In modern power systems, condition based monitoring and diagnosis is essential to ensure the effective reliable operation of different high voltage equipment (HVE). Compared other techniques, partial discharges (PD) measurement considered as a key method for assessing insulation health condition. The benefits PD HVE can be extended by proper detection, identification, interpretation signal. Among both online offline very promising technique that assists in robust system which reduces failure...
Microgrids are the future version of advanced distribution networks due to fast growth renewable energy resources near consumers' side. The microgrids operated in on-grid mode (OGM) with utility grid, and isolation (IM) without grid. This dual operational causes protection control challenges microgrids. research paper suggests an hardware-supported fault detection, phase identification & localization method for AC scheme deploys a Discrete Kalman Filter (DKF) state estimation voltage current...
Load scheduling and peak demand shaving are two critical aspects of the utility grid operation that help both operators as well end-users. This paper proposes a two-stage community home energy management system for microgrids. The first stage deals with dynamic clustered load scheme. Comparatively flatter power was attained using particle swarm optimization (PSO) incorporating user-defined constraints. new arising or remaining peaks consequence consumer constraints catered to in second...
Abstract In modern distribution networks, integration of distributed generations (DGs) at consumer premises is common. However, islanding detection in such a grid‐tied generation (GTDG) network the topmost challenge to ensure power quality and reliable operation. This paper presents modified passive scheme (MPIDS) for GTDG network, using One‐D recursive Median filter (ODRMF) algorithm. Firstly, point common coupling (PCC), 3‐phase voltage acquired. Next, ODRMF employed extract 3rd harmonic...
In this letter, a new sliding-mode-sensorless control algorithm is proposed for the field-oriented induction machine drive. algorithm, terms containing flux, speed, and rotor time constant, which are common in both current flux equations, model of estimated by sliding function. The speed estimation accuracy guaranteed when error between actual observed converges to zero. Hence, fourth-order system reduced two second-order systems, becomes very simple robust parameter uncertainties. approach...
A new closed loop current model flux observer is designed to estimate the rotor flux, position and velocity of an induction machine. The includes carefully sliding mode functions which are derivative fluxes along /spl alpha/ beta/ axes. Therefore, when estimated converges measured one, estimation a mere integration function. speed can then be derived from flux. In observers all terms that contain time constant have been replaced by functions, thus making proposed estimations completely...
This paper presents two battery energy management (BEM) techniques for an electric vehicle (EV) traction system which incorporates indirect field-oriented (IFO) induction motor (IM) drive system. The main objective of the proposed BEM is to regulate IM's speed while minimizing lithium-ion (Li-ion) bank state charge (SOC) reduction and health (SOH) degradation. In contrast most existing work, operate without any prior knowledge driving profiles or road information. first technique cascaded...

Accurate flux estimation is core any opted technique all types AEV systems. Therefore, an accurate closed-loop voltage model estimator that...
The main contribution of this paper is the integration a battery management system (BMS) to ensure safe operation and automated swapping for an electric scooter (e-scooter). BMS constantly monitors state charge (SOC) temperature, initiates under predefined conditions. This crucial because conventional sometimes fails detect early signs potential issues, leading safety hazards if not addressed promptly. Battery stations are effective solution, offering alternative traditional charging by...
