Released: 30th October 2015
Previous Version: 7.2
Next Version: 7.4

This version will automatically upgrade any previous Version 5-7 database. You may need to check the upgrade notes of earlier releases for any compatibility issues.

If you experience any problems during upgrade contact Energy Exemplar Support.

If your simulations run differently or slower in this version, also seek support and we will assist with the upgrade process.

Databases in 7.3 format will retro-grade to any previous Version 7.x however please check upgrade compatibility notes for all previous versions.

The following are the changes to existing functionality between this version and 7.3:

Setting the Competition Equilibrium Model to Cournot, will now run the Nash-Cournot algorithm on all phases except PASA. This behaviour can be controlled through the use of the following undocumented parameters:

LTPlan [CournotEnabled]
MTSchedule [CournotEnabled]
STSchedule [CournotEnabled]

By default the Nash-Cournot algorithm will formulate all regions into the model including "dummy" regions. These should ideally be removed from Cournot, as they can potentially cause issues. This can be done by explicitly setting the Region Is Strategic property to false.

A number of relatively minor changes have been made for the split run feature, which are important to note. These are:

Seeding - If splitting a model based on outage patterns or samples, and the model was seeded, then each split would use the same seed. This would result in the same variable values being calculated, meaning that the seed could not be set. Therefore there was no way to reproduce the split run result. This behaviour has now been changed and the seed from the model is used to seed all sub-split models. It is important to note that the results, from a "normal" simulation compared to a "split" simulation, will probably differ.

Planning horizon with look-ahead enabled - Previous versions of PLEXOS would simply disable the look-ahead, re-synchronize the chronological horizon and split the model. This behaviour has been modified and the "split by planning horizon" option is no longer available, if the look-ahead setting is enabled. However the "split by chronological horizon" option is available and does support splitting models which have the look-ahead settings enabled.

Solution naming - The combined/stitched solution names were previously output to folders in the following naming convention:

SplitExecution_20150814201028_Base - where the digits represent the date and time;

This has now been improved and the combined/stitched output folders and solutions will use the Model 'make unique option' to determine the naming convention of the solution.

The gas processing features that existed in the gas node have been separated out and put into the new Gas Plant class.

The Sulum solver is no longer supported and has now been removed from the software. Any Performance objects that have this solver enabled will either need to be removed or the solver setting updated. Failure to do so will result in the following warning:

 WARNING 3017: Performance.Sulum [SOLVER] defined with value 5 but must be In (0,1,2,3,4,6,7).

A number of optimizations have been made to the simulation engine and user interface codes, which will improve performance, especially in simulations that have a large number of steps/objects.

The following changes and/or new features specifically address performance of the simulation:

The Gurobi solver is updated to Version 6.0.3.0

Other engine performance improvements include:

PTDF calculation - better multi-threading support
Transmission network reduction - code refactoring and optimizations
Solution property calculation refactoring and code optimizations
Simulation memory improvements

Interface performance improvements include:

New charting component that utilizes low level GPU acceleration

By default LT Plan will only compute the global optimal solution in terms of the expansion and production decisions. However the new LT Plan Solution Count and Solution Quality attributes can be used to instruct the simulator to continue searching for the next "optimal" value. The sub-optimal results are written as text files, similar to the Write Expansion Plan Text Files setting.

The Gas Contract class has now been added. These objects link the quantity and price of a production agreement to the gas field via the Gas Field membership.

A "Regulation" reserve type has been added. A regulation service can be provided by the generator by either raising or lowering generation or pumped load.

A number of new features have been implemented to improve the solution viewer user experience. The major improvements are:

The overview control allows the user to quickly and efficiently zoom in/out and scroll through the selected data. By default overview window shows all data queried

Figure 1: Charting Overview Control

The charts by default display the legend in "compact" form. The legend settings can be modified using the following Chart ribbon check box options:

Figure 2: Chart Legend Options

The default compact legend places a small panel beneath the chart whose height is limited. This panel holds the legend information, and should the number of series become too large, then the panel becomes vertically scrollable.

Figure 3: Compact Legend

The floating legend places a floating window on the chart, which can be positioned anywhere within the chart control. This feature provides the user with more screen space (i.e. the fixed legend panel is not required) and also allows the user to toggle the series visibility on/off.

Figure 4: Floating Legend

The charts now offer more responsive and detailed tool tips, which can be toggled on or off as required.

Figure 5: Chart Tooltips

In addition to moving the overview window (or zoom bar), you can also change the time range by dragging the left and right hand X axis points. Similarly you are able to adjust the minimum and maximum Y value on both primary and secondary charts axis separately. This is done by clicking and dragging on each Y axis extreme points, which are indicated by small orange points.

Figure 6: Axis Adjustment

A new convergence chart type has been implemented and is available for any multi-sample series data. The following figure is an example of the convergence chart:

For more details on how to use the function in PLEXOS GUI, please refer to Convergence Chart.

Figure 7: Generation Series Statistics

The PLEXOS integrated Energy Model now brings together co-optimization for Electric, Gas and Water Models. The simulator provides these classes for the Water Model:

Class	Description
Water Plant	Water processing plant for processing raw water
Water Storage	Storage where water can be injected and extracted
Water Pipeline	Pipeline for transporting water
Water Node	Connection point in water network
Water Demand	Demand for water
Water Zone	Set of water nodes

The Water Model provides the capability to model the water supply chain starting with desalination through storage and transport to water demands. A secondary use is to apply the same model to water employment for generation and other water-intensive processes where co optimization with electric/gas/heat is required.

See the Water Modelling Guide for more information.

 Please note:
 A new license will be required in order to use these new Water classes.  Please contact your regional representatives for more information.
