Strategic Placement and Sizing of Unified Power Flow Controller using Multiple Indices and Flower pollination Algorithm for Contingency Management of Deregulated Power Systems | Chapter 2 | Research and Developments in Engineering Research Vol. 8

 In the scenario, the demand for energetic power is increasing that initiates the need to increase capacity generation. However in view of the restricted Resources available it is necessary to develop efficient plans with less cost. Optimal reallocation of dynamo and implementation of FACTS devices have happened found expected very effective in this regard. In this paper, a approach of optimal bringing into harmony of generators using Flower impregnation of the ovum algorithm in the attendance of UPFC for contingency management has happened proposed. The UPFC has existed placed on the basis of an index that is a combination of L-index and LUF index. A multi objective function has existed chosen for tuning the alternator. The multi-objective function consists of potential deviation, active capacity generation cost and broadcast line loss.  The proposed system has been proven and implemented on an IEEE 30 bus method for n-1 contingency condition. The p FPA on IEEE 30 transport system without UPFC and accompanying UPFC are compared. Similar reasoning has been done outside and with possibility conditions.

An Innovative Fuzzy Rule Based Control Analysis of Advanced Unified Power Flow Controller | Chapter 9 | New Approaches in Engineering Research Vol. 1

 The rapid development of high power semiconductor devices with fast control features has enabled more efficient and effective power flow control. This category's Flexible AC Transmission Systems (FACTS) introduces several novel operating control devices. The Advanced Unified Power Flow Controller (AUPFC), also known as multi-converter UPFC or Generalized-UPFC, is a recent device that can control the bus voltage and power flows, both real and reactive, of multiple lines or even a sub-network. This chapter describes a novel real-time approach for analyzing the Advanced Unified Power Flow Controller. Based on the analysis, a new fuzzy logic rules-based controller that improves system performance has been proposed. The controller rules are built around the relationship between the series inserted voltages in multi-line and the desired changes in real/reactive power flows in the power system. The effects of various controllers, as well as the parameters of series transformers and transmission lines, were investigated using SIMULINK control block models. A case study demonstrates the effectiveness of the proposed scheme.

Coordination of PSS and Facts Devices for Power System Stability Enhancement: A Comprehensive Review | Chapter 3 | Advanced Aspects of Engineering Research Vol. 8

 Power system stability has been and will continue to be a key challenge in power system operations due to power system oscillations caused by complicated interconnections.

Efforts have been made to dampen power system oscillations in order to improve power system stability. The instability caused by complex linkages is known as small signal stability. With power system stabilisers, small signal stability can be reduced (PSS). PSS, on the other hand, has several drawbacks, such as substantial voltage profile changes and the potential for leading power factor operations, both of which can degrade system stability in the face of severe disturbances. Traditional PSS may not be enough to attenuate inter-area oscillations and the influence of voltage profile fluctuation in large multi-machine power systems. Flexible Alternating Current Transmission System (FACTS) power electronic systems, on the other hand, are good at dampening inter-area oscillations and can tolerate voltage changes. As a result, this research provides a complete analysis and assessment of PSS and FACTS power oscillation damping (POD) controllers in minimising low frequency oscillations using computational intelligence methodologies. It is emphasised the necessity of technical paper publishing on PSS and FACTS-based controller design, optimum location, and parameter tuning. Finally, some future research directions for innovative PSS and FACTS devices are suggested as a resource for researchers.
