A Mathematical Approach to Simultaneously Plan Generation and Transmission Expansion Based on Fault Current Limiters and Reliability Constraints

Today, generation and transmission expansion planning (G&TEP) to meet potential load growth is restricted by reliability constraints the presence of uncertainties. This study proposes constrained method for integrated renewable energy sources considering fault current limiter (FCL) placement sizing N-1 security. Moreover, an approach dealing with uncertain events adopted. The proposed model translates into a mixed-integer non-linear programming model, which complex not easy solve. problem was formulated as tri-level problem, hybridization framework between meta-heuristic mathematical optimization algorithms introduced avoid linearization errors simplify solution. For this reason, three techniques were tested. methodology conducted on Egyptian West Delta system. numerical results demonstrated efficiency integrating G&TEP FCL allocation issues in improving power system reliability. Furthermore, effectiveness algorithm solving suggested validated comparison other algorithms.
