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).
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
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.
First, the energy storage capacity requirements is analyzed on the basis of the transformer overload requirements, and analyzing the correspondence between different capacities of energy storage and transformer expansion capacities.
For the area-constrained ZNE case, transformer constraints add 631 kW of PV (5.6% increase), 2,259 kWh of EES (12 fold increase), and 10,844 kWh of REES (inexistent beforehand).
In order to solve the problem of transformer overload, it is usually adopted to expand the capacity of transformer directly, but the limitation of this method is that the expansion part is only used at the moment of transformer overload and the investment cost of expansion is high , .
