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 30. 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.

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

Figure 32. 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).
