ACCUMOS

The increasing share of renewable but also secondary sources in energy systems raises the need to solve the problem of time mismatch between immediate production and immediate consumption of energy, a typical representative of this phenomenon is the installation of large electric boilers to use immediate surplus of electricity for heat production. One of the means of compensating for the disparity between the balance of production and the balance of consumption is energy storage, in this case storage in the form of useful heat. A relatively large potential for accumulation is offered by thermal energy supply systems (TES), which are able to absorb (accumulate) and then use immediate surpluses not only from the production of their own heat sources, but also surpluses of production in the electricity system (e.g. from photovoltaics), or surplus capacity of other sources such as waste-to-energy plants (WET plants), biogas plants (BPS), etc. Heat can be stored in static accumulators built at the sources (volumetric insulated water tanks), in the heat network (utilisation of the water content of the network) or in distributed heat accumulators of various designs located at selected customers.

This software (ACCUMOS) was created with state support of the Technology Agency of the Czech Republic within the THETA Program (Project No. TK05020004 entitled “Controlled predictive heat storage in SZTE”).

ACCUMOS is a software for modeling phenomena related to effective heat storage in thermal energy supply systems.

This product can:

  • predict free or needed storage capacities (dependence of surplus production on time, outdoor temperature, sunlight, wind, or other factors);
  • model storage processes (charging, transfer, and discharging processes on time, power, medium temperatures, transport delays, etc.);
  • predict heat consumption patterns (dependence of needs on time, outdoor temperature, sunlight, wind, or other factors).
