Commissioning Using Deployment Wizard (V300R023C00)

Context

The deployment wizard allows you to set basic SmartLogger parameters, connect Huawei devices, power meters, and EMIs, configure battery control, Huawei NMS, and third-party NMS, and implement interworking with third-party devices. In utility-scale storage-only scenarios and microgrid scenarios, the insulation fault detection function of the Smart PCS is added to improve system safety and reduce costs.

After the SmartModule communicates with the SmartLogger properly, the SmartLogger automatically identifies the SmartModule. The device name of the SmartModule is Module(M1), and the corresponding port is M1.port.

Prerequisites

In utility-scale storage-only scenarios and microgrid scenarios, the insulation fault detection function of the Smart PCS supports only the following Huawei devices.

     Figure 6-22 Working mode
     
     Table 6-5 Battery control working modes

     Working Mode	Mode Description
     No control	The SmartLogger directly delivers the external scheduling power limit. No other power scheduling control is performed. The power is automatically controlled by the device.
     Maximum self-consumption	This mode applies to areas where the electricity price is high, or areas where the FIT subsidy is low or unavailable. The PV+ESS system generates sufficient PV power for loads and uses the surplus PV power to charge the ESS (if the PV power is insufficient for loads, the TOU mode is recommended). PV power is preferentially supplied to loads, and the surplus power is used to charge the ESS. If the ESS is fully charged or is being charged at full power, the surplus power is fed to the grid. When PV power is insufficient or no PV power can be generated at night, the ESS discharges power to loads. This improves the self-consumption rate and energy self-sufficiency rate, and reduces electricity costs. The grid cannot charge the ESS but can supply power to loads. The SmartLogger performs ESS scheduling based on the external scheduling power limit and the preceding policies.
     Fully fed to grid	This parameter applies only to distributed scenarios. This mode maximizes the PV energy fed to the grid. When the PV output power in the daytime is greater than the maximum output capacity of the inverter, the surplus PV power is used to charge the ESS. When the PV output power is less than the maximum output capacity of the inverter, the ESS discharges energy to the inverter to maximize the energy fed from the inverter to the grid. The grid cannot charge the ESS. The SmartLogger directly delivers the external scheduling power limit. NOTE: If the CMU is connected, the Fully fed to grid working mode is not displayed.
     TOU	It is applicable to the PV+ESS system and ESS-only system where peak to valley electricity prices are different and power meters are available. You can manually set the charge and discharge time segments. For example, if you set the low electricity price period at night as the charge time, the system charges the batteries at the maximum power during the charge time. If you set the high electricity price period as the discharge time, batteries can discharge only during the discharge time based on the actual load power, reducing electricity costs. Click Add to set the charge and discharge time segments. A maximum of 14 time segments can be set. During the charge time, the grid can charge the batteries. During the discharge time, the batteries can supply power to the loads. In other time segments, the batteries do not discharge. The PV system and grid supply power to loads, and the PV system can charge the batteries. In some countries, the grid is not allowed to charge batteries. In such case, this mode cannot be used. The SmartLogger performs battery scheduling based on the external scheduling power limit and the preceding policies.
     TOU (fixed power)[1]	It is applicable to the PV+ESS system and ESS-only system where peak to valley electricity prices are different and power meters are unavailable. You can manually set the charge and discharge time segments. For example, if you set the low electricity price period at night as the charge time, the system charges the batteries at the fixed power during the charge time. If you set the high electricity price period as the discharge time, batteries can discharge only during the discharge time at the fixed power, reducing electricity costs. Click Add to set the charge and discharge time segments. A maximum of 14 time segments can be set. During the charge time, the grid can charge the batteries. During the discharge time, the batteries can supply power to the loads. In other time segments, the batteries do not discharge and are not charged. In some countries, the grid is not allowed to charge batteries. In such case, this mode cannot be used. The SmartLogger performs battery scheduling based on the external scheduling power limit and the preceding policies.
     Charge/Discharge based on grid dispatch	This mode applies to utility-scale plant scheduling scenarios where a third-party controller delivers active power scheduling commands. The purpose of scheduled discharge is to meet the active power scheduling target value at the grid access point. PV energy is preferred. If the generated PV energy is insufficient, the batteries discharge and the energy is fed to the grid based on the active power scheduling target value. If the generated PV energy is sufficient, the energy is fed to the grid based on the active power scheduling target value, and the surplus PV energy is used to charge the batteries. The purpose of scheduled charge is to meet the active power scheduling target value at the grid access point. If the battery charge power is insufficient or the Smart PCS limits the power, the grid charges the batteries with the maximum capability. If the batteries are not fully charged when the scheduling target value is met, the PV power is used to charge the batteries.
     Custom[2]	This mode applies to utility-scale plant (with ESSs) scheduling scenarios. Customers can control the battery discharge power. Non-discharge period: The batteries cannot discharge and can be charged based on the scheduling command. Discharge period: If Adaptive discharge power is enabled, the control logic is the same as that for scheduled charge and discharge. The battery charge and discharge power is determined by the upper-layer scheduling command. If Adaptive discharge power is disabled, the battery discharge power is fixed to the reference value set by the customer. In this case, the upper-layer scheduling command controls only the PV inverters but not the batteries.
     Note [1]: You can set this parameter in SmartLogger V300R023C00SPC150 and later versions. Note [2]: You can set this parameter in SmartLogger V300R023C00SPC120 and later versions.

     TOU	Preferred use of surplus PV power	Charge: When the PV power is greater than the load power, the surplus PV energy is used to charge the batteries. After the maximum charge power is reached or the batteries are fully charged, the surplus PV energy is fed to the grid. Fed to grid: When the PV power is greater than the load power, the surplus PV energy is preferentially fed to the grid.

This setting is applicable to the scenario where the FIT is higher than the electricity price. The grid cannot charge the batteries.

   • Set the automatic calibration functions.

     Parameter	Description
     Automatic SOC calibration	If this parameter is set to Enable, automatic charge and discharge calibration is allowed for battery racks.

If the battery SOC stays in the range of 40% to 60% most of the time, for example, in the frequency regulation scenario, the recommended online calibration interval is less than or equal to 30 days. If the battery SOC stays below 10% or at 100% most of the time, for example, in the peak shaving scenario, the recommended online calibration interval is less than or equal to 180 days.
     Automatic SOH calibration	If this parameter is set to Enable, the ESS automatically calibrates the SOH precision and fully charges and discharges each battery rack in turn. If this parameter is set to Disable, automatic SOH calibration is not allowed for battery racks.
