The article considers digital dispatching as a market-technological infrastructure that ensures the economy of flexibility and balancing in the electric power industry. A holistic framework of the "digital economy of flexibility" is proposed, linking probabilistic load and RES forecasting, co-optimization of energy, reserves and network constraints, localized price signals and verified execution through SCADA/EMS/DMS/DERMS platforms and aggregators. It is shown that the transition from point to probabilistic forecasts in combination with sliding planning with short calculation intervals reduces excess reservation and the average cost of balancing. Nodal pricing and local flexibility markets reduce off-market redispatch and more accurately reflect deficits in distributed networks. To assess the comparative efficiency of resources, an applied metric CoDF (specific cost of delivered flexibility) is introduced, which allows comparing controlled demand, storage devices and maneuverable generation and adjusting market rules. The need for TSO–DSO coordination to prevent double accounting of services and prioritize local network tasks is substantiated. The key role of cyber resilience (secure telemetry, digital signatures, degradation modes) for scalable calculations and participant trust is emphasized. The results obtained form practical guidelines for regulators, system and network operators when designing markets and digital platforms for flexibility.
