Integrated control of centralized and renewable heat sources with peak demand compensation

The system under investigation was heat distribution network servicing a number of buildings from the central source, while some buildings are supplied from biomass boiler. The key objectives of this research were to develop an integrated system allowing control and monitoring of the operations of the sources of heating energy (including renewable energy sources) and to identify ways to optimise energy consumption. An important problem of this strategy consists in keeping peek demand of energy below the maximum power of the external energy sources. The proposed algorithm is model-based and compensates peak power energy deficiency of a building.
