Damping of vibrations in the power system using fuzzy control strategies Engineering essay
Fuzzy logic acts as a powerful tool to address these uncertainties. 8. This paper presents a fuzzy logic-based control strategy for STATCOM to improve power system stability and performance. Abstract This paper proposed an optimal fuzzy controller for power system oscillation damping in a multi-machine environment. In this strategy, the proposed controller is optimized by a novel chaotic invasive weed optimization algorithm. Moreover, a new objective function has been considered to test the proposed controller in different ways. The well-developed unified power flow controller UPFC has demonstrated its ability in providing voltage support and improving power system stability. The purpose of this article is to demonstrate the ability of the UPFC in reducing oscillations in an integrated energy system of a wind farm using eigenvalue analysis, article Li2014DampingCS, title, Damping control strategies of inter-area low-frequency oscillation for DFIG-based wind farms integrated into an energy system author Hui Li and Shengquan Liu and Haiting Ji and Dong Yang and Chao Yang and Hong-lan Chen and Bin Zhao and Yaogang Hu and Zhe Chen, magazine International, The low-frequency oscillations are related to the small signal stability of the power system and are detrimental to the objectives of maximum power transfer and stability of the power system. Problems due to. The sample test system, adapted from the first IEEE benchmark model for SSR to replace the synchronous generator, is used to aggregate a wind farm-based self-excited induction generator. Therefore, it investigates the SSR phenomena and the oscillation of the damping power system while integrating a large wind farm based on SEIG.1. Introduction. The continuous increase in the capacity of thermal power units and the scale of electricity networks can lead to more serious effects of low-frequency oscillations on the safety and stability of power systems. 1. Accidents have occurred related to low frequency oscillations due to insufficient damping. China. The escalating demand for energy and the increasing environmental consequences of fossil fuel use necessitate a paradigm shift towards the integration of renewable energy sources (RES) as the core of the electric power sector. Solar photovoltaic SPV and wind-based generation have emerged as the most promising and feasible solutions. Many literary works highlight approaches based on Typelogic theory to design intelligent power system stabilizers for damping slower types of oscillation 20, 23. Typelogic has been implemented to control a TCSC device to provide additional damping to the power system oscillations 24, 25.

Many researchers have carried out their research work on PSS with SMIB and higher order systems under fault conditions. The proposed RNNPSS has faster convergence than feed-forward neural network and LQR stabilizer for multi-machine systems 1. Small signal stability cannot be improved for inter-regional network attenuation. The device increases power transfer and improves performance,
