Network Editor

New Components

There are two options to define elements necessary to create the electrical system one-line (called schematic): User can either use the "Network" contextual ribbon tab from which the elements (of one or two poles) can be selected or use the most frequently used network component buttons in the Main tab of the ribbon.

From the "One Pole" Submenu user can select the Busbar, Generator and Load elements. The Busbar element can be entered with a custom number of pins (connection points) as required.

Figure 11. Network Elements from Network Contextual Ribbon Menu

From the "Two Poles" Submenu, the Line, 2-3 winding Transformer, UPFC and DC Line elements can be introduced to schematic.

Figure 12. DeepEdit Main ribbon: Network Elements group

	Insert new Generator element.
	Insert new 2-winding Transformer element.
	Insert new Load (withdraw point) element.
	Insert new Busbar element.
	Insert new Transmission Line element.
	Insert new breakpoint in Transmission Line elements.
	Insert new text label.

Every time user inserts elements to the schematic, they’ll always appear in the upper left corner of the Deep-Editor main window. This applies to any editor: network, market or hydrology,

Figure 13. Network element inserting using toolbar buttons

The size of the displayed object may vary depending on the zoom level that is selected at that moment. The inserted new element can be moved anywhere over the schematic. To do this, user must click on the new element and move the mouse without releasing the button to the desired position. If necessary, the user can use the horizontal or vertical scrollbars to move around the schematic.

Elements such as generators and loads must be connected to a busbar. To connect busbars between them, the line element or the transformer element is used.

Figure 14. Insert a Network elements from the DeepEdit Main Ribbon Menu

To insert a new transmission line, user must first switch to line drawing mode by clicking on the corresponding button. Once in this mode, to insert the line you must indicate the pin of the initial busbar where the line begins, holding down the left mouse button, indicate the pin of the final busbar where the line ends and release the mouse button.

The line is an element that is drawn straight from the final bar to the initial bar. You can make breaks in the line if required, for this you can insert nodes to the line, as many breaks as you need to do to the representation of the line.

To insert a breakpoint (also called node), user must click on the breakpoint insert button. Then click on the line in the position where you want to create the breakpoint. To be able to move existing breakpoint to a different position, user must select the node in the element selection mode and move it keeping the left mouse button pressed.

Figure 15. Inserting a node into a line in the DeepEdit Network Editor

To insert text label in the schematic, user must press the text insertion button, then a window appears that allows you to write the text to enter the diagram as shown in the figure.

Editing Components

There are three ways to display the element properties window. User can select the element to modify with a single mouse click, and then select the Edit Component function in the Edit menu.

Figure 17. Edit Component Menu option

Alternatively, user can press the keyboard keys shortcut ctrl. + E to show the selected schematic.

The easiest way to access the properties window of the element is to double click with the left mouse button on it.

The properties window allows user to enter component’s Name, Operation Information and Economic information and others.

Double-clicking a busbar, Busbar modification window should pop up. In this frame, user can enter the name (NAME) with which the program should identify the bar. The user can enter an alternative name for identifying the same busbar (ALIAS).

Figure 18. Operation Information in the Busbar Properties window

• Nominal Voltage: Nominal voltage in kV.

• Number of fields: Number of pairs of pins

• Umin: Lower voltage limit in p.u.

• Umax: Upper voltage limit in p.u.

• "In Service?" Checkbox: Availability (for all calculations for all periods).

In the upper right sub-menu, you can choose to enter the economic information of the bar.

Figure 19. Economic Information in the Busbar Properties window

Generator

Double clicking a generator element, the Generator properties window should pop up. User enter the name with which the generator will be identified in the simulation, as well as an alias or alternative name. It has a menu that allows user to select the type of information to be displayed, whether it is for economic operation, locational or operational information.

Figure 20. Operational Information in the Generator Properties window

The figure shows the operation information of a generator. You can indicate the nominal voltage with which that generator will work through a submenu that allows you to choose between 0 and 750 kV.

• Output limit: Maximum apparent power that can be obtained from the generator.

• Pmin: Minimum active power generation

• Pmax: Maximum active power generation

• Qmin: Minimum reactive power generation

• Qmax Maximum reactive power generation

• P (Soll) Active power generation, optimal dispatch solution

• Q (Soll) Reactive power generation, optimal dispatch solution

• If_Type Select the type of generator, PQ, PV or Slack

In case user wants to simulate an economic dispatch, it is required to define the economic information of the generator.

Figure 21. Economic Information in the Generator Properties window

User can enter the parameters alpha, beta and gamma which defines the operating cost model of the generator. User can enter the entry date (into operation of the generator) as well as its decommissioning date. It can be indicated if the generator is thermal, hydraulic reservoir, hydraulic run-of-river, nuclear or other other.

Line

User can double-click on the line element to display the line properties window or using the "edit component" command from the "Edit" menu. User can also use the keyboard shortcut by pressing the Ctrl + E keys.

Figure 22. Operational Information in the Transmission Line Properties window

Users can edit parameters the transmission "line" component using this window. User can introduce the name of the component as well as entering an alias for it. User can modify the nominal voltage, the transfer capacity, the resistance, and reactance parameters. The latter can enter them in units of Ohm / km or in [p.u]. User can also edit line’s total length.

Similarly to "generator" component, the "line" component has the option to define entry and exit dates

Figure 23. Economic Information in the Transmission Line Properties window

In the economic information section, the user can enter the investment cost (VI or VNR), and the cost operational and maintenance cost (FOM or COYM or COMA).

Trafo (Transformer)

Double-clicking on a transformer component should pop up the properties window. Information includes operating, economic and graphical (and locational) information.

Figure 24. Operational Information in the Transformer Properties window

User can define the following information in the Transformer’s properties window:

• Nominal voltage P: Nominal voltage of the primary in kV

• Nominal voltage S: Nominal voltage of the secondary in kV

• Pcu: Losses due to winding resistance in kW

• Pfe: Losses in the transformer’s core in kW

• Uk: own-base series impedance

• I₀: own-base magnetization Impedance

• Smax: Maximum Transformer’s capacity in MVA

• Sn: Rated power in MVA

The values of pcu, uk, and I₀ can be calculated by the DeepEdit when user enters the parameters of the resistance and the reactance in p.u. of the PI model of the transformer. These parameters can be entered in the Operation Information section (Parameters in (p.u.)) as shown in the figure.

Figure 25. Parameters in pu in the Transformer Properties window

The values of pcu, uk, and I₀ will only be calculated if the parameter ur1 is equal to the nominal voltage of the primary and ur2 is equal to the nominal voltage of the secondary, and if only the model has capacitive components in parallel. The calculations made by the DeepEdit using the π-model are as follows:

• Sn: Nominal Power of Trasformer [MVA] 0≤Sn≤Smax

• Sref: System reference Power [MVA] (typically 100). System reference power can be entered by selecting the Schematic options in the Analysis Tools menu.

• X: π-model reactance in pu.

• R: π- model resistance in pu.

NOTE: The values of Sn must be entered for the calculation of pcu and uk, and they both need to be greater than 0 and less than or equal to Smax. This will be alerted by the properties window, preventing it from closing if conditions are not met.

Figure 26. Economic Information in the Transformer Properties window

The economic information is as follows:

• Life Time: Years in which the transformer depreciates

• Entry Year

• Entry Month

• Exit Year

• Exit Month

• Investment cost Investment cost of the Transformer (VNR) in UD Dollars

• COYM Cost of operation and annual maintenance of the Transformer in dollars

In the graphic information section of the transformer, Users can modify the orientation (horizontal or vertical) in which DeepEdit shows the transformer.

Figure 27. Graphic Information in the Transformer Properties window

The four possible drawing positions of Transformers are:

Transformer parameters calculation

Assume that the following values are defined for a transformer:

• Uk = 11.5266% short-circuit test voltage as a percentage of the nominal voltage according to the manufacturer,

• Pcu = 292.5 kW copper losses associated with the short circuit test,

• I0 = 2% No-load current test as a percentage of the rated current,

• Sn = 75 MVA Nominal apparent power of the transformer,

• Ur1 = 220 kV Nominal voltage according to manufacturer on the primary side,

• Ur2 = 110 kV Nominal voltage according to manufacturer on the secondary side,

• Un1 = 220 kV Nominal voltage of the system on the primary side,

• Un2 = 110 kV Nominal voltage of the system on the secondary side,

• Sb = 100 MVA Base power of the system.

Thus, the values in per unit (on a common basis) will be given by:

For the parameters given above:

• rcc = 0.0052 pu

• Zcc = 0,1537 pu

• xcc = 0,1536 pu

• bm = 0.01 pu

Load (Consumption Point)

Double clicking on a load or consumption should display the Load properties window. User can enter the operational and the economic information corresponding to that load.

Figure 29. Operational Information in the Load Properties window

• Nominal Voltage: Nominal voltage of load operation

• Initial Load P: Initial value of the real power consumed by the load (at the entry date)

• Initial Load Q: Initial value of the reactive power consumed by the load (at the entry date)

• Growth Rate: Percentage of annual growth of the value of the load

• Pmin: Percentage of the initial power value corresponding to the minimum power that the load can consume (for LDC creation).

• Pmax: Percentage of the initial power value corresponding to the peak load

• In Service?: Checkbox that indicates whether or not to include this load in the simulation calculations.

The “Show LDC” button activates a window that shows the simulated load duration curve. The curve shows the consumption in MW per hour of the year. The order is not chronological, it is ordered from higher consumption to lower consumption according to the input data of Pmax and Pmin.

Figure 30. Load duration curve window

The economic properties of the load can be accessed by selecting the Economic Information section.

Figure 31. Economic Information in the Load Properties window

In this section the user can enter the beta and gamma parameters of the economic model of Loads. User can enter the entry and exit date as well. The investment cost can also be defined.

Note: If you are going to load the dispatches from the database (TPDB), it is suggested that the period in which the load is going to be active is the entire simulation period. In this way, it prevents throwing missing loads execution errors (more loads in the database than the number of loads schematic for the given dates).
