“…Z s represents the series impedance of T s , while Z sh represents the shunt impedance of T sh , and an auxiliary bus (k) represents the terminal of the UPFC. It is worth to mention that modeling UPFC into Newton Raphson load flow based on voltage source modeling needs complex modifications in the Jacobin, the correction, and the mismatch matrices to incorporate the parameters of the UPFC as state variables which include ΔV s , ΔV sh , Δθ s , and Δθ sh as (1) where F is the main Jacobian matrix of NR power flow, while F 1 , F 2 , and F 3 are submatrices of devices equations. B is the main mismatch matrix of the NR power flow, while B 1 is the mismatch of control device equations.…”

Summary Unified power flow controller (UPFC) is utilized to regulate the bus voltage as well as the power flow through a power system. A solution of optimal power flow (OPF) problems with UPFC is a crucial and complex task due to the required modifications for considering the parameters of UPFC. This work proposes a simplified UPFC modeling into an OPF code in order to avoid the programming complexity. Moreover, the solution of an OPF problem with a UPFC model is obtained by a recent physical‐based optimization technique called lightning attachment procedure optimization (LAPO). Different objective functions including minimizing fuel cost and fuel cost with valve point effect (VPE), reduction of emission, improvement of voltage profile, and improving the voltage stability index are considered. The proposed algorithm is tested using the standard IEEE 30‐bus system. The results obtained by the proposed algorithm are compared with those obtained by other optimization techniques. However, the obtained results verify the applicability of the simplified UPFC model in OPF.

“…Clustering Criterion: At this stage -means is used to assign the nodes into clusters. -means iteratively minimizes the objective function: (25) where accounts for the distance between a node and a cluster centroid . This optimization iterates until the movement of the -centroid points falls below some minimum threshold or a maximum number of iterations is reached.…”

“…Contradicting its motivation it uses geographical shortest paths as a distance metric between load nodes and generation, which is unsound and computationally prohibitive for realistic size networks. Fuzzy logic has also been used to identify voltage control zones [24], [25] where each node has a degree of belonging rather than belonging completely to one zone, prior to crisp clustering. An approach using fuzzy -means is introduced in [25], and has demonstrated robustness for various operating conditions in the network.…”

Hierarchically structured automatic voltage control (AVC) architecture has attracted increased interest as networks operate closer to their capacity limits. Hierarchical AVC enables wide-area coordinated voltage regulation (CVR). Due to the inherent complexity of the task, it is based on reduced control models, i.e., simplified models of the system suitable for voltage control. It is a fact however that a single reduced control model (static RCM) cannot be optimal for all network configurations and operating conditions. In pursuit of an improved CVR, this paper investigates the applicability of zoning methodologies in adaptively determined RCM. It further argues that the selection of a zoning methodology affects not only the CVR operation, but also its robustness to erroneous data and proposes a comprehensive generic framework for evaluating its performance. Lastly, it extends and evaluates several zoning-based control model reduction methodologies: namely, hierarchical clustering employing two different proximity metrics, spectral-way and fuzzy-means, on both static and adaptive schemes.

“…Estos dispositivos intercambian corriente reactiva capacitiva o inductiva [5]. Por otro lado, los Statcom (Static Synchronous Compensator) son un tipo de Facts más avanzado, cuya corriente reactiva de intercambio no depende de la tensión a la que está conectado [6]. El compensador serie controlado por tiristores (sigla-TCSC) es un Facts que permite un ajuste rápido y continuo de la impedancia en una línea de transmisión, y su estructura básica consta de un banco de condensadores en paralelo con un reactor TCR (Thyristor controlled reactor) [7].…”

This article shows a methodology for the technical and economic analysis of the incorporation of Facts devices in electrical power systems. The methodology proposed consists of a deterministic stage and a stochastic stage which involve aspects of technical and economic feasibility, respectively. The first stage is based on a non-linear binary mixed programming model developed at AMPL in order to minimize generation of safety given the location of a Facts device. The second stage employs an energetic model based on a stochastic dynamic dual programming (SDDP) which determines the cost-benefit ratios of the incorporation of Facts for different hydrothermal series. In order to illustrate the applicability of the methodology proposed, a case study is shown in the Colombian electrical system, taking into account the incorporation of a Statcom in the Atlantic Coast. Additionally, it is shown that the solution proposed resolves oscillatory instability problems of power, identified in minimum generation scenarios before critical contingencies.
