ReFlex is a software solution that empowers aggregators to create a powerful Virtual Power Plant. This VPP can utilize the flexibility of large quantities of (small) devices effectively for multiple purposes. Enabling the flexibility of DER assets, such as: electric cars, batteries and solar panels, to be utilized in both energy markets and ancillary services markets. In this way the value of flexibility can be stacked. Because ReFlex is compatible with multiple open smart grid standards such as: EFI, USEF and OCPI, it is easy to deploy in the operational process of an aggregator. ReFlex consists of the following three concepts.
About ReFlexThe beating heart of ReFlex is its Flexibility Engine. The Flexibility Engine is a highly complex mathematic module that is able to provide detailed insight into the available flexibility in a cluster of connected DERs. Secondly, it provides insight into the consequence of dispatch choices, such as ‘how much flexibility is left in the portfolio after a (hypothetical) dispatch? With this functionality an aggregator gets grip on the available flexibility in its cluster and can utilize it with the highest impact.
The application of open communication standards is a key feature of ReFlex. DERs can easily be connected and controlled because ReFlex is compatible with the Energy Flexibility Interface (EFI) protocol, an initiative of the Flexible Power Alliance Network. ReFlex is ready for congestion management through the use of flexibility at distribution grid level by being compatible with USEF.
An Aggregator has a commercial role in the energy system and to be competitive, it needs to develop smart trade strategies to utilize the flexibility in its portfolio. These trade strategies form the identity of the Aggregator. To facilitate this, ReFlex supports configurable trade strategies (business rules), with which the Aggregator is always in full control of the flexibility in its portfolio. ReFlex is a flexibility aggregation platform which is the perfect aggregation tool for parties that want to use flexibility commercially for multi-purpose and therefore need fine grained insights into the available flexibility in their portfolio.
TNO connects people and knowledge to create innovations that boost the competitive strength of industry and the well-being of society in a sustainable way.
