Sažetak
Growing presence of urban regeneration projects which reorganize and upgrade existing urban and former industrial areas, city neighbourhoods or even whole districts, is strongly related to the implementation of renewable energy sources. Interdependencies between different energy carriers and the corresponding technologies lead to synergy effect, which can have a significant impact on an energy system. Heat storage is in most cases a cost effective way to increase both the flexibility and the operational efficiency of low carbon systems thus providing technical, economic and environmental benefits. The added flexibility provides more possibilities for the utilization of renewable energy sources, which consequently reduces the share of fossil fuel consumption and thereby greenhouse gas emissions. Additionally, power to heat technologies such as heat pumps or electric heaters, can be used for integration of power and heating systems. This can increase the flexibility of the power sector, and moreover, the system’s capacity to utilize intermittent renewable energy sources such as wind and solar. The goal of this work is to develop, demonstrate and validate a model capable of optimizing the heat storage capacity for small solar district heating system, as well as its operation on an hourly level with a time frame of one year. Such approach allows the model to choose between short term and seasonal heat storage systems which take into account both the hourly and the seasonal variations in the operation of the system. The model has been tested and validated as a case study on the small neighbourhood Trnsko which is located in the southern part of Zagreb.
