Techno-economic analysis of implementing thermal storage for peak load shaving in a campus district heating system with waste heat from the data centre Haoran Li1*, Juan Hou1, Yuemin Ding1, and Natasa Nord1 1 Department of Energy and Process Technology, Norwegian University of Science and Technology (NTNU), Kolbjørn Hejes vei 1 B, Trondheim 7491, Norway Abstract.
The Federal Energy Regulatory Commission (FERC) has given a definition of electric storage resources (ESR) to cover all ESS capable of extracting electric energy from the grid and storing the energy for later release back to the grid, regardless of the storage technology. A large number of ESS have recently started to participate in the wholesale markets (e.g.,
Energy storage demand power and capacity at 90% confidence level. As shown in Fig. 11, the fitted curves corresponding to the four different penetration rates of RE all show that the higher the penetration rate the more to the right the scenario fitting curve is.
Energy storage power correction During peaking, ES will continuously absorb or release a large amount of electric energy. The impact of the ESED on the determination of ES capacity is more obvious. Based on this feature, we established the ES peaking power correction model with the objective of minimizing the ESED and OCGR.
Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.
The unique advantages of energy storage (ES) (e.g., power transfer characteristics, fast ramp-up capability, non-pollution, etc.) make it an effective means of handling system uncertainty and enhancing system regulation [, , ].
Due to the limitations of the maximum power of conventional units, the system needs a larger discharge power provided by ES to participate in peak shaving when the power of RE is small (e.g. Fig. 7 (Typical day 2 12:00 to 20:00 p.m.)).
In Ref., an operational cost model for a hybrid energy storage system considering the decay of lithium batteries during their life cycles was proposed to primarily minimize the operational cost and ES capacity, which enables the best matching of the ES and wind power systems.
