Smart Management Strategies Of Utility-Scale Energy Storage Systems In Power Networks, Choton Kanti Das
Smart Management Strategies Of Utility-Scale Energy Storage Systems In Power Networks, Choton Kanti Das
Theses: Doctorates and Masters
Power systems are presently experiencing a period of rapid change driven by various interrelated issues, e.g., integration of renewables, demand management, power congestion, power quality requirements, and frequency regulation. Although the deployment of Energy Storage Systems (ESSs) has been shown to provide effective solutions to many of these issues, misplacement or non-optimal sizing of these systems can adversely affect network performance. This present research has revealed some novel working strategies for optimal allocation and sizing of utility-scale ESSs to address some important issues of power networks at both distribution and transmission levels. The optimization strategies employed for ESS placement and …

Electrical Engineering Dissertations
Microgrids have proliferated the landscape of the world’s power systems as distributed energy generation, energy storage, and evolving electrical loads become more abundant. Microgrids offer many advantages to the end user of electrical power over traditional power distribution networks that rely on exceedingly large rotating machines producing power for a large group of electrical loads over long physical distances. Microgrids provide a unique benefit to smaller electrical networks that may be isolated, may have unique electrical loads, or may have a network of energy storage devices that can be utilized to serve the microgrid in particular operational scenarios. With the …
Integration And Validation Of Power Hardware-In-The-Loop Generator Models For Deployment In A Distributed Generation Source Testbed, Jacob Sanchez
Integration And Validation Of Power Hardware-In-The-Loop Generator Models For Deployment In A Distributed Generation Source Testbed, Jacob Sanchez
Electrical Engineering Dissertations
Hardware in the Loop (HIL) is an established technology that allows for rapid prototyping of controls and verification of how physical devices respond for valid simulated systems. This involves deploying a model of a system onto a Field Programmable Gate Array (FPGA) that can take in external inputs and outputs the state variables present in the system. An example of this could involve the control of the roll, pitch, and yaw of a plane. A simulated plane could output the current state variables of the plane to an external controller which will respond with control signals to the simulated system …

Detection Of Grid Voltage Anomalies Via Broadband Subspace Decomposition, Samet Biricik, Soydan Redif
Conference papers
Due to the increase of sensitive loads on the mains power grid, measurement and monitoring of the power quality (PQ) have become an important factor for both consumers and operators. As is well-known, PQ problems occur in a very short time period with specific characteristics. In transmission or distribution systems, power quality data are collected from monitoring devices such as digital fault recorders, power quality and dynamic system monitors, etc. The recorded data has to be analysed in order to understand system anomalies. These anomalies may be due to sources of broadband noise. In this study, we employ broadband subspace …

Turkish Journal of Electrical Engineering and Computer Sciences
Along with the rapid advances in power electronics and semiconductor technology, electronic power transformers (EPTs), which are expected to replace conventional power transformers in the future, are being developed and designed. This study presents the dynamic performance of the intelligent controller structure in the control of an EPT. The EPT structure, consisting of the input, isolation, and output stages, is designed for experimental and simulation studies. A three-phase pulse width modulation (PWM) rectifier is used to rectify the grid voltages at the input stage of EPT. The DC-bus voltage of the three-phase PWM rectifier is controlled by a neuro-fuzzy controller …

The prevalent power quality problems in smart microgrids and power distribution systems are voltage sag, voltage swell, and harmonic distortion. The achievement of pure sinusoidal waveform with proper magnitude and phase is currently a great research and development concern. The aim of this paper is to evaluate and mitigate the smart microgrid harmonics, voltage sag, and voltage swell throughout a 24-h cycle, taking into consideration the variation in solar power generation due to changes in irradiation received by photovoltaic cells, the variation in wind power generation due to changes in wind speed, and the variation of linear and nonlinear load …
