Ac Transmission

Power engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. Flexible AC Transmission system (FACTS) controllers can balance the power flow and thereby use the existing power system network most efficiently. Because of their fast response, FACTS controllers can also improve the stability of an electrical power system by helping critically disturbed generators to give away the excess energy gained through the acceleration during fault. Thyristor controlled series compensator (TCSC) is an important device in FACTS family, and is widely recognized as an effective and economical means to solve the power system stability problem. TCSC is used as series compensator in transmission system. In the present work a TCSC controller is designed and tested over a single machine infinite bus (SMIB) as well as a multi-machine power system. Detailed simulation studies are carried out with MATLAB/SIMULINK environment and the effect of the TCSC parameter variations over the system stability is studied.

The Stability

The Flexible Alternating Current Transmission Systems (FACTS) device deals with the control of power flow, alternating current of transmission line and immediately respond towards the stability problems of the system. The present paper show that how the FACTS devices enhance the different parameter of the power systems like power transfer capacity of line, system stability etc. In MATLAB a simplified transmission system is modeled and the resultant power (PQ) and voltage profiles are studied as an uncompensated system. Now the same transmission system is simulating with FACTS device i.e. Static Synchronous Series Compensator (SSSC), Fixed Capacitor Thyristor Controlled Reactor (FC-TCR) and Static Synchronous Compensator (STATCOM). The result obtained after simulation provide the power and voltage profiles, are analyzed as a compensated system. Finally we found that a compensated system have better voltage profile and power flow w.r.t. an uncompensated system.

Flexible Alternating Current Transmission

Due to increasing power demand in a deregulated power system, the stability of the power system may get affected and sometimes it may also cause congestion in the transmission lines of power networks. It is a major issue for a deregulated power system and its management provides a competition environment to different market players. In this paper, market split based approach is used to tackle the problem of congestion which split the system into zones. Locational Marginal Pricing (LMP) method is used to access the prices at different buses. The objective is to minimize the congestion effect. DC optimal power flow based system is used to solve such type of problem. TCSC (Thyristor-Controlled Series Compensation), FACTS (Flexible Alternating Current Transmission System) device is used to reduce the losses in a transmission system. Market splitting based approach is effective to manage the prices at different buses and system stability is increased by using TCSC. The whole work is carried out on IEEE 14 bus system.

System Stabilizer

Power System Stabilizer (PSS) is one of the most used controllers in the local generations, primarily it aimed to suppress local mode of oscillations. On the other hand, the Unified Power Flow Controllers (UPFC) the most versatile member of flexible alternating current transmission system devices to simultaneously control real and reactive power flows on transmission lines, as well as regulate selected bus voltage. Each of these controllers, on their own, can show satisfactory performance to enhance power system stability. However, when they utilized together, their dynamic performance can degrade due to controller interaction, that should be strategically optimized. In this paper, the coordinated design of pss's and upfc is realized to damp inter-area oscillations in  two-area power system using particle swarm optimization (PSO) method. The simulated cases in Matlab environment show that the interaction of pss's and upfc can be optimized, so the inter-area oscillations can be effectively mitigated following after fault, the simulation results of the uncoordinated design are also presented.

Power Flow Controller

The equipments based on the power electronics have been improved under the name of Flexible Alternating Current Transmission Systems (FACTS) in the last years. Unified Power Flow Controller (UPFC) is the most widely used FACTS device to control the power flow and to optimize the system stability in the transmission line. UPFC is a FACTS devices that can control active and reactive power flow in transmission line by means of injection controllable series voltage to the transmission line. This paper proposes a new connection for a Unified Power Flow Controller (UPFC) to control the active and reactive power flow control in two sides of a transmission line independently and it regulates bus voltage in the same transmission line, furthermore it is possible to balance line current too. This connection of the UPFC will be called an center node UPFC (C_UPFC). It is one of the newest devices within the FACTS technology. The structure and capability of the C_UPFC is discussed and its control scheme is based on the d-q orthogonal coordinates. According to this, the performance of UPFC for several modes of operations using different control mechanisms based on Proportional-Integral (PI) and PID based controllers has been studied. The obtained simulation results from Matlab/simulink confirm the effective features.
