Planning the Energy Management


Detailed planning

Specifications area

Various requirements can be selected for the energy system. Multiple requirements can be selected.

Requirement

Explanation

Optimizing self-consumption

You wish to obtain action recommendations for manual switching of loads in order to make optimal use of own PV energy on site (self-consumption).

Analysis of consumption and management of loads

You wish to obtain an analysis of your consumption. You also wish to have automatic intelligent switching of loads in order to make optimal use of own PV energy on site.

Energy management via the internet and visualization of PV system data

You wish to monitor the PV system via the Internet and visualize the PV system data in the Internet.

Online archiving

You wish to archive the PV system data in the Internet.

Remote diagnosis

You wish to analyze PV system faults via the Internet.

Visualization of PV system data on site

You wish to view the PV system data on site.

PV system maintenance and parameterization on site

You wish to enable maintenance and parameterization of the PV system on site.

Storage of PV system data on site

You wish to store the PV system data on site.

Connecting external sensors

You wish to connect sensors from third-party manufacturers to the PV system (e.g. anemometer, ambient temperature sensor).

Measuring global irradiation

You wish to measure the global irradiation.

Reading out energy meters

You wish to read out the data of the feed-in meter, the PV production meter and the purchased electricity meter.

Feed-in management

You wish to or need to participate in feed-in management with your PV system. In accordance with the Renewable Energy Sources Act (EEG) 2012, PV system operators with installed power of 30 kW to 100 kW must participate in feed-in management (variable active power limitation). PV system operators with installed power less than 30 kW have a choice: they can participate in feed-in management or they can limit the active power of their PV system to 70% (fixed active power limitation).

Control of large-scale PV power plants

You wish to control and regulate your large-scale PV power plant (connection to a SCADA system).

Wireless data transmission

You would like to wirelessly call-up the PV system data.

Notification in case of disturbances

You wish to be notified if disturbances occur in the PV system.

Various requirements can be selected for the PV system. Multiple requirements can be selected.

Requirement:

Explanation

Internet access is available

The PV system can be connected to the Internet.

Own operation control system is available

A control room (SCADA system) is available.

S0 meter interface is available

An S0 meter interface is available in the PV system.

D0 meter interface is available

A D0 meter interface is available in the PV system.

Procedure:

  1. Depending on your energy management requirements, enable the required checkboxes.
  2. Depending on the requirements that apply to your PV system, enable the required checkboxes.

Section: Design

In this section, you select the communication products for energy management. There are various procedures:

  • [Automatic design]: The communication products are automatically selected.

  • [Design alternatives]: From a list of suggestions with communication products, the required design alternative can be selected in the [Adopt design] column.

  • [Add communication product]: A communication product can be selected from the list of all communication products. If you have enabled the checkbox Only take current communication products into account, you can only select current communication products in the list.

Procedure:

  1. In order to only use current (not discontinued) communication products in the design, enable the checkbox Only take current communication products into account.
  2. You have the following options for selecting the communication products:
  3. To remove all added communication products from the section Result, click on [Delete system monitoring].

Section: Result

In this section, you obtain an overview of the internal and external communication products used in the project and the type of data transmission.

Procedure:

  1. If a communication product is to be included in the design alternatives, click on the lock icon next to the communication product. The lock icon is displayed closed.
  2. To undo the setting, click on the lock icon again.
  3. To delete a communication product, click on [X] next to the communication product.
