Implementation and Benefits of Imbalance Netting and the Imbalance Netting Optimization Module in the Power System of Serbia

This paper explores the implementation of the Imbalance Netting mechanism within the European power system, with a focus on its application in Serbia. The Imbalance Netting mechanism enables the reduction of opposing automatic Frequency Restoration Reserves (aFRR) activation by optimizing requests among Transmission System Operators (TSOs). The paper presents the benefits of applying this process, including cost reduction, increased system efficiency, and improved regional cooperation. Specific simulation examples and benefits for Serbia are analyzed. The introduction of this mechanism not only enhances grid balancing but also contributes to reducing operational costs and improving the security of Serbia's power system in compliance with ENTSO-E regulations.
