**Products Proposed by the OneNet Project** & **Description** & **Harmonized Products** \\ \hline \hline Predictive reactive support & This product’s reactive power is used to respond to a system need that was anticipated during the operational planning period. As a result, activation can be scheduled, reducing pressure on the entire activation time and increasing liquidity. The product can be purchased as a product of reactive power, a capacity product, or both capacity and reactive power products (it can be combined with the reactive power product). To boost market liquidity, this product would be purchased at least once each month (as the duration is less than a month). Information regarding the location of the flexibility is included in this product. The product involves the delivery or absorption of the MVarh through optimum control on the interface between TSO and DSO within predetermined times. It can be applied to voltage control and to minimize distribution grid losses. It is linked to the voltage regulator. & Predictive short-term local reactive product \\ \hline Predictive congestion management for TSO/DSO product & A product for situations where predicted or actual power flows violate the system’s voltage stability or angle stability constraints, as well as the temperature limits of the grid’s components. By using this product, grid-related or market-related measures for forecasted congestions (such as redispatch, countertrading and the usage of active power flexibility) can be purchased. & Predictive short-term local active product \\ \hline Power regulation mFRR & The identification of flexibility needs (secondary and tertiary reserves in a more precise and for a longer period than is currently performed. & mFRR \\ \hline Power regulation aFRR & The identification of flexibility needs (secondary and tertiary reserves in a more precise and for a longer period than is currently performed. & aFRR \\ \hline Severe state prevention/restoration product of flexibility needs are made available. & Improvements in the identification of dangerous system states and the contingencies that might lead to them as well as the improved identification of flexibility resources and the enhanced identification of flexibility needs are made available. & Predictive long-term local active product \\ \hline \hline \end{tabular}

Table 2: Attributes for aFRR, mFRR, and the predictive short-term local active product. aFRR  
aFRR is defined [46] as the active power reserves that are available to restore the system frequency to the nominal frequency. The \"a\" in its name comes from the fact that the activation of this product always takes place automatically. In Table 2, the attributes related to this product can be found.
