Control-oriented model of a generating set comprising a diesel engine and a synchronous generator
Tuffaha, Mutaz; Gravdahl, Jan Tommy (Peer reviewed; Journal article, 2015)A generating set (Genset) comprises a prime mover such as a Diesel Engine, and a synchronous generator. The most important controllers of such systems are the speed governor to regulate the engine or shaft speed and the ... -
Mixed-Integer Formulation of Unit Commitment problem for power systems: Focus on start-up cost
Tuffaha, Mutaz; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2013)In this work, the Mixed-Integer (MIP) formulation for unit commitment problem (UC) for power systems is discussed. A new formulation for the start-up cost is suggested as well. This new formulation of the start-up cost ... -
Mixed-Integer Minimization of the Cost function of the Unit Commitment problem for Isolated power systems
Tuffaha, Mutaz; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2013)Unit Commitment (UC) is a minimization problem that aims to schedule the required generating units in a power system over some time horizon to meet the demand based on minimizing the production cost. In this paper, we ... -
Modeling and Control of a Marine Diesel Engine driving a Synchronous machine and a Propeller
Tuffaha, Mutaz; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2014)In some designs of power systems for marine vessels, large-size or medium-size Diesel engine(s) is(are) used to drive one synchronous machine to generate electricity, and the main propeller, simultaneously, through a gear ... -
Modeling movement-induced errors in AC electromagnetic trackers
Tuffaha, Mutaz; Stavdahl, Øyvind; Stensdotter, Ann-Katrin (Peer reviewed; Journal article, 2020)Error analysis of electromagnetic motion tracking systems is of growing interest to many researchers. Under sensor movement, it is logical to presume that the error in position and orientation measurements will increase. ... -
On the Management and Control of Isolated Power Systems
Tuffaha, Mutaz (Doctoral thesis at NTNU;2015:261, Doctoral thesis, 2015)Power systems have been a rich arena for research and study since the very beginning of their use commercially in the late 19th century. At the beginning, the objectives of the research were focused on the stability and ...
