6 FAQs about [Energy storage cooling system matching]
How can heat storage devices improve the utilization rate of waste heat?
Heat storage devices can improve the utilization rate of waste heat [ 3 ]. Adding renewable energy generation methods, such as photovoltaic power generation and wind power generation, to the traditional CCHP system can improve the environmental protection of the CCHP system and reduce the dependence of the system on non-renewable energy.
How can energy generating units provide heat and cooling energy?
Since energy generating units also produce heat in addition to electricity, so the heat generated can be used to supply heating and cooling energy to buildings with the help of hot water heat exchangers and absorption chillers. The suggested technique was compared with the GA optimization technique.
How ESS Mt & PV work together?
When the PV can generate electricity, ESS, MT, and PV together meet the electricity balance of the system. From 20:00 to 24:00, ESS, MT, and the grid work together to meet the electricity demand of the system. For scheme 2, the scale of self-configured energy storage equipment in CCHP systems is smaller.
How are heating and cooling load demands met?
The heating and cooling load demands are met in the same way for the three operating schemes. First, it is determined whether the waste heat recovered by HR meets the system heat demand. If the waste heat is larger than the demand, the excess heat is saved in the TST. If the waste heat is insufficient, TST is given priority for heat release.
Does ESS have more energy storage batteries than CCHP?
From the data in Table 7, it can be found that compared to the CCHP system in scheme 2, which is configured with energy storage equipment alone, in scheme 1, ESS can be configured with larger capacity energy storage batteries.
How can energy storage equipment reduce economic costs?
In terms of reducing economic costs, this study proposes a new energy storage equipment configuration scheme. Through the coordination of energy storage equipment and photovoltaic power generation equipment, the demand of the system for grid power supply is reduced.
