Analysis on Capacity Evaluation Model and Optimization Algorithm for Meshed Power Collection Grid

Abstract:

To safeguard distributed power smoothly being sent out, the meshed power collection grids were proposed. By comparing reliability of radial and meshed grids, the capacity evaluation model for meshed power collection grids was established in terms of electricity revenue and cable costs, and the 2.5MW double-fed wind turbine’s evaluation data was divided into six levels according to 0-700 million income, and the capacity optimization algorithm was provided based on genetic algorithm, and optimal routing solutions and capacities under different income levels were proposed. The results show that 7 * 7 and 5 * 15 schemes have best income and capacity, and the effectiveness of evaluation model and optimization algorithm is proved.
