“…This philosophy results in a three-dimensional graph that contains the security boundaries with respect to the power generated in each group. In order to simplify the visualization, it is convenient to plot a nomogram, which is an orthogonal projection onto one of the generation planes [26]. The application of nomograms in voltage security analysis is discussed in [27], that argues how this graphical tool can be useful for system operators.…”

“…Sun et al 6 proposed an online dynamic security assessment scheme for large‐scale interconnected power systems that identify stability problems for operating conditions and provide guidelines for preventive control. Netto et al 7,8 described a probabilistic approach for determining the voltage‐related safe system operating region combining the radial exploration of operating conditions of the conventional methodology presented by Almeida et al 9 They also described a probabilistic contingencies analysis, considering the contingencies that have higher chances to occur. Javan et al 10 reconstructed the static security regions (SERs) in a low‐dimensional space by increasing in stress extent along with several loading directions until the static voltage stability, generators output, or transmission lines reach their limit.…”

“…These techniques also need to deal with a large amount of simulation data to display the results simply and understandably. In this context, the detailed construction process of the SSRs was presented by Almeida et al 9 The SSR is a very robust tool based on VSA methods to analyze large‐scale power systems' security margins. It can also be helpful for offline studies such as the analysis of impacts of load modeling in power systems and the effects of generator remote voltage control in security margins 23 .…”

Summary A static security region is a tool that provides information on the steady‐state security conditions, for a given operating point, of a power system in an efficient way. Although this tool aims to be used in the online environment, one of its main characteristics is the high computational time required in the construction process. In this context, this article proposes a new methodology to construct these regions based on the particle swarm optimization (PSO) algorithm to improve computational performance. The proposed adjustments for the PSO algorithm parameters are detailed as well as the process to generate the initial population. The proposed methodology is validated through the study of two power systems. The first one is the well‐known New England system, and the second one is an equivalent of the southern Brazilian system. The presented results validate and clearly indicate the effectiveness of the proposed technique.

“…The dynamic security risk assessment refers to the ability of the system to stable transition to a new stable operating state after a disturbance occurred, and gives appropriate reference solutions for necessary preventive measures and remedial measures [6], [7]. The static security risk assessment method can quantitatively describe the possibility of event and the severity of its consequences, so this method has been widely recognized [8]- [13]. A security risk assessment scheme of power system using fast probabilistic power flow is proposed in [10] and a two-layered parallel static security assessment program based on Newton-Raphson method is presented in [11], which are both applied to large-scale grids.…”

Due to the lack of the support from the main grid, the islanded hybrid ac/dc microgrid will more likely cause the power flow severe fluctuation and even the microgrid to be split once a serious contingency occurs. To maintain the security and stability of the system under such a condition, this paper proposes a new static security risk assessment of the islanded hybrid ac/dc microgrid considering that the hybrid ac/dc microgrid was split. First, this paper presents a static security analysis criterion to determine the post-contingencies splitting scheme and a new load-shedding strategy to achieve power balance of subsystems. On this basis, a probabilistic power flow calculation method based on Levenberg-Marquardt with a nonmonotone line search (LMNL) algorithm is applied to calculate the probabilistic power flow of the islanded subsystems. Finally, the probability distribution of static security risk assessment indexes, including the dc loss load risk, ac loss load risk, and interlinking converter (ILC) active power limit violation risk, are obtained. The simulation results on the test system demonstrate the necessity of considering the hybrid ac/dc microgrid was split, and prove the feasibility and effectiveness of the proposed method. INDEX TERMS Islanded hybrid ac/dc microgrid, interlinking converter, static security risk assessment, subarea load-shedding strategy, LMNL algorithm.
