“…23,24 In AVSR, a two-dimensional plane geometrical concept is used to represent the voltage stability index considering both axes as the active and reactive loading, respectively. In the literature, [25][26][27][28] the network response structural characteristics of complex systems are adopted to derive tools for power system node and branch severity ranking. L-Index, P-index, V/V0 index, and modal analysis were extensively discussed and applied for voltage stability assessment in other works.…”

Summary The performance of a new approach for multiobjective voltage stability constrained‐optimal power flow (VSC‐OPF) formulation is compared with a conventional VSC‐OPF approach for improving the steady‐state power systems security in this paper. The compared OPF problems involve the minimization of the fuel cost and minimization of novel line stability index (NLSI) for case 1 and minimization of fuel cost and maximization of line static stability margin (CBI) for the proposed case 2. Clerc's constricted PSO algorithm modified with the nondominated sorting algorithm is used for obtaining the best solution point for each of the decision variables. Network security constraints and bus voltage limits are considered along with the constraint on permissible line stability margin limit adopting the quadratic penalty model for constraints violations. The approach is tested on a load‐modified IEEE 30‐bus and actual Nigerian 28‐bus systems. From the results obtained, the proposed OPF formulation performed better for simultaneous consideration of voltage stability improvement and line loss reduction.

A reactive power/voltage control strategy is proposed that uses wind turbines as distributed reactive power sources to optimize the power flow in large-scale wind farms and reduce the overall losses of the collector system. A mathematical model of loss optimization for the wind farm collector systems is proposed based on a reactive power/voltage sensitivity analysis; a genetic algorithm (GA) and particle swarm optimization (PSO) algorithm are used to validate the optimization performances. The simulation model is established based on a large-scale wind farm. The results of multiple scenarios show that the proposed strategy is superior to the traditional methods with regard to the reactive power/voltage control of the wind farm and the loss reduction of the collector system. Furthermore, the advantages in terms of annual energy savings and environmental protection are also estimated.

The increased human population along with the advancements and demand for electrical appliances has led to the continuous overstretch of the existing power transmission lines. This tends to overload the transmission system, which results in an excessive power loss and subsequent system outage. Optimal reactive power dispatch (ORPD) is a mechanism deployed to ensure a secured operation as well as an economically viable power system network. ORPD is an optimal power dispatch technique that minimizes transmission line losses while adhering to both equality and non-equality constraints. This research study employed Salp Swarm Algorithm (SSA) to obtain the best vector control variables that give the minimal total active power loss on a standard IEEE 30-bus system network. The result obtained was compared against Particle Swarm Optimization (PSO), where SSA proves to be superior over PSO in the field ORPD.
