FSkar - FINANCIAL SETTLEMENT OF K∆𝑓, ACE AND RAMPING PERIOD
From June 1, 2021, HOPS is applying the process of financial settlement of unintended exchange - FSkar.
What is FSkar?
Due to the physical nature of an interconnected network, there are unavoidably deviation between the intended exchange and the actual physical flow – unintended exchange. There are three different components of these deviations:
- frequency containment process energy - FCP energy - results from the activation of FCR across the synchronous area and is an intended component,
- ramping period energy - RPE - results from the application of ramps to the scheduled exchanges and is also an intended component, and the third component is
- actual unintended exchange.
The aim of the FSKAR process is to perform the accounting and settlement of these three components with a price.
According the EBGL (Art. 50(3) and 51(1)) settlement of the unintended exchange with price is required. FCP energy and unintended exchange are settled at the same price (based on day-ahead market prices) and the RP energy at a zero price.
Input parameters for the calculation are the scheduled energy exchange Esch , the exchanged energy between the LFC areas/blocks Eex as reflected in the accounting data, the frequency deviation ∆𝑓 and the K-factor.
The output of the accounting function are EFCP , ERP and Eue.
