The TNEP problem is often developed using the direct Revised 30 10 2023 current power flow DCPF method. However this approach takes no Published 30 10 2023 account of the power loss and the effect of reactive power flows. In addition ensuring the security of power systems for a single outage of any system element known as the N 1 security criteria plays a vital role in planning and KEYWORDS operation problems. This paper presents a mixed-integer linear programming Transmission network MILP -based method with the aim of optimizing the transmission grid expansion planning TNEP topology considering power loss reactive power flows and the N 1 criteria. The adjustment technique of branch limits is deployed with a view to the Mixed-integer linear incorporation of the influence of reactive power flows. The iteration programming MILP technique is proposed to consider the N 1 criteria in the network planning Power loss process. The evaluation of the proposed method is implemented on an IEEE The N 1 security criteria 24-node transmission system in which the MILP model is solved using the CPLEX tool under GAMS programming language and the N 1 contingency Reactive power analysis is performed using POWERWORLD software. The planning results show that 19 transmission lines with a total investment of M need to be built for the security operation of power systems according to N 1 criteria.
