2. About ASC 150 Storage About controller operation The ASC 150 Storage provides effective control for an energy storage system (ESS). You can add the controller to an existing plant, or use it with other DEIF controllers in a power/energy management system.

Application for an ASC controller in a power management system with AGC Genset and ASC Solar This is an example of an off-grid application, where the controllers are in a power management system together. The ASC 150 Storage controller controls the ESS, and the ESS breaker.
More information See the ASC 150 Storage data sheet for the variations on the grid-tied and off-grid arrangement. You can select the plant mode for the AGC Mains controller when you have a power management system. ASC Storage configuration Basic settings > Application type > Plant type > Plant mode...

Name Function Back Go to the previous page. The controller automatically starts and stops (and connects and disconnects) the storage system. The AUTO mode controller automatically controls the power to and from the storage system. No operator actions are needed. Silence horn Turns off an alarm horn (if configured) and enters the Alarm menu.
Controller functions 2.4.1 Grid-forming or grid-following Grid-forming Grid-forming is also called island, V/f mode, or off-grid. In grid-forming, the battery can act as the only energy source. The battery can provide the grid-forming power in island operation, and work together with non-grid-forming sources, like solar and wind. Island operation with PV ASC Storage Grid-following...
The ASC 150 Storage controller prioritises battery power over genset power. This means that the system uses as much battery power as possible before starting a genset. If the genset is in operation, the ASC 150 Storage controller tries to decrease the genset load to minimum (P DG minimum).
Power source operation: The ESS can be a power source if the SOC is above threshold 1. *Below threshold 1: The ESS can discharge as a power source until the SOC reaches the minimum. The ESS must then recharge to threshold 1 before it can discharge again.
3. Operating the system Mimic function Settings > Basic settings > Controller settings > Display > LED mimic Parameter no. Item Range Standard 6082 LED mimic Guided Standard The control buttons and LEDs are shown. If you the stop the energy storage system (ESS), the ESS symbols are shown in red.
3. Modbus commands NOTE * The controller has a limited number of digital inputs. See Digital inputs in the ASC 150 Storage Designer's handbook for availability. Commands in SEMI-AUTO mode Command Description Start The ESS start sequence is started Stop The ESS is stopped.
You can view and adjust a number of counters using the USW. Click the Σ icon in the upper horizontal menu to open the counters window. More information See General functions in the ASC 150 Storage Designer's handbook for more information about the functions in the utility software. 3.5.3 Trending Use the trending function in the utility software to see real-time operation.

How to configure trending 1. Click on Trending in the vertical menu on the left to see the trending page. 2. Click on Edit the trending tags 3. In the pop-up window, select the data you want to trend. 4. Click OK to confirm your selection. 5.
4. Modes of operation Operate the ASC in AUTO mode (remote) or SEMI-AUTO mode (local). In AUTO mode, the system closes the ESS breaker (if there is one) and starts ESS charging or discharging if the plant has a start signal. To keep it simple, the following examples show one ASC controller without power management.
2. The ESS starts and the ESS breaker closes. 3. The ESS supplies the load. More information See Automatic mains failure in the ASC 150 Storage Designer's handbook for the AMF parameters. OPERATOR'S MANUAL 4189341343A EN Page 18 of 36...
Fixed power In AUTO and SEMI-AUTO mode, the ESS supplies the amount of power configured in the set point for fixed power. The ASC can operate as a server to an external PLC/EMS controller. The ASC receives the fixed power set point from the PLC/EMS controller using, for example, Modbus or analogue signals.
Mains power export (MPE) In this mode a constant level of power through the mains breaker is maintained. The power can be exported to the mains or imported from the mains, but always at a constant level. The set point can be 0 kW. This is to make sure that the load is supplied from the ESS and that there is no import or export of power from the mains.

Peak shaving The ESS supplies the extra load when the mains import increases to more than the maximum import set point. When the load is less than the maximum import set point, the ESS recharges. You can enable the peak shaving charging limit with parameter 10724. When you have enabled this parameter, the ASC uses the peak shaving set point as the mains charging limit.

Communication with the battery management system (BMS) and power conversion system (PCS) If the ESS does not have a BCU, the ASC 150 Storage controller communicates with the BMS over Modbus. The ASC also communicates with the PCS over Modbus. This examples shows a simplified version of this type of communication.
