Factors affecting the power and capacity of energy storage systems

What is the capacity of electricity storage equipment?

The capacity of electricity storage equipment is closely related to the installed capacity of a renewable energy system. Presenting a PV power generation system as an example, the installed capacity of PV power generation and the storage capacity of the battery must match each other.

How to determine the capacity of energy storage equipment?

Considering the flexible potential and cost factors, the capacity of energy storage equipment can be reasonably determined in accordance with SSES and SES. The capacity of electricity storage equipment is closely related to the installed capacity of a renewable energy system.

How does the capacity of heat storage equipment affect energy storage?

In addition, the capacity of heat storage equipment is directly related to the number of energy storage times. For example, the energy storage equipment is required to have a large capacity to store the cold/heat required for 1 day at one time (single-stage energy storage, SSES) during the valley power consumption period.

Does power flexibility affect electricity storage capacity?

In the PLDP case, the minimum electricity storage capacity is only used to prevent the occurrence of the light abandonment phenomenon. Even if a small amount of power flexibility is provided under certain circumstances, then the magnitude of this power flexibility cannot affect the electricity storage capacity.

Why do we need a minimum electricity storage capacity?

Under the MPFPH situation, the minimum electricity storage capacity can ensure the maximum flexible potential during the peak period of electricity consumption. Moreover, storage capacity is relatively large, and thus, it can also prevent the occurrence of the light abandonment phenomenon.

What is the energy storage capacity of cold/heat storage equipment?

The energy storage capacity of cold/heat storage equipment depends on the difference between the cold/heat load of buildings and the thermal flexibility provided by other flexible sources. The maximum value of the thermal flexible potential is the cooling or heating load value of buildings.
