Efficient linear network model for TEP based on piecewise McCormick relaxation

Electrical Power Systems Reinforcement through Overall Contingency Index Analysis and Improvement

“…By using the OPF-AC in an EPS, the values of the power generated by each generation unit are obtained [11], as well as active and reactive powers [13], losses in the system [19], and this includes the maximum charge ability. The researchers in [20] carried out the charge ability analysis and ranking of contingencies, while [21] obtained the magnitude of the voltage, currents in buses and TL, the flow through the elements of the EPS, losses, voltage profile, and angular deviation; the parameters used to find solutions are [4] voltage profiles and angular deviation.…”

“…In [10], the cascading failures of an EPS lead to affecting the operation of transmission lines and factors such as reliability and economy. In [11], the primary solution is to determine the exact location to build transmission lines that are missing or that must be re-powered.…”

A Hybrid Optimization Method Combining Network Expansion Planning and Switching State Optimization

“…The general solution strategy in the mathematical programming context is to apply different relaxation schemes to consider the non-linear power flow equations in power system planning [6]- [8]. Promising results are demonstrated by these relaxation and approximation methods on a wide range of problems, including OTS [4], [9] and NEP problems [10], [11]. However, no optimality is guaranteed and obtained solutions are often not AC-feasible when applying relaxations [12].…”

Resilience‐based tri‐level framework for simultaneous transmission and substation expansion planning considering extreme weather‐related events

“…Reinforcing the power distribution network infrastructure with the consideration of small-scale thermal generation units was carried out by a shuffled frog leaping optimisation algorithm in [30] and a honey bee mating optimisation algorithm in [31]. In [32], a leastcost linearised static model was represented for efficiently augmenting the power transmission lines using a piecewise McCormick relaxation technique. In these studies, from the perspective of modelling, short-term remedial corrective strategies (e.g.…”

“…The maximum admissible number of newly installed transmission substations on each bus of the transmission network at period t and at all periods of the planning horizon is addressed by constraints (29) and (30), respectively. The maximum permissible number of existing augmented transmission substations on each bus of the transmission network at period t and at all periods of the planning horizon is represented by constraints (31) and (32), respectively. The restrictions associated with the total accessible budget for the…”
