Ice energy storage regulation

Can ice storage air-conditioning reduce the investment and loss of Bess?

This paper proposes a new energy management strategy that reduces the investment and loss of the battery energy storage system (BESS) by applying ice storage air-conditioning (ISAC) to the microgrid. Based on the load characteristics and BESS investment, the capacities of the chillers and the ice tank are analyzed.

What is the optimal ice storage strategy?

Because the ice storage capacity (577 GJ) was higher than the sum of the peak and super-peak cooling loads (435 GJ), the optimal strategy was to melt surplus ice during flat hours (7:00 to 10:00 and 21:00 to 22:00) to reduce the use of regular cooling, resulting in operating cost savings of 15.7 % compared to the conservation strategy.

Can ice storage air-conditioning reduce the investment and loss of battery energy?

Thus the management of the cooling demand side can regulate the peak–valley demand and stabilize power fluctuations. This paper proposes a new energy management strategy that reduces the investment and loss of the battery energy storage system (BESS) by applying ice storage air-conditioning (ISAC) to the microgrid.

Why do HVAC systems use ice storage tanks?

This enables operating the HVAC system during periods when clean, renewable power is available and reducing the electric loads when renewable generation is not available or during peak load periods. Figure 1 shows an example of ice storage tanks connected with an HVAC system. Figure 1. TES example: Ice tanks integrated with HVAC system.

What is thermal energy storage?

Thermal energy storage (TES) is one of several approaches to support the electrification and decarbonization of buildings. To electrify buildings eficiently, electrically powered heating, ventilation, and air conditioning (HVAC) equipment such as a heat pump can be integrated with TES systems.

What is the difference between optimal and aggressive ice storage strategies?

The only difference between the optimal and aggressive strategies was that the optimal strategy used regular cooling from 7:00 to 8:00 and ice storage from 22:00 to 23:00, while the aggressive strategy used ice storage from 7:00 to 8:00 and regular cooling from 22:00 to 23:00.
