What is the DC-Link?

> The DC-Link is the direct current intermediate circuit in a battery storage system (BESS), which transmits energy between the inverter and the battery modules. It serves as galvanic isolation and a buffer to stabilise the system voltage according to IEC 62477. A stable DC-Link voltage is essential for the efficient efficiency of the converter and the service life of the cells.

Bound to the register

dc_bus_v This Wizard is linked to a real register. The value is read as read-only and calculated in-house — nothing leaves the plant. The value runs inside the container.

What the AI reads in this component

What the AI reads
  • Deviations from nominal voltage as an indicator of cell imbalances
  • Monitoring of voltage peaks to prevent component overheating
  • Determination of the degree of loss in the inverter by comparison with the battery voltage
  • Identification of power limits via overcharge protection algorithms
Scenario

Monitored: continuous

The scenario: > Monitored: continuous · Grid Point & PCS The scenario: an unchecked peak defines the annual maximum value, resulting in a higher power price for twelve months. The AI: detects the rising edge early and discharges against it — the peak does not occur. It identifies the trend before the limit is reached.

Why it is important

A stable DC-Link voltage minimises thermal losses and prevents premature degradation of the battery cells, directly increasing the cycle life. Through precise monitoring of the register dc_bus_v, unwanted switching cycles can be avoided. This optimises the Round-Trip Efficiency and secures the long-term profitability of the plant. avoided peak (kW) · power price (€/kW·a) → — €/year Calculation path: avoided peak × power price
