How to allocate energy storage when there are multiple transformer capacities

What is the optimal allocation method for DES and transformer capacity?

A two-layer optimal allocation method for DES and transformer capacity is proposed to coordinate configuration of DES and transformer capacity. A DES location method based on the standard deviation of network loss sensitivity is proposed.

Does energy storage capacity allocation enhance economic benefits?

It can be seen that appropriate energy storage capacity allocation highlights economic benefits. Therefore, the scheme of coordinated configuration of DES and transformer capacity is the optimal overall economy.

Which scheme has the best effect on energy storage and transformer capacity?

Therefore, scheme 3 (coordinated planning of energy storage and transformer capacity) has the best effect. 5.3.2. Economic benefit analysis of DES economic dispatching model

What is a two-layer optimal allocation method for distribution network transformer overload?

Conclusion This paper aims at the problem of distribution network transformer overload operation caused by small output of DG, a two-layer optimal allocation method for DES and transformer capacity is proposed. The method coordinates the configuration of DES and transformer capacity.

How to calculate capacity expansion cost of transformer?

Capacity expansion cost of transformer F ex T, it can be expressed by Equation (28). Capacity expansion cost of transformer include two parts, one part is the transformer investment cost Fex, it can be expressed by Equation (29), the other part is the transformer operation and maintenance cost FT,OM, it can be expressed by Equation (30).

How can a large capacity decentralised energy storage system improve distribution network planning?

When a large capacity decentralised energy storage is installed on each line, a better control effect can be achieved. However, the economic cost is very high. In case 5, the optimal distribution network planning scheme is obtained using energy storage allocation and line upgrading.
