Plot

Introduction

The Plot Node analyses data from connected Nodes and outputs results to other connected Nodes or outputs plots in a graphical format.

This Node is typically used for the following:

• Outputting dynamic study results (e.g. plotting the time-series response of voltage at a bus).
• Benchmarking two or more power system models against each other.
• Analysing data (e.g. calculating settling time on a generator's reactive power output).
• Outputting scatter plots summarising analysed data (e.g. plotting a droop curve based on results from multiple dynamic studies).

User inputs

Define plot

Output file name

Defines the output directory and file name of the plot, excluding the file extension.

Example:

DMAT_Table_1

danger

Each Plot Node represents a single output file. Output file names within a simulation must be unique.

As a result, Loop Variables and Internode Variables are not supported in the Output file name field.

Output file types

Defines the output file types. Currently, the Plot Node supports:

• [Mandatory] Portable Document Format (PDF)
• [Optional] Interactive Visualisation (HTML)

Plot title

Defines the title of the plot.

Example:

Sunny Solar Farm

Plot subtitle

Defines the subtitle of the plot.

Example:

S5.2.5.4 - Frequency ramp to 52 Hz, 4 Hz/sec, minimum system strength

Define subplots

Type

Defines the type of plot to generate. Options:

• Time series: Plot one or more sub-plots with a common horizontal (x) axis with time as the independent variable. All sub-plots share a common x-axis range. This is typically used for displaying time series data from dynamic studies.
• Scatter plot: Generic scatter plot of channels on an x-axis and y-axis. This is typically used for post-processing and analysis of simulation data.

x-axis: Channels

Defines the channel to be used as input data for plot's x-axis. Channels are defined using Internode Variables from a connected Node. Multiple channels are supported and are entered on subsequent lines.

Example: Display the Q(V) droop curve generated by a connected Table Node (with data from a connected PSS®E Dynamic Node) with the following Data: voltage={{i_vpoc}} and reactive_power={{i_qpoc}}:

x-axis: Channels

{{voltage}}

note

Internode Variables names don't need to be unique with a Run. If a Plot Node channel is defined as {{voltage}} and a Table Node has data from two connected Nodes (e.g. PSS®E Dynamic Node and a PSCAD™ Node) output Internode Variables with the same name of voltage, the Plot Node will plot both channels on the same scatter plot.

x-axis: Label

Defines horizontal axis label of the plot.

Example:

x-axis: Label

V [p.u.]

x-axis: Scaling

Defines the scaling of the horizontal. Options:

• Auto: Automatically scales the axis with reasonable whitespace for simplified analysis.
• Auto: Tight: Automatically scales the axis as far as possible.
• Manual: Fixed user-defined minimum and maximum values.

x-axis: Min

Defines the minimum displayed value on the horizontal axis. Only appears if x-axis: Scaling is set as Manual.

Example: Set the minimum value for the horizontal axis to 0.

y-axis: Min

0

x-axis: Max

Defines the maximum displayed value on the horizontal axis. Only appears if x-axis: Scaling is set as Manual.

Example: Set the maximum value for the horizontal axis to 100.

x-axis: Max

100

Subplot configuration space

Each plot may contain up to a maximum of 3 pages, each with 16 subplots. The grid displayed represents the layout of the subplots on a single page. Use the pages, rows and columns dropdowns to change this layout as desired. Click on the '+' icon to add a subplot, and click on the 'Configure' button to configure the subplot. Subplots can also be dragged to their preferred location on the page.

Subplot title

Defines the title of the subplot.

Example:

P POC

Enable subplot legends (Time Series only)

Enable or disable the display of legends on the subplot. Legend names are defined using the LEGEND Argument in OUTPUT Commands (e.g. PSS®E Dynamic Node - OUTPUT Command). Options:

• Checked: Legend will appear on the subplot.
• Not checked: Legend will not appear on the subplot.

Enable straight lines with scatter plot (Scatter Plot only)

Enable or disable straight lines connecting the scatter plot data. Options:

• Checked: Scatter plot will include straight lines.
• Not checked: Scatter plot will not include straight lines.

info

You can configure channels on the left and right y-axes separately. Commands are only currently supported on left y-axis channels.

y-axis: Channels

Defines the channels which are used as input data for the subplot. Channels are defined using Internode Variables from a connected Node. Multiple channels are supported and are entered on subsequent lines.

Example: Display the time series data generated by a connected PSS®E Dynamic Node with the following Commands in its output field: OUTPUT, LINE=100->200#1, VAL=P, NAME=i_terminal_p and OUTPUT, LINE=400->500#1, VAL=P, NAME=i_poc_p.

{{i_terminal_p}}
{{i_poc_p}}

note

Internode Variables names don't need to be unique with a Run. If a Plot Node channel is defined as {{i_poc_p}} and two connected Nodes (e.g. PSS®E Dynamic Node and a PSCAD™ Node) output Internode Variables with the same name of P_POC, the Plot Node will plot both channels on the same subplot.

y-axis: Label

Defines vertical axis label of the subplot.

Example:

V POC

y-axis: Scaling

Defines the vertical axis scaling of the subplot. Options:

• Auto: Automatically scales the vertical axis based on the channel type with reasonable whitespace for simplified analysis.
• Auto: Tight: Automatically scale the vertical axis as far as possible.
• Manual: Fixed user-defined minimum and maximum values.

y-axis: Min

Defines the minimum displayed value on the vertical axis of the subplot. Only appears if y-axis: Scaling is set as Manual.

Example: Set the minimum value for the sub-plot vertical axis to 20.

20

y-axis: Max

Defines the maximum displayed value on the vertical axis of the subplot. Only appears if y-axis: Scaling is set as Manual.

Example: Set the maximum value for the sub-plot vertical axis to 30.

30

• TAT (float)[Optional][Multiple]: Time of the start of a transient, where different error band calculation methodology may be required. Defaults to no transients. Multiple Arguments supported.
• DISPLAY (str)[Optional]: Display the calculated percentage of the samples which appear within the error band bounds on the subplot. Defaults to DISPLAY=YES. Options:
  • DISPLAY=YES: Percentage will be displayed on the subplot.
  • DISPLAY=NO: Percentage will not be displayed on the subplot.
• NAME (str)[Optional]: Outputs the percentage of the samples which appear within the error band transient window bounds to an Internode Variable. Output names must be unique within a Node.

note

The reference channel for the error bands is chosen using the following logic:

• The left most Data Node connected to the Plot Node is used as the reference for the error bands.
• If no Data Nodes are connected to the Plot Node, the left most PSCAD™ Node is used as the reference for the error bands.
• If no PSCAD™ Nodes are connected to the Plot Node, the left most PSS®E Dynamic Node is used as the reference for the error bands.

info

Currently, ADVBANDS only supports error bands derived in accordance with Section 6 of AEMO's Power System Modelling Guidelines (PSMG) [AEMO | July 2018]. The following methodology is applied:

• The start of the 'Transient Window' is defined by the user using TAT=.
• The end of the 'Transient Window' is automatically calculated based on when the channel settles to within ±5% of the maximum induced or reference quantity change [Source: Section 6.2 of PSMG].
• Within a Transient Window, the upper and lower error bands are the least restrictive of:
  1. The channel +10% of the maximum induced or reference quantity change [Source: Section 6.2.1(b)(i)(A)].
  2. The channel -10% of the maximum induced or reference quantity change [Source: Section 6.2.1(b)(i)(A)].
  3. The channel shifted to the left by 20 milliseconds [Source: Section 6.2.1(b)(i)(B)].
  4. The channel shifted to the right by 20 milliseconds [Source: Section 6.2.1(b)(i)(B)].
  5. The channel +2% of the BASE= value provided [Source: Section 6.2.1(d)(i)].
  6. The channel -2% of the BASE= value provided [Source: Section 6.2.1(d)(i)].
• Outside of a Transient Window, the error bands are bound by:
  1. Upper bound is +2% of the BASE= value provided [Source: Section 6.2.1(d)(i)].
  2. Lower bound is -2% of the BASE= value provided [Source: Section 6.2.1(d)(i)].

The BASE= values should be chosen using the following logic:

• If the channel is active power, then BASE= should be your project's registered capacity [MW].
• If the channel is reactive power, then BASE= should be your project's maximum reactive power [MVAr].
• If the channel is voltage, then BASE= should be 1.

Example: Display error bands compliant with AEMO's Power System Modelling Guidelines on the reactive power subplot. Use a base of 40 MVAr. The channel should have two Transient Windows starting at 10 seconds and 20 seconds.

ADVBANDS, BASE=40, TAT=10, TAT=20
