“…The N-1 reliability criterion is integrated into the DCOPF formulation for the purpose of switching decision making in [22]. Topology control for load shed recovery (LSR) via the DCOPF-based MIP Heuristics (MIP-H) is recently proposed in [23].…”

“…The BST algorithm takes the following inputs: all DCOPF inputs, the contingency setĠ ∪K, the potential amount of load shed 1 that may be shed following a contingency, denoted by LSĠ ∪K , the time interval between two consecutive line switches, , the minimum desired improvement in LSR percentage between a child node and its parent, ı (say 0.01%), and the maximum number of levels in the BST, H. The BST algorithm comprises three procedures: (1) LSĠ ∪K calculation (as described in [23]); (2) initialization procedure to create the root node and place it in the BFS queue; and (3) the main procedure at every node after it is taken out of the BFS queue.…”

With the rapid load increase in some countries such as China, power grids are becoming more strongly interconnected, and the differences between peak and valley loads are also increasing. As a result, some bulk power systems are facing high voltage limit violations during light-load periods. This paper proposes to utilize transmission switching (TS) to eliminate voltage violations. The TS problem is formed as a mixed-integer nonlinear program (MINLP) with AC power flow constraints and binary variables. The proposed MINLP problem is non-deterministic polynomial hard. To efficiently solve the problem, a decomposition approach is developed. This approach decomposes the original problem into a mixedinteger linear programming master problem and an AC optimal power flow slave problem that is used to check the AC feasibility. Prevention of islanding is also taken into consideration to ensure the feasibility of the TS results. The modified IEEE 39-bus and IEEE 57-bus test systems are used to demonstrate the applicability and effectiveness of the proposed method.

“…For this reason, some changes will happen in traditional power system operation [2][3][4]. Today, it should be considered that multiple switching actions cause the changes on the system operation [5]. Furthermore, cascading events caused by different faults can cause multiple switching actions [6].…”

Power systems are being expanded day by day with a more complex structure. The system topology always changes due to faults and/or operation requirements. Therefore; malfunctions might occur in the protection system which is one of the most important components for the system reliability, stability and economic operation. Distance protection relays fulfil the main protection function of the power transmission lines. In this study, an algorithm is created which recalculates the distance protection relay setting values depending on the topological changes of the network. The algorithm verified by testing on a selected area from the Turkish National Power Transmission System which comprises 154 kV 28 buses. Modelling of the power system carried out with Dig silent Power factory software. The algorithm is created in the DPL (Dig silent Programming Language) platform.
