In this paper, an intelligent integrated approach is proposed to control the reactive power and restore the voltage balance in a three-phase power system using particle swarm optimization (PSO), Gaussian process regression (GPR), and support vector machine (SVM). The PSO algorithm is used in offline mode to determine the optimal set of firing angles for the thyristor-controlled-reactor (TCR) compensator according to the smallest fitness value required for voltage balancing. The optimum firing angles are then used to train the GPR and SVM regression models. The GPR and SVM models are finally used as a real-time controller to retrieve the voltage balance in online mode. A simulation model and experimental setup of the electrical power system are built. The modeled system consists of a 500 km long transmission line. The line is divided into three-pi sections to guarantee a real system response. Several simulation and practical case studies have been conducted to test and validate the capability of the proposed integrated approach in solving the voltage unbalance problem. The results have revealed the supreme ability of the proposed integrated approach to restore the voltage balance quickly (within 20 ms) and for a wide range of voltage unbalance factors (VUFs) (3.90–8.42%).

“…Due to their longitudinal structure and characteristics, LPS are prone to face different stability problems. Among the most critical stability concerns are those related to transient and voltage stability [3], including low frequency oscillations (from a small signal stability viewpoint), and voltage collapse. Indeed, sustained low frequency oscillations [13][14][15][16] as well as voltage instability situations [17][18][19] have been reported in several power systems with longitudinal structure.…”

“…LPS are characterized by weak longitudinal structures with radial configuration, long transmission lines, and generation centers electrically remote from load centers [1][2][3]. Consequently, high power transfers over their long transmission lines, as well as highly loaded conditions in generators are typically critical operating conditions of these power systems [33].…”

“…These power systems, also known as longitudinal power systems (LPS), usually have a radial configuration (with multiple infeed), with generation areas electrically distant from concentrated load centers, connected through long transmission lines, which leads to weak connections between those areas [1][2][3]. Examples of LPS are found in Chile, Mexico, Peru, Taiwan, Finland, Israel, Australia, England, and Italy, among others.…”

Active Splitting in Longitudinal Power Systems based on a WAMPC

This paper proposes an active splitting scheme especially suitable for longitudinal power systems (LPS). The proposed scheme is based on a modified out-of-step (OOS) algorithm combined with an angle difference method using synchrophasor measurements. The remedial actions are based on the detection of possible loss of synchronism due to severe disturbances. The scheme was tested on a detailed dynamic model of the Central Interconnected System of Chile, a good example of extreme LPS. Obtained results show that remedial actions taken by the proposed protection scheme are able to avoid the total collapse of the system during critical contingencies.

The paper narrates widespread use of electrical energy by modern civilization has necessitated producing bulk electrical energy economically and efficiently. The Flexible AC Transmission system (FACTS) is a new technology based on power electronics, which offers an opportunity to enhance controllability, stability, and power transfer capability of AC transmission systems. Here SVC has been developed with the combination of TCSC and TCR. The paper contains simulation models of Thyristor controlled Series Capacitor (TCSC) and Thyristor controlled Reactor (TCR)-based Static VAR Compensator (SVC) which are the series and shunt Flexible AC Transmission Systems (FACTS) devices. The fact devices are designed by considering the line losses and their stability. The design and simulations of TCSC and TCR-based SVC shows the effectiveness of result using the MATLAB/Simulink. The designed system will try to reduce the voltage drops and electrical losses in the network without the possibility of transient especially in case of long transmission system. Student feedback indicates that this package is user-friendly and considerably effective for students and researchers to study theory of controlled reactor compensators, series capacitor compensator, and the reactive power control and voltage regulation
