Document Type and Number:
WIPO Patent Application WO/2022/105944
Kind Code:
A1
Abstract:
A method for calculating the optimal load capacity of a 10 kV feeder taking into account the impact of different load structures and reliabilities, comprising: establishing a 10 kV feeder optimal load capacity calculation model, the calculation model taking total distribution line investment and power grid revenue as target functions, and taking an equipment duty cycle constraint, an equipment load matching constraint and a reliability constraint as constraint conditions; and then, calling the fmincon function in a MATLAB simulation to solve the 10 kV feeder optimal load capacity calculation model. The method for calculating the optimal load capacity of a 10 kV feeder taking into account different load structures of the present invention provides a method for calculating the optimal load capacity of a 10 kV feeder that incorporates reliability and economicalness, and can be applied to the calculation of optimal 10 kV load capacity under different load structures. In the method of the present invention, the resource utilization level of a 10 kV feeder is evaluated reasonably, and a reference basis is provided for load planning and operation level analysis for the 10 kV feeder.
