SAŽETAK / ABSTRACT:
An efficient and secure data exchange between the Transmission System Operator (TSO), the Distribution System Operator (DSO), and Support Service Providers (SSPs) is crucial for the stability and reliable operation of the power system, particularly in the context of automatic and manual Frequency Restoration Reserves (aFRR and mFRR). The increasing integration of renewable energy sources, the growth of distributed energy resources, and the digitalization of the balancing energy market require optimized and secure communication between relevant stakeholders.
In Serbia’s power system, various types of communication connections exist, differing in their level of directness, infrastructure usage, and security requirements. This paper analyzes potential models for integrating SSPs with TSOs and DSOs through energy and communication infrastructure, considering technical, regulatory, and operational aspects. Special attention is given to challenges and requirements arising from the specific characteristics of the national power grid, addressing communication reliability, data transmission speed, system security, and resilience to cyber threats.
Beyond technical factors, the paper examines the regulatory framework that defines the roles and responsibilities of TSOs, DSOs, and SSPs, as well as the rules influencing the selection of the optimal communication model. The advantages and limitations of different approaches are analyzed, with a particular focus on data protection, network resource availability, and system resilience to potential disruptions.
The paper’s conclusions provide insights into opportunities for improving the existing infrastructure, highlighting key factors for the future development and digitalization of Serbia’s power sector, aiming for greater efficiency, flexibility, and security in the provision of balancing services.
