4 Frequently Asked Questions about “Substation energy storage capacity configuration - ID Solar Energy Systems”
Do large capacity substations increase power supply capacity?
Large capacity substations in terms of capacity and quantity of transformer can increase the power supply capability of a closed area, but also require a greater number of incoming and outgoing lines from different voltage levels.
Are large-capacity substations adaptable?
With the increasing penetration of renewable energy, the adaptability of the existing substation planning model in terms of capacity and quantity of transformer needs to be further studied when preferring large-capacity substations.
How to calculate construction and operation cost of a large capacity substation?
It is assumed that the supply radius of the large capacity substation is R, and the capacity of transformer is S i and N (t) is the number of transformers in the substation in t th year. Then the construction and operation cost of the substation in the i th year can be obtained as follows: (9) f ( i) = f 1 + f 2 + f 3 + f 4 + f 5
What are the optimization results for large capacity substation (80 MVA)?
The optimization results for large capacity substation (80 MVA) When the capacity of the transformer is selected as 80 MVA, 2 transformers were put into use for the substation in the first year. When considering renewable energy access, the third transformer was introduced into the substation in the third year.
