Peak-valley electricity storage air conditioner

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.

Can large-scale AC loads provide peak regulation services in power systems?

During peak load periods in the summer, AC loads account for approximately 30% to 50% of the total electrical load in urban areas [9, 10]. Hence, it is an interesting study to fully utilize the potential of large-scale AC loads to provide peak regulation services in power systems.

How do AC loads participate in peak regulation?

The framework of AC loads participation in peak regulation is as follows: (1) The DSO publishes the demand for peak regulation in the electricity market based on the pre-scheduling scheme. (2) LA pre-assesses the peaking capacity of the clustered AC loads and bids to the electricity market based on the actual adjustable capacity.

How does air-conditioning contribute to peak regulation?

As one of the most favoured and easily manageable flexible loads, air-conditioning (AC) loads can contribute to peak regulation by temporarily adjusting temperature settings to decrease power usage . Proper control of AC loads does not significantly impair users’ daily usage experience but can generate profits.

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.

Can ffac & Inverter air-conditioning meet peak regulation needs?

Fulfilling the peak regulation needs of the power system solely through generation-side resources proves to be challenging. Large-scale fixed frequency air-conditioning (FFAC) and inverter air-conditioning (IAC) are high-quality flexible load resources.
