Use Cases of Digital Models and Digital Twins in Power Supply Systems of Large Consumers

Large industrial consumers have become active participants in power systems, influencing reliability, stability, controllability, and market prices. Modern enterprises operate complex internal power supply systems, deploy backup generation, demand-side management, renewable energy sources (RES), and energy storage systems (ESS). This reinforces the interdependence between consumers and the power system and raises requirements for information exchange with DSO and ISO. Nowadays, effective coordination requires the exchange of up-to-date mathematical models across multiple time horizons, from real-time operation to long-term planning.
