|---|
| Scope | The description of prequalification of resources (DER) to participate in the flexibility market represented by Flexibility Platform (FP) |
| Objective(s) | To register DER in the Flexibility Register (FR), which will enable the submission of bids on FP and participation in the flexibility market |
| Related business case(s) | Prerequisite for other BUC |
1.4. Narrative of Use Case
Short description
The use case describes the prequalification process of DERs introduced by Flexibility Service Provider (FSP) to be registered in Flexibility Register. This registration is the prerequisite to participate in flexibility market processes on FP.
The DER can be based on generation resources, energy storage and consumption (households, SMEs and industrial enterprises). The FSP can own one or more DERs or can be an aggregator which aggregates several DERs in its portfolio (called as FSPA)
Complete description
Scenario 1 –FSP prequalification:
• Market prequalification
Description: FSP registers itself on FP as natural or legal person In details it contains:
o The statement of legal and financial status
o The confirmation of access to FP (rules, RODO confirmation etc.)
o The declaration of the entire volume
The status of FSP (pending) is registered in FR
• Certification of DER
Description:
Declaration of DER or DERs
FSP declares its flexibility potential ready to provide services. In details it contains:
o The declaration of DERs and their technical characteristics
o The statement of connection point for each DER (PoC), its location and metering data availability
The status (pending) of FSP and DERs are registered in FR
• SO to which DER is connected confirms the right status of DER, its connection, location and availability of metering data. It is done for each DER declared by FSP.
SO confirms location for each DER by assigning it to the TSO-DSO coupling point. In the case of incorrect assignment, SO makes an appropriate correction.
The status (pending) of each DER associated with FSP is reported in FR.
• Product prequalification
Description:
Based on the list of available products published by FP, FSP decides on the bases of which products it is going to provide flexibility services.
• FP checks whether the characteristic of DER fits with the characteristic of the chosen product.
FP executes the automatic comparison of both characteristics: the products and DER or DERs managed by FSP. In case of positive checking, FP registers the DER or DERs allocated to the FSP in FR as qualified for the product in question. In case of mismatch, the message is sent to FSP and request for prequalification is rejected.
It is done for each selected products.
• FP requires from FSP additional actions and confirmation in case of balancing products.
There are additional requirements and procedures related to balancing products, in particular FSP should operate in the balancing market through a balancing service provider (BSP) or obtain this status itself.
For specific products some tests confirming compliance with the requirements may be required.
When the FSP fulfils these requirements, the result is reflected in the FR, confirming a positive product prequalification.
• Static grid prequalification
Description:
FP, in the grid prequalification process, initiates the process asking all impacted SOs to check if the activation of DER under consideration can be accepted i.e. does not violate grid security limits. The responsible SO assesses and decides the outcome of the grid prequalification process. If no, and DER is not divisible, the DER is rejected and message regarding DER rejection in the grid prequalification process is sent to the FSP. If no, and DER is divisible, the FP reduces the capacity to the limit set by SO and informs (sends the message to) the FSP that the DER is registered in FR, but with the capacity limit. If yes, the status of DER (qualified) is registered in the FR.
The static grid prequalification is performed for the most critical separately up and down products among those selected by FSP that may cause network congestion.
The status of FSP (registered) is registered in the FR.
