What is the heating and cooling load of the Industrial Park?
It is assumed that land area occupied by the industrial park is 26 km 2, and 24 km 2 is adopted for buildings. The heating and cooling loads of buildings are shown in Fig. 4 (a), which are simulated by the hourly air temperature. Among them, the maximum cooling load is .78 kW, and the maximum heating load is .52 kW.
What is the electricity load required for the production of industrial park?
The electricity load required for the production of the industrial park is shown in Fig. 4 (b). As can be seen, the electricity load in summer and autumn is 20% higher than that in spring and winter. From Fig. 4 (c), the minimum of hydrogen load is 105.458 kW and the maximum is 339.196 kW.
Can a long-term hydrogen storage model be used in industrial parks?
For industrial parks where hydrogen is commonly utilized, a feasible solution for planning the coupling of hydrogen and other energies is provided in this paper. In the aspect of storage modeling, a long-term hydrogen storage model considering different time steps is newly proposed.
What are the two types of energy storage?
The remaining energy storages are thermal energy storage (TES) and electric energy storage (EES). Specifically, the load requirements of heat and electricity are satisfied by the charging and discharging of those energy storages.
What is hybrid energy storage?
In IN-IES, hybrid energy storages are considered. Specifically, EES, TES, and HS are applied to short-term energy compensation, while LHS is employed to overcome the seasonal mismatch between renewable energy generation and energy consumption. Seasonal energy storage is characterized by low annual cycle times.
Is a long-term hydrogen storage model a seasonal energy storage model?
The long-term hydrogen storage model proposed in this paper has the characteristics of seasonal energy storage, while the calculation time is shortened by it. By the introduction of hydrogen compressor models considering different overall efficiencies, the planned compressor rated capacity can be decreased.
