Book excerpt: Unified Power Flow Controller (UPFC) is the most widely used Flexible ac Transmission system ( FACTS ) device to control the power flow and to optimize the system stability in the transmission line. It should be installed to control the voltage, as well as to control the active and reactive power flow through the transmission line. This project is using PSCAD/EMTDC and MATLAB software to model and to verify the UPFC system in order to improve its performance in power system. MATPOWER in MATLAB software used to run the power flow of IEEE 9 bus power system network. Then, by using PSCAD/EMTDC software, IEEE 9 bus system was designed and the result of power flow 9 bus system using PSCAD/EMTDC was compared with the power flow in MATPOWER. The result of active power, P (MW) , reactive power ,Q (MVar) and power loss were compared to make sure that both software have the similar answer with only 1% difference. The power flow in both softwares must be similar before injecting the UPFC system. Then, the active power and reactive power performance will be improved due to injecting the UPFC device. Stability and transient performance of active and reactive power was analyzed.

Book Testing Statcom Model in IEEE Power System Network Using PSCAD Software

Download or read book Testing Statcom Model in IEEE Power System Network Using PSCAD Software written by Mohd Firdaus Daud and published by . This book was released on 2008 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any transmission system, the ultimate goals are to transmit power with high quality, economical and low risk of system failure. The ever increasing of power demands and loads especially non-linear loads making the power system network become complex to operate and the system becomes insecure with large power flows without adequate control. One way to introduce power system control is by applying controller known as FACTS (Flexible AC Transmission System) controllers. STATCOM (Static Synchronous Compensator) is one of the FACTS controllers and can be introduced to the power system to regulate terminal voltage and to improve system's stability. By using IEEE 4 bus power system network, the effectiveness of STATCOM is tested by applying the controller at the critical location of the power system. The critical location of a power system is determined by the voltage drop that falls below 0.95 or above 1.05. Using PSCAD/EMTDC simulation software, the simulations of STATCOM in IEEE 4 bus power system networks can be realized. To verify the PSCAD/EMTDC simulation results, load flow analysis are acquired using MATLAB software through Hadi Saadat's load flow analysis method. With these softwares, both systems' power flow can be compared to determine the effectiveness of STATCOM in the power transmission system.

Book Modeling and Control of the Hybrid Power Flow Controller for Steady state and Dynamic Studies and Applications

Download or read book Modeling and Control of the Hybrid Power Flow Controller for Steady state and Dynamic Studies and Applications written by Behnam Tamimi and published by . This book was released on 2017 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexible ac transmission system (FACTS) controllers offer new opportunities to better control power systems, and can address some of the critical challenges faced by the grid, especially in the context of smart grids. Furthermore, the smartening of distribution systems with distributed generation, storage devices, and intelligent loads have created challenges for the operation of distribution feeders, which can be addressed adequately with power-electronics based controllers and FACTS controllers for distribution systems. However, the capital intensive nature of these controllers is a major obstacle for a wide application of this technology in power systems. A cost effective FACTS controller has been introduced in the literature, which yields operating characteristics similar to those of the versatile Unified Power Flow Controller (UPFC). This device consists of converters as well as passive components, and is referred to as the Hybrid Power Flow Controller (HPFC). The study of the HPFC and its performance in electric power systems requires adequate and relevant models representing the device behavior according to the intended studies, such as steady state or time-domain dynamic analyses; moreover, the benefits of an HPFC are determined by its limits and operating constraints. Therefore, static and dynamic models of the HPFC for transmission and distribution system applications are proposed and studied in this work. First, steady-state models of the HPFC for power flow and optimal power flow (OPF) studies are proposed in this work, considering its multiple control modes and operating constraints. Thus, a strategy for control limit handling in power flow calculations is proposed, while considering a discrete passive shunt capacitor bank in the device. Moreover, an OPF model of the device is proposed and explained in detail, representing all the device control and physical limits as constraints in the mathematical formulation, so that the HPFC can be optimally dispatched as a part of the transmission system control assets; this model is used to determine the optimal ratings of the device based on a cost--benefit analysis. The proposed power flow and OPF models are tested and validated based on several loadability studies on a two-area benchmark test system. The HPFC power flow model is also tested and applied to a detailed model of Ontario grid and its neighboring networks with more than 6000 buses. The analyses demonstrate the application of the models for planning and operation studies, evaluating the performance and the effectiveness of the device based on realistic studies and scenarios. Second, the merits and the added value of the HPFC application to distribution systems are discussed here through detailed modeling and time-domain simulations, examining its impact on a distribution network under different conditions. Thus, a detailed dynamic representation of the HPFC is developed and implemented in PSCAD/EMTDC, describing and proposing control strategies to properly operate this controller in distribution system applications, such as an effective and simple procedure for starting-up the device. The developed model is used to demonstrate the effectiveness of the controller for solving problems in distribution systems, such as voltage sags associated with feeder faults and power flow fluctuations due to intermittent renewable generation using a benchmark network as an illustrative example.

Book Study the Power Flow Control of a Power System with Unified Power Flow Controller

Download or read book Study the Power Flow Control of a Power System with Unified Power Flow Controller written by Vakula Peesari and published by . This book was released on 2010 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical power systems is a large interconnected network that requires a careful design to maintain the system with continuous power flow operation without any limitations. Flexible Alternating Current Transmission System (FACTS) is an application of a power electronics device to control the power flow and to improve the system stability of a power system. Unified Power Flow Controller (UPFC) is a versatile device in the FACTS family of controllers which has the ability to simultaneously control all the transmission parameters of power systems i.e. voltage, impedance and phase angle which determines the power flow of a transmission line. This project proposes a case study to control the power flow of a power system with UPFC. In this study, I am considering a standard 5-bus network for the analysis. Power flow equations are solved using Newton Raphson's algorithm and the simulations of the algorithm are done in MATLAB. The results of the network with and without UPFC are compared in terms of active and reactive power flow in the transmission line at the bus to analyze the performance of UPFC.

Book Design and Simulation of Unified Power Flow Controller with Grid Storage

Download or read book Design and Simulation of Unified Power Flow Controller with Grid Storage written by Christopher Beaudoin and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power flow between two transmission systems across an uncontrolled interface can be problematic if there is unequal sharing between the tie lines. System configuration changes such as generation dispatch, or out of service elements can cause thermal overloads. In addition, some weaker areas of the system which may have insufficient transmission can have difficultly supporting the voltage at buses with high loading particularly after the loss of one element. This thesis presents a real transmission system which has two problems: a thermal limitation caused by unequal tie-sharing across an uncontrolled interface, and a post-fault voltage stability concern. Various potential solutions are analyzed and shown to address one or the other of these two problems; none of which were capable of solving both. A Unified Power Flow Controller (UPFC) is proposed which can effectively address both problems and can provide additional benefit in the form of a grid storage interface. The operational characteristics of a UPFC are analyzed and used to develop an electrical model and control system topology. The model with its control system is implemented in PSCAD. The UPFC is proven to be capable of effectively addressing the thermal limitation and voltage stability issues of the system. Further, a battery is added to the UPFC to provide grid energy storage. Cost saving measures through controller design are also proposed and implemented. This work demonstrates that a UPFC can be an effective solution to typical problems (such as thermal and voltage constraints) faced by a transmission system. A UPFC with grid storage can also provide an alternative to building costly transmission lines or generation by enhancing reliability, reducing demand on generation cause by system peaks, smoothing intermittent generation, etc.
