A Power Grid Network Planning Method Based on the MTPS Optimization and Safety Analysis

A reasonable grid structure is a basic condition for ensuring the safety and stability of the power system, and a prerequisite for ensuring reliable electricity use for the majority of industrial and mining enterprises, residents, and public services. This paper proposes a power grid structure planning method based on the MTPS optimization and safety analysis. This method first established the muti-traveling salesman problem (MTSP) model for the power grid structure planning, then solves this model through the dynamic programming algorithm. Therefore, the shortest planning path of the power grid can be obtained. Then this method establishes the DC power flow of power grid by selecting the typical line parameters for the planning path of the power grid. Under the N-1 safety constraint, the type and number of the line is decided. Finally, the AC power flow model of the planned power grid is realized to ensure N-1 safety. The simulation results of the real power grid show that the proposed method guarantees the economy and security of the planned power grid construction.
