On the page consumption a consumption profile will be created, which is to be covered by the PV system.
A created profile can be copied to the clipboard in two different ways. A right click on the diagram opens a selection window in which you can copy the diagram either as an image or the monthly totals as raw data in table form.
The button opens a dialogue with two options:
In the dialog Define Consumption a wide variety of combinations of different electrical consumers can be combined to form a consumption profile. There are three ways to determine the consumption.
The consumption can be defined
Under the heading Measured consumers, electrical consumers can be defined using load profiles already imported. The database contains a large number of relevant load profiles (area 2). Area 3 shows more detailed information about the selected load profile. There, the energy consumption of the load profile can also be adapted to the actual energy consumption. The adjustment does not affect the original load profile. The options provided in area 1 allow you to import and delete new load profiles.
Procedure for importing new load profiles:
In the view consumer with load profile different load profiles can be loaded and individually adjusted. With the button new consumers can be created. A click on this button opens the dialog Generate new load profile. A consumer can be edited using the button . This option is only available for self-generated consumers.
To define an electrical consumer, proceed as follows:
In this dialogue, the energy requirements will be defined. A new individual appliance can be created using the button . A click opens the dialog New individual appliance. If the appliance is a self-generated record, it can be deleted via . An already defined individual appliance can be edited with the button .
To create an individual appliance proceed as follows:
Select one of four types. The following are available
Specify the Power and the Standby power of the device.
Define the operating time of the device. Hourly values are determined from the input variables.
In this dialog you define consumption profiles for the profitability model net metering.
If your net metering model shows an annual balance, enter the annual value of consumption, at monthly balance the monthly values.
The consumption profiles defined here should only be used for the profitability model Net-Metering, since only these profiles correctly represent hourly consumption. If you select Annual value, the consumption is identical for each hour of the year, for monthly values for each hour of the month.
If different tariff times are defined in the selected Net-Metering tariff, the Net-Metering tariff must first be selected on the page Economy because the consumption is entered separately for each tariff time.
In off-grid PV systems, load shedding allows the loads to be switched on and off depending on the battery charge status and time window. A start threshold and a stop threshold can be assigned for two time windows (time T1, time T2) for switching the load according to battery charge state (SOC = state of charge). When the start threshold is reached, the load is switched off and switched on again when the stop threshold is reached. You can use the time windows to display various day and night behaviors, for example. The entries are illustrated in the graphic.
