“…In [132], the steady-state security region model using OTS is proposed and solved by a decomposition approach. Additionally, [133] discusses the impact of OTS on a hybrid wind/PV generation, where the AC-OPF model is solved using a combination of a genetic algorithm and a non-linear primal-dual interior point algorithm. Lastly, [134] proposes a stochastic OTS model that considers the uncertainty associated with both wind and PV to minimize grid vulnerability and reduce generation cost.…”

The integration of variable renewable energy sources (RES) into power grids has resulted in a more complex operating environment for power system operators (SO), necessitating the need for increased grid flexibility. This is crucial for utilities, as the cost-effective utilization of existing infrastructure is necessary, given the prolonged construction period and high investment costs associated with building new power delivery facilities. Under the umbrella of smart grid, optimal transmission switching (OTS) is a cost-effective transmission technology that can alleviate concerns related to network congestion, limited transmission capacity, and high penetration of renewables. OTS is a concept that is integrated into the optimal power flow (OPF) problem such that it provides SO the choice to temporarily switch one or more lines out of service from the network. OTS is shown in the literature to have economic benefits, reduce operational cost, relieve network congestion, serve as a corrective mechanism for reducing voltage violations, improve system reliability, and minimize system loss. Despite the significant attention given to OTS by researchers over the past decade, no extensive review paper exists on the topic in the literature. Therefore, this paper provides a state-of-the-art overview of the OTS problem. The concept of OTS is explained by approximating the alternating current OPF problem into a linear direct current OPF problem. Various alternative models of the OTS problem proposed in the literature are discussed. The paper also analyzes the interaction between OTS and other flexibility options such as Dynamic thermal rating (DTR), Energy storage systems (ESS), and RES. Furthermore, the paper presents the general framework and impact of the short-term OTS problem on long-term expansion planning problems. Finally, an extensive literature review on the impact of OTS on system reliability is provided.

The large number of uses of electrical energy encourage humans to identify and utilize new primary energy sources such as wind power. However, wind energy is unstable which can affect the stability of power flow in conventional power systems. The intermittent wind energy prompted the development of power flow analysis methods. In this study, the IEEE 26 bus data system is used as a method validation, and the 150 KV 29 bus data system in South Sulawesi which is integrated with wind power plants as a case study. The method used is the hybrid update velocity inertia weight algorithm (IWA) and the constriction factor algorithm (CFA) abbreviated as PSOHIC. The simulation results of the South Sulawesi system data integrated with the wind power plant show that PSOHIC converges at the 9th iteration faster than IWA in the 29th iteration and CFA in the 20th iteration. The power loss using the PSOHIC method of 18,155 WM/h is lower than the existing system, which is 19,267 WM/h, or the power loss has decreased by 5,7691%. The generation cost using PSOHIC is 5.
