What Software Do I Need?

If you are trialing ez2view, then all the software and documentation you need can be downloaded from this page.

If you have all your own data and you don't need to get any data from us, then again, all the software and documentation is available on this page.

BUT...If you want to obtain AEMO or TNSP data from us then you will need our ez2update data feed. In this case you should install and configure ez2update before you install and configure ez2view. If you think you might need ez2update, then have a look at the ez2update downloads page.

Recent Releases

ez2view Version 4.1.202 - Released December, 2011

This is the current production version of ez2view.

In our last release (November 2011) we added new browser screens to allow you to drill into the detailed information for Constraint Sets and Constraint Equations. In this new release we have added two more browser screens – one for Stations and another for the Interconnectors.

On the Station Browser you can now see:

Enhanced trend charts of recent output, broken down at unit level
Details of the output of each unit in the previous dispatch interval
Fuel type and emissions factors for each unit in the station
Operational attributes for each unit from the MMS database
Participant data for the station
Constraints affecting the station at the moment

On the Interconnector Browser you can now see:

A trend chart of the recent flow and limit values
The constraint equations affecting the Interconnector in the current Dispatch interval
Operational attributes for the Interconnector from the MMS database

We have also made a number of other interesting enhancements to the product:

With permission from AEMO we have included the transmission diagrams from the NTNDP as a tab on each Station Browser to help you place events in the NEM in the context of the transmission network.
ez2view is now aware of the latitude and longitude coordinates for each station and we have used this data to give you an automated link to Google Maps to display the location and satellite imagery of each station.
We have upgraded the chart controls on all the browser screens, so hovering over the charts now gives you a reading of the values under the cursor.
The Constraint Equation Browser now shows which sets that contain the equations are invoked.

This release of ez2view displays new data elements and so ez2update (our data feed software) now delivers this additional data. This change to ez2update allows customers who do not have their own InfoServer database to receive all the new data, and to display it using this latest release of ez2view. You can obtain the upgrade to ez2update from the ez2update downloads page

For customers who make use of their own InfoServer, you will need to ensure that ez2view has read access to all the new database tables that it needs – the list is in the ez2view Installation Instructions available above.

ez2view Version 4.1.192 - Released 9 November, 2011

This release provides a big improvement in the way that you can use ez2view to understand what is going on in the NEM. We have added a second screen that works like a browser to display all the details of Constraint Equations and Constraint Sets. This second screen lets you navigate between different sets and equations without disturbing your dashboard view, which stays on the first screen. You can now quickly navigate through all the constraint details to discover which constraints are having the most impact on the market, and how long they are likely to last.

In combination with the constraints browser, we have also enhanced our schematics displays to include icons that show the state of each unit within each station. These indicators tell you whether each unit is running, and whether the unit is on the left hand side of a bound constraint equation. We have also added indicators onto the interconnector icons to indicate whether or not the interconnector is in a bound constraint equation. This gives you an instant view into which units and interconnectors are being affected by bound constraint equations. To make this even more useful we have also added a menu of bound constraints to the schematics tabs so that you can visually isolate the stations and interconnectors that are being affected by individual bound constraints.

This version of ez2view also addresses several issues present in earlier releases.

EZTVA-408: Non-generating DUIDS are no longer displayed on the Schematics tab
The tool tips on the schematics tab previously listed a number of units whose names ended in "NL". While these unit names appear in data from AEMO they are not generating units and therefore have been removed from the tool tips.

EZTVA-405: ez2view does not connect to the Internet through a proxy where "Expect 100 Continue" is disabled
ez2view requires access to global-roam servers to operate correctly, and to do this ez2view usually needs to communicate through an organisation's proxy service. The Installation Instructions for ez2view describe how to set up your proxy to allow this communication. The problem in this case was that ez2view was not interacting correctly with older proxy services that do not support the "Expect: 100-Continue" header in the HTTP request. This has been fixed and ez2view now operates correctly with these older proxies. A similar fix will be required for ez2update, and this will be included in the next release.

EZTVA-392: The Constraint Set Gantt Chart incorrectly displays time information when in a non market timezone
The start and end of the chart, and the current time line were being incorrectly set if the timezone on the machine was a non-market timezone. This has been corrected and the GANT chart now displays correctly.

EZTVA-372: Intermittent crashes on Windows Vista and Windows 7
The application was crashing intermittently on Windows Vista or Windows 7 because an older logging component was attempting to write to the install directory (which these operating systems do not permit for security reasons). This has been resolved by ensuring that all logging is written to a common and correct place on all operating systems.

EZTVA-400: Filter expressions are incorrectly parsed in certain circumstances
Changing a Constraint Equation Filter for filters with complex logical expressions would occasionally cause the expression to be set incorrectly. This has been corrected.

EZTVA-410: Constraint Equations stay on the screen for longer than intended
Constraint Equation charts on the Constraints tab were staying on the screen for one dispatch interval after the equation was no longer invoked. The refresh mechanism for this screen has been modified and now displays only equations invoked in the current dispatch interval.

ez2view Version 4.1.174 - Released 12 October, 2011

This is a bug fix release that addresses the single problem below.

EZTVA-404: The SA tab in the Schematics plugin does not display the latest ElectraNet data for South Australia
The ElectraNet data that is displayed in the SA tab was not the latest data available to the application, although all other aspects of the ElectraNet data were displayed correctly. This issue arose because ElectraNet publish the data in local (South Australian) time, South Australia transitioned to daylight savings recently, and a bug in ez2view did not handle the transition correctly. This issue is now fixed and ez2view displays the latest data that it has for ElectraNet.

ez2view Version 4.1.173 - Released 09 September, 2011

Building on the Constraint Equation views introduced in the last release, this version of ez2view introduces a new display of Constraint Sets, and the schedule for invocation that the AEMO publish in the MMS table called GENCONSETINVOKE.

This enhancement allows you to better understand which constraints are coming along and to plan your responses accordingly. The display features:

A GANTT chart resource view, displaying Constraint Sets that are scheduled for invocation from 7 days ago to 90 days in the future.

The ability to drill into each Constraint Set to show detailed information about the set, including the Constraint Equations belonging to the set, a detailed view of the Constraint Sets' schedule and all properties of the Constraint Set.

The ability to filter the Constraint Sets to show only the ones relevant to you. A powerful filtering system allows you to form complex logical expressions so you can narrow down the range of Constraint Sets to only those that you are interested in.

This release also gives you even more control over the filters on the Constraint Equation displays by adding filters over the LHS terms. These LHS terms which are the ones that represent the network elements (such as units) that are affected by the constraint and are being controlled by the AEMO dispatch engine. You can now say things like “Show me all the constraint equations where my units are on the LHS” to find out which constraints affect one or more units. The MMS database uses Connection Point IDs for LHS terms, and ez2view allows you to filter constraint equations using these – but as well we have also included the ability for you to use DUID’s or Station IDs as shorthand for the Connection Points.

In addition, you can now also filter Constraint Equations based on the equations membership of a Constraint Set.

We have also updated the schematics view to add recently commissioned stations. The ones we have added are

Mortlake (Vic)
Oaklands Hill (Vic)
Gunning (NSW)
Woodlawn (NSW)
Bluff (SA)

This version of ez2view also addresses three issues from the previous release.

EZTVA-385: Problem with Estimated Trading Price query
The Estimated Trading Price for the current trading period (visible on the Display plugin) was calculated incorrectly when there was duplicate prices in any of the 6 five minute periods used in the calculation. This resulting in an incorrect average being displayed in some circumstances. This has been corrected to always use all 6 five minute periods in the calculation.

EZTVA-389: Timezone issue with Constraint Equation Effective Dates
The Constraint Equation details screen uses the Effective Data of the equation to load the appropriate data. In timezones other than NEM time (AEST) the Effective Date was being read incorrectly and therefore in some circumstances some Constraint Equation details may have been displayed incorrectly. This has been corrected.

EZTVA-390: ez2view will not display LHS terms if the data is incomplete
If there was missing meta information about a LHS term in the database, no LHS terms for a Constraint Equation would display. This has been corrected such that even if there is missing information, all LHS terms for a Constraint Equation will display correctly.

This version of ez2view has the following known issue, which will be resolved in a subsequent release.

EZTVA-392: The Gantt Chart displaying the Constraint Set schedule data does not correctly display its time information when in a non-NEM timezone
The Gantt chart that displays the Constraint Set scheduling information displays an incorrect current time (the red line), start date, and end date when the current timezone setting is not NEM time (AEST or GMT+10). The schedule and all visual indications of time other than the current, start and end are accurate.

ez2view Version 4.1.163 - Released 15 August, 2011

One of the most important aspects of the NEM is the application of Constraints by the NEMDE software - understanding which constraints are effecting the NEM is critical to understanding how the market is operating at any point in time. This release of ez2view adds screens that display, in real time, constraint equation data published by AEMO for every dispatch interval. The displays provide a unique and powerful view into the constraint data and include:

Charts of all Constraint Equations that are invoked in recent dispatch intervals, the current dispatch interval, and predispatch (both 5 minute and 30 minute).

The ability to filter Constraint Equations so that the screens show only those constraints that are most relevant to your business.

Drill-down into the details of each Constraint Equation so that you can instantly see all the critical parameters that help you understand the equation.

A dynamically sorted view of Constraint Equations which ensures that the most important Constraint Equations are visible to you when interesting things are happening in the NEM.

A static "watch list" display that always shows the Constraint Equations you are most interested in.

ez2view Version 4.0.114 - Released 4 May, 2011

In response to requests from many users, we have replaced the pie charts that were used to represent SCADA generation with trend charts that show the recent history for each station's generation. This enhancement allows you to better understand the context of the current SCADA generation figures. This feature supports configuration of the amount of history that is shown in the charts; the configuration parameters are in the file ez2viewAustralia.exe.config which is in the application install directory.

This version of ez2view also addresses two issues from the previous release.

EZTVA-353: The Date/Times displayed in the tooltips for the station/generator data are not in NEMTime when the timezone is not NEMTime.
All dates and times for station and unit generation data are now displayed in NEM time, not local time.

EZTVA-340 ez2view makes redundant calls to dataserver4 and dataserver3 to retrieve messages, reminders, and tips.
These redundant calls were slowing ez2view down in some circumstances and they have now been removed.

ez2view Version 4.0.92 - Released 10 February, 2011

For trial licenses of ez2view, access to AEMO and TNSP data is now provided to you via a web database hosted by us. Getting started with the trial is as simple as installing the ez2view application on a PC that has normal internet access.

For licensed copies of ez2view you still gain access to the AEMO data either by connecting ez2view to your existing InfoServer database (MMS Version 4.1.15 or higher), or you can obtain data from us via our ez2update data feed. If you license TNSP data from us you will need to obtain this data via our ez2update data feed.

ez2view Version 4.0.62 - Released 25 November, 2010

This version of ez2view introduces displays for the new dispatch time generation data that is published by AEMO under Change Notice 791. This new data is implemented by AEMO in MMS version 4.1.15 as part of the AEMO "End of Year 2010 Wholesale Electricity Market Systems’ (MMS) Software Release". This new version of ez2view will run successfully on the previous MMS version, but you will need to implement the InfoServer upgrade in order to receive the new data from AEMO.

This version of ez2view also addresses two issues reported by customers.

EZTVA-115: Queries are not optimized well for an Oracle based InfoServer.
We have optimized a number of queries and we recommend that customers using Oracle specifically test ez2view to ensure that performance is adequate.

EZTVA-52: Database settings were saved on a per-user basis.
The effect of this problem was that database connection strings needed to be configured for each user on a machine. These configuration settings are now saved on a per-machine basis and therefore need be set only once for that machine. On first execution of this upgrade on a machine:

if configuration settings exist for the current user, then the application will migrate these user settings to the machine level
if there are no configuration settings for the current user, the application will prompt for database connection strings and will save this new configuration at the machine level

This version of ez2view addresses all known issues from the pre-release version.

All configuration files for ez2view are now installed with the application rather than being downloaded from global-roam servers. This improves the reliability of the application.

ez2view is now provided in both MSI and EXE installers.
