Simulation based evaluation of large scale waste heat utilization in urban district heating networks: Optimized integration and operation of a seasonal storage

This paper shows, that a strategic operation of the seasonal storage could increase the number of charging cycles and thereby increase significantly the revenues of the system. This is mainly due to the combined utilization of the storage in a seasonal approach to shift the waste heat from summer to the winter period and as a short term buffer. Thus, the profits from actively participating on the electricity market with the existing combined heat and power (CHP) plants are increased.
