The diagram illustrates the district heating optimisation algorithm concept. It is divided into two main sections: District Digital Twin and Services. The District Digital Twin section includes DHIM, SCADA, Data mart, and DHNx. DHIM, which stands for District Heating Information Model - CityGML, provides network topology. SCADA, which stands for Operation data, provides real-time operation parameters. These parameters are fed into the Data mart, which then provides data to DHNx, the District Heating Performance Simulation, for predicting heat and pressure losses. The Services section includes Production Forecast and Performance Optimisation. Production Forecast uses demand profiles and PV production prediction to provide data for services. Performance Optimisation uses this data to recommend operation parameters. User-edited operation parameters are fed back into DHNx, completing the loop.District heating optimisation algorithm concept
