In this paper, phasor measurement unit (PMU) data-based synchronous generator model identification is carried out using unscented Kalman filter (UKF). The identification not only gives the model of a synchronous generator’s swing dynamics, but also gives its turbine-governor model along with the primary and secondary frequency control block models. PMU measurements of active power and voltage m...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...

Statistical system identification and its use for the optimal control of thermal power plants are discussed. The analysis of the plant dynamics and derivation of the state-space representation are performed by fitting a multivariate AR model to the plant data obtained by an experiment. The basic concept of the power plant control and the motivation that necessitated the statistical approach are...

Abstract— In this paper, power system modes are monitored for the purpose of stability prediction using an innovated recursive Subspace System Identification (SSI) method. SSI methods can process large package of sampled data using powerful mathematical tools. However, their application for monitoring requires some changes in SSI algorithms in order to provide their recursive versions. SSI algo...

During major power system disturbances, when multiple component outages occur in rapid succession, it becomes crucial to quickly identify the transmission interconnections that have limited transfer capability. Understanding impact of an outage on these critical (called saturated cut-sets) is important for enhancing situational awareness and taking correct actions. This paper proposes a new gra...

This research paper proposes a methodology to apply identification methods find simplified model of three different governors in single area electric power system (SAEPS). A SAEPS with governors-turbine is presented: hydraulic turbine, steam turbine and reheat turbine. In this same investigation, an analytic reduction has been performed, fifth order was found analytically, thus transfer functio...
