This document describes a single-phase grid-connected fuel cell system that uses a boost-inverter topology for low cost and compactness. It incorporates battery-based energy storage and a bidirectional dc-dc converter to support the slow dynamics of the fuel cell. The boost inverter is voltage-mode controlled while the bidirectional converter is current-mode controlled to minimize current ripples drawn from the fuel cell. It can operate in both grid-connected and stand-alone modes, with the boost inverter controlling active and reactive power using an algorithm based on a second-order generalized integrator.

This document discusses a study focused on integrating and operating a single-phase bidirectional inverter with two buck/boost maximum power point trackers for DC distribution applications. The inverter controls power flow between the DC bus and AC grid and regulates the DC bus voltage. A droop regulation mechanism is proposed to reduce capacitor size, balance power flow, and accommodate load variation based on inverter inductor current levels. The buck/boost MPPT topology allows operation at the 380V DC bus voltage from 0-600V PV array voltages, reducing voltage stress on the inverter. The controller can check MPPT input configuration, distribute current equally between two parallel MPPTs, and smooth mode transitions. Experimental results from a 5kW system

The document proposes a new control method for a three-level inverter that allows the DC-link voltages to be regulated asymmetrically. This would allow photovoltaic modules to be split into two groups, with each group connected to a separate DC-link capacitor, enabling separate maximum power point tracking for each group. The method was tested experimentally using a T-type three-level inverter with each DC-link capacitor supplied by a PV simulator emulating two PV modules under different shading conditions.

This document proposes a novel high step-up converter for photovoltaic systems that uses a voltage multiplier module to achieve high voltage gain without extreme duty ratios. The voltage multiplier module combines a conventional boost converter with coupled inductors. An extra boost converter in the first phase achieves even higher voltage conversion. Using two phases reduces current stress and input current ripple, decreasing MOSFET conduction losses. The proposed converter also functions as an active clamp to reduce voltage spikes across switches, allowing use of lower-rated MOSFETs. A prototype with 40V input, 380V output, and 1000W output demonstrated 96.8% highest efficiency.

In this paper, a topology using a Dual-stator Winding Induction Generator (DWIG) and a boost converter is proposed for the variable speed wind power application. At low rotor speeds, the generator saturation limits the voltage of the DWIG. Using a boost converter, higher DC voltage can be produced while the DWIG operates at Maximum Power Point Tracking (MPPT) even at low speed and low voltage conditions. Semiconductor Excitation Controller (SEC) of the DWIG utilizes Control-Winding Voltage Oriented Control (CWVOC) method to adjust the voltage, considering V/f characteristics. For the proposed topology, the SEC capacity and the excitation capacitor is optimized by analyzing the SEC reactive current considering wind turbine power-speed curve, V/f strategy, and the generator parameters. The method shows that the per-unit capacity of the SEC can be limited to the inverse of DWIG magnetizing reactance per-unit value. The topology is simulated in MATLAB/Simulink platform and experimented with a scaled 1 kW prototype. Both simulation and experimental results demonstrate wide variable speed operation range of the DWIG and verify the optimization.

This document proposes a proxy-based approach to continuous location-based spatial queries in mobile environments. The proxy creates estimated valid regions (EVRs) for mobile clients to reduce the number of queries submitted and load on the servers. For nearest-neighbor queries, the proxy uses two new algorithms to accelerate the growth of EVRs, allowing it to build effective EVRs even with small cache sizes. For window queries, the proxy represents EVRs as estimated window vectors to achieve larger valid regions. Separate index structures (EVR-tree and grid index) are used for nearest-neighbor and window queries respectively, and results from one type of query help improve the other. Experiments show the proposed approach significantly outperforms existing

Single phase grid connected fuel system based on boost inverter
Abstract—
In this project, the boost-inverter topology is used as a building block for a single-phase grid-connected fuel cell (FC) system offering low cost and compactness. In addition, the pro- posed system incorporates battery-based energy storage and a dc–dc bidirectional converter to support the slow dynamics of the FC. The single-phase boost inverter is voltage-mode controlled and the dc–dc bidirectional converter is current-mode controlled. The low-frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the FC itself. Moreover, this system can operate either in a grid-connected or stand-alone mode. In the grid-connected mode, the boost inverter is able to control the active (P) and reactive (Q) powers using an algorithm based on a second-order generalized integrator which provides a fast signal conditioning for single-phase systems. Design guidelines, simulation, and experimental results taken from a laboratory prototype are presented to confirm the performance of the proposed system.

Journal paper a flexible control
This document describes a flexible control strategy using a continuous mixed p-norm (CMPN) algorithm-based adaptive control to enhance the low voltage ride through (LVRT) capability of grid-connected photovoltaic (PV) power plants. PV arrays are connected through a DC-DC boost converter for maximum power point tracking, a DC-link capacitor, grid-side inverter, and transformer. The CMPN algorithm adaptively updates PI controller gains in real-time to control the power electronics during faults and improve the LVRT capability without needing tuning. The effectiveness of this control strategy is evaluated using MATLAB/SIMULINK by subjecting the system to different faults on the IEEE 39-bus test system.
Analysis of a High Efficiency Boost-Inverter with Back-up Battery Storage in ...
paper, proposes an analysis and design of a high efficiency boost-inverter with bidirectional back-up battery storage in fuel cell. When low-voltage unregulated fuel cell (FC) output is conditioned to generate AC power, two stages are required: a boost stage and an inversion one. In this paper, the boost-inverter topology that achieves both boosting and inversion functions in a single-stage is used to develop an FC-based energy system which offers high conversion efficiency, low-cost and compactness. The proposed system incorporates additional battery-based energy storage and a DC-DC bi-directional converter to support instantaneous load changes. The output voltage of the boost-inverter is voltage-mode controlled and the DC-DC bidirectional converter is current-mode controlled. The load low frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the FC itself. Analysis, simulation results are presented to confirm the operational performance of the proposed system.

IRJET- Positive Luo Converter Fed BLDC Motor Driven DPPO Control MPPT for Sol...
This document describes a proposed system using a positive Luo converter to maximize power extraction from a solar photovoltaic array and feed a brushless DC motor. A direct power perturb and observe algorithm is used for maximum power point tracking from the solar array. The positive Luo converter operates in discontinuous conduction mode and provides a 3-phase supply to a voltage source inverter that drives the brushless DC motor. The system aims to improve efficiency by eliminating current sensors, using fundamental frequency switching of the inverter, and providing speed control of the motor without additional control circuits. Simulation results using MATLAB/Simulink are presented to validate the performance of the proposed system under different operating conditions.
Power Quality Improvement in a Grid connected pv system
In this case, the network voltage has the symmetric voltage
sag and voltage swell with 30% of the voltage drop from
0.51 to 0.54 and 30% of the voltage swell from 0.54 to 0.57.
Fig. 9 shows the simulation results for symmetric Voltage
sag and voltage swell. To show the better performance of
the proposed method, the voltage difference between the
desired voltage, network voltage, and load voltage has been
investigated. In Fig. 10, the results of the proposed controller
method and the PWM switching method are compared to
prove the ef ciency of the proposed controller method.
STATCOM compensates for symmetrical voltage swell and
voltage sag with the PWM switching method, but the steady-
state voltage difference is greater than STATCOM with the
proposed control.

The PPC system partially converts power from the PV array to the DC bus when needed, improving efficiency over a full power conversion system. Simulation results show the system can achieve MPPT of the PV and high-voltage ride-through capability for the grid-tied inverter through voltage modulation at the auxiliary PV port.

Reduction of single DC bus capacitance in photovoltaic cascaded multilevel co...International Journal of Power Electronics and Drive Systems
This paper presented single DC bus single phase seven level cascaded H-bridge (CHB) inverter for multi-panel photovoltaic grid-connected applications. A single DC bus supplying flyback converters to produce DC link voltages for CHB cells is suggested. A balanced operation of CHB inverter cells is obtained irrespective to power unbalance occurred by individual maximum power point tracking boost converter of photovoltaic (PV) panels due to the non-uniform irradiation and partial shading. A DC bus voltage control system with addition of estimated DC bus ripple voltage to the reference is proposed to eliminate the second order harmonic contained in the feedback voltage of DC bus enabling to design high bandwidth of DC voltage control loop. This produces fast dynamic response, low total harmonic distortion (THD) of grid current and smaller DC bus capacitance. Mathematical modeling of bus voltage control system is presented. PSIM simulation program is used and the simulation results are obtained to validate the proposed control system.Enhancement of Power System Dynamics Using a Novel Series Compensation Scheme
Phase imbalanced capacitive compensation is a “hybrid” series compensation scheme, where the
series capacitive compensation in one phase is created using a single-phase TCSC in series with a fixed capacitor
(Cc), and the other two phases are compensated by fixed series capacitors (C). The TCSC control is initially set
such that its equivalent compensations at the power frequency combined with the fixed capacitor yield a
resultant compensation equal to the other two phases. Thus, the phase balance is maintained at the power
frequency while at any other frequency, a phase imbalance is created. The effectiveness of the scheme in damping
power system oscillations for various network conditions, namely different system faults and tie-line power flows is
evaluated using the MATLAB/SIMULINK Software

Cloudsim t-drive enhancing driving directions with taxi drivers’ intelligence
This paper presents a smart driving direction system that leverages taxi drivers' intelligence and experience. GPS-equipped taxis act as mobile sensors to model the dynamic traffic patterns of a city. A time-dependent landmark graph models traffic patterns and experienced drivers' route choices to provide users with the practically fastest route to a destination at a given departure time. A clustering approach estimates travel times between landmarks in different time slots. A two-stage routing algorithm then computes a customized, practically fastest route for the user based on this graph and real-world trajectory data from over 33,000 taxis over three months. Evaluation found that 60-70% of routes suggested were faster than alternatives, with 20% sharing results, and on average routes
Cloudsim ranking on data manifold with sink points
This document provides an abstract for a paper on a novel ranking approach called Manifold Ranking with Sink Points (MRSP). MRSP addresses diversity, relevance, and importance in ranking by using manifold ranking over a data manifold to find relevant and important objects, while turning already ranked objects into "sink points" to prevent redundant objects from receiving a high rank. Experimental results on update summarization and query recommendation tasks showed MRSP performed better than existing ranking approaches by better addressing the importance of diversity in ranking.
Cloudsim quality-differentiated video multicast in multirate wireless networks
This document summarizes a research paper on providing differentiated quality video multicast in multirate wireless networks. It proposes a rate scheduling model that selects the optimal transmission bitrate for each video frame to maximize total visual quality while guaranteeing a minimum quality. It also presents a practical protocol called QDM that constructs cluster-based groups, adapts transmission rates based on quality perceived by cluster heads, and is suitable for real-time streaming. Simulation results show QDM can efficiently adapt to network dynamics and variable video bitrates, producing a 2-5 dB gain in average video quality over leader-based approaches.

The document proposes a power allocation scheme for statistical quality-of-service provisioning in multi-relay cognitive networks. The scheme first chooses between direct transmission or relay transmission based on channel state information. It then performs efficient power allocation according to the transmission mode and given constraints like quality-of-service requirements, average transmit power limits, and peak interference limits. Simulations show the proposed scheme outperforms max-min criterion and equal power allocation policies by achieving higher throughput while involving at most two relays for transmission.

Chopper based dc motor speed control
This document discusses using a chopper circuit to control the speed of a DC motor. A chopper circuit uses MOSFETs to vary the voltage applied to the motor, allowing for remote speed control. This method is more efficient and compact than previous variable resistor and transformer-based controls. Pressing buttons on the chopper circuit varies the MOSFET firing angle, decreasing motor speed as the firing angle increases. The chopper control reduces motor current, losses, temperature, noise, and increases motor lifetime compared to DC operation.

The document discusses channel allocation and routing in hybrid multichannel multiradio wireless mesh networks. It proposes an Adaptive Dynamic Channel Allocation (ADCA) protocol that considers both throughput and delay optimization in channel assignment.

Capacity of hybrid wireless mesh networks with random a ps
This paper proposes a hybrid wireless mesh network (WMN) architecture that allows the backbone to utilize random connections to access points (APs) in a wireless local area network (WLAN). Theoretical analysis shows that the capacity of a three-tier hybrid WMN is affected by the number of mesh router cells connected to APs, the ratio of access link bandwidth to backbone link bandwidth, and traffic balance among routers with AP access. Simulation results demonstrate that configuring APs and balancing traffic can significantly improve network capacity in the proposed hybrid architecture by taking advantage of wired connections through APs.

A single phase grid-connected fuel cell system based on a boost-inverter
- 1. A SINGLE-PHASE GRID-CONNECTED FUEL CELL SYSTEM BASED ON A BOOST-INVERTER ABSTRACT: In this paper, the boost-inverter topology is used as a building block for a single-phase gridconnected fuel cell (FC) system offering low cost and compactness. In addition, the proposed system incorporates battery-based energy storage and a dc-dc bidirectional converter to support the slow dynamics of the FC. The single-phase boost inverter is voltage-mode controlled and the dc-dc bidirectional converter is current-mode controlled. The low-frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the FC itself. Moreover, this system can operate either in a grid-connected or stand-alone mode. In the grid-connected mode, the boost inverter is able to control the active (P) and reactive (Q) powers using an algorithm based on a second-order generalized integrator which provides a fast signal conditioning for single-phase systems. Design guidelines, simulation, and experimental results taken from a laboratory prototype are presented to confirm the performance of the proposed system.
