/2017 27/11/2017 - AESKB System Leaves Bayswater Workshop

Following thorough testing, the AESKB (Australian Energy Storage Knowledge Base) Grid Stabilising Battery Energy Storage & Research System leaves PowerTec's Bayswater workshop. After full-load testing on SA Power Network's network in Thebarton/SA, it will eventually be deployed at Cape Jervis/Fleurieu Peninsula/SA. Thanks to the Uni of Adelaide and SA Power Networks for carrying out the project with us.


20/03/2017 20/10/2017 - Everybody Hertz

Teaming up at the Australian Renewable Energy Agency (ARENA) A-Lab to work on Network Security and Reliability in a future NEM, dominated by renewables, and incentivising non-traditional generation sources to provide grid support with primary frequency control and synthetic inertia. Accurate understanding of the behaviour of various technologies and the NEM is a first step.

20/03/2017 20/03/2017 - EVN Visits Mooroolbark Mini Grid

EVN Central Power Corporation, the electricity distribution and retail company of central Vietnam, has visited AusNet Services' Mooroolbark Mini Grid site to learn more about the Mini Grid stabilisation solution. EVN CPC was interested in the capability of PowerTec's inverter/battery system (PowerCache®) to stabilise networks with high residential solar penetration. The delegation was travelling in Australia facilitated by AusTrade and Freestyle Technology, PowerTec's IoT system partner.


20/03/2017 10/03/2017 - Mooroolbark Mini Grid Successfully Seperated From Main Grid

AusNet Service's Mini Grid trial in the Melbourne suburb of Mooroolbark proves the viability of aggregating the power from home energy systems and a PowerCache® stabiliser to an independent electricity network. Recently, a first group of 8 homes, 6 with residential solar/battery system, were successfully separated from the grid, operated together as an isolated grid and re-integrated without interruption.

22/02/2017: The 18kVA/11kWh PowerCacheTM Mini Grid Stabiliser has been successfully energised and is live on AusNet Service's Mooroolbark Mini Grid Trial network segment. It provides voltage stabilisation, 3-phase/22 homes power and energy balancing, as well as isolated grid voltage reference services to the community, and will enable the participants to share residential solar energy.


18/07/2016: Power Technology Engineered Solutions has been awarded an order by AusNet Services to provide the Mini Grid Stabilisation System (Community level battery, inverter, on-grid/island transfer system and stabilisation control) for AusNet's Mooroolbark residential community Mini Grid project.


22/03/2016: The first project to implement PaDECS is the ARENA (Australian Renewable Energy Agency) funded project AESKB (Australian Energy Storage Knowledge Bank), led by the University of Adelaide. SA Power Networks plan to deploy later in 2016. PowerTec was selected as system integrator and teams with Freestyle as supplier of the control system.


11/02/2016: Freestyle Technology Pty Ltd (Freestyle) and Power Technology Engineered Solutions Pty Ltd (PowerTec) are collaborating to develop a Parallel Distributed Electrical Assets Control System (PaDECS).

PaDECS improves the stability, reliability of supply, and the economics of operating constrained or isolated power grid segments. Such segments typically include distributed generation, renewables, battery energy storage systems or demand control. The benefits are achieved using a network of intelligent devices controlling the power assets within the grid. The PaDECS solution is attractive where conventional approaches to power supply or grid enhancement are costly and where renewables are to be integrated.

Energy consumers can enjoy more reliable, stable supply. Electricity suppliers and grid operators can reduce capital investments required while increasing grid flexibility out to the furthest reaches. Easier and more efficient use of renewable energy sources will deliver environmental benefits.

The companies started collaborating in early 2015 and a formal agreement was finalised in December. Leveraging Freestyle's proven IoT (Internet of Things) platform and PowerTec's distributed power systems monitoring and control experience, the PaDECS project will deliver greater flexibility using new or existing infrastructure.

One of the first projects to implement PaDECS is the ARENA (Australian Renewable Energy Agency) funded project AESKB (Australian Energy Storage Knowledge Bank), led by the University of Adelaide. SA Power Networks plan to deploy later in 2016. PowerTec currently provides project engineering. Freestyle teamed with PowerTec are preferred suppliers for the control system.


10/10/2014: Power Technology Engineered Solutions has been engaged to follow-through with the realisation of Laing O'Rourke's re-deployable solar-diesel hybrid power plant at the APLNG construction camp in Combabula/QLD. PTES works in an Owner's Engineer role for the Control Systems Integration and aspects of the solar electrical system.


13/08/2014: Power Technology Engineered Solutions has had the opportunity to support its client Laing O'Rourke with the feasibility study and basic electrical integration & control design for its fully re-deployable large-scale solar-diesel hybrid power plant. The project has recently received ARENA funding (ARENA backs "world first" mobile solar-diesel plant).
