The maximum capacity of a substation is equal to 100% of the rated capacity of its transformers. The total capacity of DER (Distributed Energy Resources) is equal to 25.6% of the maximum capacity of the substation. This ratio is 25.5% when the substation has three transformers and 27.8% when the substation has four transformers. The aim of this annex is to show how the capacity in a substation can be calculated.
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.
The substation is fed 1316 MW power from 3 generating stations A,B,C through 400 KV single circuit lines working at around 87% loading. The power is received on 400 KV busbar (double main and transfer bus scheme).
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.
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
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.
