| Abstract: | The paper provides an analytic and appraisal method for optimization of coordination between transmission grid investment and power grid reliability.A cost function is deduced,which reflects the change of uplift cost of transmission constraint with the change of the transmission constraint value.A mathematical model is established for optimized reliability analysis of transmission grid in a whole year and experimental verification is carried by a practical example.The subject of establishing market mechanism for financing of transmission expansion project is studied and relevant plans and suggestions are proposed. |
