Third-party Storage Control

In brief​

Making storage installations controllable for third parties in order to increase the system's yield based on external information.

The third-party storage control strategy is applied when a storage installation is present behind a connection and the (end) customer wishes to control this installation based on external information. This strategy is often used when a customer has entered into an imbalance energy contract and therefore wants their storage system to be controlled by, for example, a BSP or CSP. The third-party storage control strategy, in combination with the Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. energy controller, facilitates control by the energy supplier.

What are BSP and CSP?

BSP stands for Balance Service Provider and CSP stands for Congestion Service Provider. These are parties that are certified and approved for providing imbalance services or capacity management, such as for a capacity-limiting contract (CBC).

How it works​

This strategy connects the trading algorithm of the energy supplier (also known as the 'trader') with the storage system or battery on site. The Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. energy controller is physically connected to the battery, and via an API connection the trader can then control the installation as desired. The strategy monitors the correct processing of the control signals.

Local monitoring of the grid connection​

The Third-party Storage Control strategy is often combined with the Grid Guard. This strategy ensures that, in parallel with the control signals from the connected trader, the Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. locally monitors the limits of the grid connection and ensures that they are not exceeded. This guarantees that the battery system can always be charged or discharged safely and to its maximum capacity.

Additional information​

The Third-party Storage Control strategy makes it possible to control battery systems based on external market signals. The text below explains in more detail how this strategy operates in combination with other systems and which technical and operational considerations apply.

Different controlling parties​

The chosen controlling party (for example a BSP or CSP) can vary greatly when it comes to external control. Each party uses its own (trading) algorithm. The Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. supports switching between parties without additional configuration costs. This keeps the installation flexibly deployable with different energy suppliers or market parties. Some of the parties that already have a connection include:

  • Repowered
  • Edmij
  • Eneco
  • Groendus
  • Greenchoice
  • FridayEnergy
  • EddyGrid
  • PureEnergie
  • Tibo Energy

Connection and validation​

For the connection with the trader, the Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. uses a secured API connection. This connection is tested in advance according to established process agreements between Envitron and the connected trading platforms. After successful validation, the strategy is released for operational use via the service partner or the end customer.

Combination with a power control strategy​

When the battery system is controlled by an external party, the power demand on the connection can vary greatly. A Grid Guard prevents the maximum connection capacity from being exceeded during these control operations. Combining the Third-party Storage Control strategy with the Grid Guard is therefore recommended in situations where an installation is subject to a limitation on the grid connection that needs to be safeguarded locally.

Integration with an existing power control strategy​

If a power-limiting strategy is already active on the generation installation, this will be taken over by the Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. — in many cases without the need to install additional hardware. This prevents conflicts between external signals and local power limits. When multiple strategies operate independently of each other, this can lead to instability ("hunting") or error messages in the installation. It is therefore necessary for the existing power control strategy to be integrated into the Envi.Baseenvi.base De energiecontroller van Envitron die apparaten uitleest, aanstuurt en data opslaat achter de hoofdaansluiting. and removed from the original installation configuration. This is fully handled during installation.
