Identification of Key Substations and Analysis of Impact of Delayed Operation Based on Multi-level Power Grid Evolution Simulation
To effectively identify key substations in the power grid planning scheme and accurately evaluate the investment growth caused by their delayed operation,a set of evaluation indicators and a comprehensive scoring method for the importance of substations were constructed.A multi-level power grid evolution simulation model was proposed to simulate the impact of delayed operation of substations with different levels of importance on power grid construction.The case study shows that the proposed substation importance score is significantly linearly correlated with the incremental investment cost of the power grid caused by delayed substation operation.In the planning and construction of the power grid,for substations with high importance ratings,more attention should be paid to their construction progress to avoid economic losses.
