AI Technical Summary
In the existing technology, manual transmission network expansion planning is greatly affected by human subjective factors, resulting in low planning accuracy and efficiency.
By obtaining the attribute data of wind power generation equipment, photovoltaic power generation equipment, transmission network and load, the wind power output, photovoltaic output and load absorption data are determined, and a comprehensive analysis is performed using the preset transmission expansion planning model to construct the objective function of minimizing investment cost and annual congestion surplus, and determine the target transmission expansion planning scheme after connecting wind and solar power generation equipment.
It improves the accuracy and efficiency of transmission network expansion planning, can better meet load power demand, reduce operational risks, and promote the integration of renewable energy power generation and power grid.
