Case Studies & Papers
As part of our commitment to building industry knowledge, papers, presentations and case studies stemming from the project will be made available here.
- Basic Operation of the AESKB Test Platform
This report provides an introduction to battery energy storage systems, and describes the basic operation of the Australian Energy Storage Knowledge Bank's Mobile Test Platform. Charging and discharging operation is examined, the battery's cell voltage and state of charge is explored, inverter efficiency is measured, and the energy capacity is demonstrated.
There are two data sets associated with these files. The first covers 20kw charge and discharge test data. The second covers full power charge and discharge data. Both data sets include power quality data aggregated every three seconds.
- Power Factor Control with the AESKB Test Platform
This report explores reactive power, power factor, and the ability of the Australian Energy Storage Knowledge Bank's Mobile Test Platform to control these quantities. Reactive power provides no useable power, but increases the load on the power system and reduces the amount of real, useful power that can be delivered. These concepts are explored with the aid of the power triangle, P-Q unit circle, and real waveforms.
The following detailed data sets (in tdms format) are available:
- Power factor control and P-Q circle operation, with inverter and generation bus total power quality data aggregated every three seconds. Download the data set
- Waveform data when reactive power increased during the P-Q circle operation in Thebarton 2017. The waveform is 3 seconds in length, containing 1.5 million samples per inverter channel, 300 thousand samples per channel. Download the data set.
- Waveform form idle inverter before P-Q circle captured once the inverter is connected to the grid and left idle and also captures the inrush current during connection. The wave form is 4 seconds in length, containing 2 million samples per inverter channel. Download the data set.
- Microgrid Islanding with the AESKB Test Platform
This report explores the ability of the Australian Energy Storage Knowledge Bank's Mobile Test Platform to function as an islanded microgrid. Anti-islanding tests are shown, followed by bumpless segregation and reintegration of the microgrid with the main grid. The segregation and reintegration events are shown in detail, including the voltage, frequency, phase and rate of change of frequency (ROCOF) during these events. Download the power data from the grid, generation bus and inverter (in tdms format).
- Power Quality of a Battery Energy Storage System (Bess) with Nonlinear Load
This report looks at the operation and power quality of an islanded microgrid with non-linear load. The Australian Energy Storage Knowledge Bank's Mobile Test Platform operated as an island connected to only the Thebarton Wind tunnel variable speed drives. The test provides an example of what future microgrids may look like under the worst-case scenario of only power electronic devices, with distorted and non-sinusoidal voltage and current. The power quality of the system is described using a number of standard power quality measurement techniques from IEC 61000-4-30 and IEEE 1459, including discussion on the limitations and discrepancies between the different measurement methods. The following data sets (in tdms format) are also available:
- Energy Storage and the Future of the SA Grid
On the 25th of November 2016, as part of an official launch of the knowledge Bank website, the Energy Storage Knowledge Bank team held an event at the SA Art Gallery featuring speakers from Morgan Stanley, SA Power Networks, ZEN Energy, Adelaide University, Electranet and Power Technology Engineered Solutions.
Topics ranged from the impact on energy storage systems on the distribution network (presented by SAPN), opportunities in Energy Storage (Adelaide University), frequency regulation (ZEN Energy) and the impact of the internet of things on power assets (Power Technology Engineered Solutions).
