Design of a Unified Power Controller for Variable-Speed Fixed-Pitch Wind Energy Conversion System Abstract? A unified power controller for variable-speed fixed-pitch wind energy conversion system (WECS) is designed covering the whole range of wind speed in this paper. The proposed controller is composed of a modified maximum power point tracking (MPPT) controller in low wind…
Design of a Unified Power Controller for Variable-Speed Fixed-Pitch Wind Energy Conversion System Abstract? A unified power controller for variable-speed fixed-pitch wind energy conversion system (WECS) is de-signed covering the whole range of wind speed in this paper. The proposed controller is composed of a modified maxi-mum power point tracking (MPPT) controller in low wind…
Detecting and Locating Faulty Nodes in Smart Grids Based on High Frequency Signal Injection Abstract?An on-line method for detecting and locating a faulty node in the utility grid is proposed for smart grids. The method is based on injection of high frequency (A-Band) current signal into the grid that would impose voltages (less than 1V…
Determining Optimal Buses for Implementing Demand Response as an Effective Congestion Management Method Abstract-Demand response (DR) can be counted as an effective congestion management (CM) method in power systems. However, appointing the optimal buses for the demand response programs (DRPs) implementation is one of the main challenges for the power system operators. In this paper,…
Doubly Fed Induction Generator for Wind Energy Conversion Systems with Integrated Active Filter Capabilities Abstract? deals with the operation of Doubly Fed Induction Generat or (DFIG) with an integrated active filter capabilities using Grid Side Converter (GSC). The main contribution of this work lies in the control of GSC for supplying harmonics in addition to…
Dual-Bridge LLC Resonant Converter With Fixed-Frequency PWM Control for Wide Input Applications Abstract? A dual-bridge (DB) LLC resonant converter for wide input applications. The topology is an integration of a half-bridge (HB) LLC circuit and a full-bridge (FB) LLC circuit. The fixed-frequency pulsewidth-modulated (PWM) control is employed and a range of twice the minimum input…
Dual-Bridge LLC Resonant Converter With Fixed-Frequency PWM Control for Wide Input Applications Abstract– In the first place, proposes a dual-bridge (DB) LLC resonant converter for wide input applications.

In this paper, we investigate dynamic base station (BS) switching to reduce energy consumption in wireless cellular networks. Specifically, < Final Year Projects > we formulate a general energy minimization problem pertaining to BS switching that is…
Dynamic Modeling and Control of Utility Interactive Microgrid Using Fuzzy Logic Controller Abstract? In this paper, dynamic modeling and simulation of microgrid consisting of photovoltaic (PV) system and solid oxide fuel cell (SOFC) system is presented. The microgrid system is considered to be operating in grid connected mode and Hence it is connected to the…
Dynamic Optimal Power Flow for Active Distribution Networks Abstract?Active Network Management is a philosophy for the operation of distribution networks with high penetrations of renewable distributed generation. Technologies such as energy storage and ?exible demand are now beginning to be included in Active Network Management (ANM) schemes. Optimizing the operation of these schemes requires consideration…
Dynamic Query Forms for Database Queries Abstract? Modern scientific databases and web databases maintain large and heterogeneous data. These real-world databases contain hundreds or even thousands of relations and attributes. Traditional predefined query forms are not able to satisfy various ad-hoc queries from users on those databases. This paper proposes DQF, a novel database query…
DYNAMIC STABILITY OF A MICROGRID WITH AN ACTIVE LOAD Abstract?Rectifiers and voltage regulators acting as constant power loads form an important part of a microgrid?s total load. In simplified form, they present a negative incremental resistance and beyond that, they have control loop dynamics in a similar frequency range to the inverters that may supply…
