“…Besides, an increase in active and reactive power between the buses and lines, and at the same time, voltage stabilization in the Main and Lake Buses in this SVC-HVDC model were obtained. However, this paper examined a comprehensive model for the simultaneous effects of all the two types of devices for power flow and controlled the active and reactive power simultaneously, which had not been done in any of the previous studies [9], [23]- [25], [29]- [31], [33], [34], [40], [52], [54], [57], [68]- [70].…”

“…SVC has been used to optimize the Newton-Raphson power flow modeling [29], [30]. In [31], a control method for the coordination of HVDC and FACTS was proposed with the aim of obtaining small signal stability of the power system, which indicated that by changing the parameters, the oscillation between adjacent areas for production was reduced. In [32], a multiple optimal power flow (OPF) solution method was presented with the presence of FACTS devices, which were very powerful and fine-tuned the unequal constraints of the system.…”

Transmission lines react to an unexpected increase in power, and if these power changes are not controlled, some lines will become overloaded on certain routes. Flexible alternating current transmission system (FACTS) devices can change the voltage range and phase angle and thus control the power flow. This paper presents suitable mathematical modeling of FACTS devices including static var compensator (SVC) as a parallel compensator and high voltage direct current (HVDC) bonding. A comprehensive modeling of SVC and HVDC bonding in the form of simultaneous applications for power flow is also performed, and the effects of compensations are compared. The comprehensive model obtained was implemented on the 5-bus test system in MATLAB software using the Newton-Raphson method, revealed that generators have to produce more power. Also, the addition of these devices stabilizes the voltage and controls active and reactive power in the network.

“…In [16], the ability to improve the voltage stability of two FACTS devices such as SVC and static synchronous compensator(STATCOM) has been compared. In [17] and [18], using two static synchronous series compensator (SSSC) and current source converter (CSC) devices, he improved the static stability of the voltage in the network. This reference has provided a mathematical model of the voltage dependence of SSSC and CSC devices.…”

Due to the high cost of investment for the development of the transmission network and the key role of transmission networks in the restructured environment, the use of FACTS devices is considered a key issue. In this paper, two issues of location and optimal capacity of TCSC in transmission networks has been investigated. In the proposed method, the objective function is defined in order to reduce losses and increase network load ability. This problem was studied in two technical and economic approaches and its results were presented. For this purpose, first, the problem of locating in peak load conditions of the network was done separately and then simultaneously in the technical approach. Next, in the economic approach, the cost of installing the equipment in question was also included in the optimization problem. In this approach, the profit from installing TCSC is considered as the objective function of the problem and the best place and capacity of the equipment was determined in order to achieve the maximum amount of profit. Average models available in the references have been used to model FACTS devices. Also, due to the contingency in the network, the improvement of the maximum load ability of the network lines under the outages conditions of the line and generator has been discussed. In order to two-objective optimization in the technical approach, the genetic algorithm based on the Pareto front and the multi-objective HSA has been used. This algorithm has a good speed in the convergence of large nonlinear problems. Also, a comprehensive and new model with the combination of TCSC-high-voltage direct current (HVDC)-static VAR compensators (SVC) has been introduced and the intended simulation has been performed. Finally, with the help of a new meta-heuristic algorithm, the topic of optimal power flow in the presence of these devices has been comprehensively presented and the results have been compared with similar methods. The results of numerical studies show that FACTS devices can have a significant effect in reducing losses and increasing network load ability.Also, the type of equipment used has a great impact on the outcome of the problem. As it is clear from the results of the simulations, in the technical approach, in order to achieve the lowest amount of losses in the IEEE 30-buses network by installing the equipment, TCSC should be installed in line number 15 between buses 4 and 12. The best amount of reactance compensation of this line was about 79.90% of the line reactance, as a result of which the network power loss was reduced by about 4.17%. Also, in the continuation of the simulations, the best place and capacity to install TCSC in the network was determined in order to improve the network load ability. As a result of this simulation, the best location of line 36 between buses 27 and 28 was determined, and the best amount of reactance compensationThe associate editor coordinating the review of this manuscript and approving it for publication was Ahmed F. Zobaa .

“…In fact, it is highly helpful when working with MIMO models, which can simultaneously satisfy a number of control objectives. However, it has certain downsides, including the requirement for adequate mathematical proficiency and the likelihood that it is unfeasible for large-scale systems [22], [23].…”

The focus in this study is on an islanded microgrid based on hybrid renewable energy sources and storage systems. This latter is considered as an essential element for all off-grid autonomous systems to offer a reliable and stable operation. The proposed system is composed of a photovoltaic system, a wind power system based on a synchronous generator and a storage system. The proposed control strategy is intended to control, through the load side converter (LSC), the AC bus voltage in terms of amplitude and frequency under different operating conditions, and to obtain, through the bi-directional battery side converter (BSC), a better regulation between the available production and the global load demand. The proposed strategy also contributes to the power quality improvement in the AC bus by controlling the PV inverter to work as a shunt active power filter to provide the required harmonic current component to non-linear loads. A new robust control strategy for internal current and voltage control loops is proposed in this research paper, it’s the active disturbance rejection control (ADRC) and it is based on the extended state observer which allows to estimate all disturbances affecting the control, such as modeling errors and parameter variations.
