Presentation on shunt active filter
This paper proposes using a nonlinear autoregressive exogenous (NARX) feedback neural network for reference current generation in a 3-phase shunt active filter. The NARX network processes current quantities and a unit vector template to estimate the fundamental active component of the load current and the reference source currents. This allows determining the load current components for all three phases in a single step, without repeating calculations for each phase. Simulation results show the proposed method allows the shunt active filter to ensure sinusoidal and balanced supply currents at unity power factor under different load and supply conditions, with total harmonic distortion well within limits.
Cost of electricity generation
This document discusses economic dispatch in power systems. It begins by announcing homework and exam due dates. It then discusses how generation costs, including fuel and capital costs, contribute to retail electricity prices. Different generation technologies have varying costs. The document focuses on minimizing variable operating costs, primarily fuel costs, to meet demand by optimizing the generation dispatch. It provides details on modeling generation costs through input/output curves, fuel cost curves, heat rate curves and incremental cost curves. Examples are given to illustrate coal usage and incremental generation costs.

This document provides an abstract for a paper that proposes a new problem called Approximate Membership Localization (AML) for dictionary-based entity recognition. AML aims to locate non-overlapping substrings in a document that approximate true matches, without generating redundant overlapped substrings like Approximate Membership Extraction (AME) does.

Adaptive voltage control of the dcdc boost stage in pv converters with small ...
The document discusses an adaptive voltage control method for the DC/DC boost stage in photovoltaic converters that allows for a smaller input capacitor. Traditionally, PV systems use a large input capacitor for adequate voltage regulation to maximize power from the solar array. However, with a smaller capacitor the nonlinear characteristics of the PV array cause the voltage regulation performance to highly depend on the operating point. The paper analyzes these nonlinearities, proposes an adaptive control based on linearizing around the operating point, and validates the control through experiments on a commercial converter with a 40 μF capacitor connected to a 4 kW solar array.

This document analyzes distance-based location management schemes (DBLMS) in wireless communication networks. A Markov chain mobility model is developed to describe a mobile terminal's movement in a 2D cellular structure. Classical renewal theory is used to analyze the expected number of paging area boundary crossings and cost of the distance-based location update method for two different call handling models. The analysis makes it possible to find the optimal distance threshold that minimizes the total cost of location management in a DBLMS.

This document describes a method for detecting vehicles in dense urban areas using aerial images. The method uses Histogram of Oriented Gradients (HoG) features and disparity maps from at least two subsequent images along with exterior orientation data, a digital elevation model, and a road database. Road segments from the database are projected onto the images using height data. Disparity maps are used to exclude elevated objects like buildings and vegetation. Region growing excludes homogeneous areas, and remaining areas are classified using HoG features. The approach was tested on images of Munich, achieving up to 70% accuracy in vehicle detection.

This project illustrates the execution of a three stage delivery static compensator DSTATCOM by using a back propagation BP control algorithm for its capacities, such as load balancing and zero voltage management of reactive power compensation under non linear loads. We use BP based control algorithm to obtain the critical dynamic weight estimate here. And the BP based control algorithm is often used for estimating the receptive power portions of the load streams necessary for estimating the reference source streams. Regulation of power efficiency devices through neural networks is the new area of study in the field of power engineering. The extraction of the harmonic components defines the output of the balancing instruments. Here we use DSTATCOM and UPFC as balancing instruments. A DSTATCOM model is developed using a computerized signal processor and its implementation is focused on various working conditions. The execution of DSTATCOM is found to be suitable for various kinds of burdens with the proposed control algorithm. The BP based control algorithm is used to derive the fundamental weighted value of the active and reactive power components of the load present. Back propagation algorithm trained by the sample will detect the power quality signal issue in real time. Continuity, differentiability, non decreasing momotomy are the key features of this algorithm. The process of UPFC is close to that of DSTATCOM, although the only difference is that it does not have the device shut down in worse circumstances. The simulation model is developed with ANFIS and its output is studied under different operating conditions. The output of ANFIS is found to be satisfactory with the proposed control algorithm for different types of loads. The suggested method shall be checked by the results of MATLAB Simulink.

This document discusses the design of a STATCOM controller to regulate the voltage of an induction generator driven by a wind turbine. It proposes a mode decoupling STATCOM controller that uses eigenstructure assignment to decouple the active and reactive current control loops. Simulation results show the proposed controller more effectively regulates the generator terminal voltage during disturbances compared to controllers that do not use mode decoupling or neglect certain control gains. The controller is also experimentally validated on a laboratory setup consisting of an induction generator, STATCOM, and other system components.

This project shows how to use a back propagation BP control method to execute a three stage delivery static compensator DSTATCOM for its capabilities such as load balancing and zero voltage management of reactive power compensation under non linear loads. In this case, we utilize a BP based control method to determine the crucial dynamic weight. Furthermore, the BP based control method is often used to estimate the receptive power parts of the load streams required for estimating the reference source streams. The new topic of research in the field of power engineering is the regulation of power efficiency devices using neural networks. The output of the balancing instruments is defined by the extraction of the harmonic components. DSTATCOM and UPFC are used as balancing devices in this case. A DSTATCOM model is created with the help of a computerized signal processor, and its implementation is tailored to specific working circumstances. With the suggested control method, the execution of DSTATCOM is shown to be appropriate for a variety of workloads. The BP based control method is used to calculate the basic weighted value of the loads active and reactive power components. The sample trained back propagation method will identify the power quality signal problem in real time. This algorithms main characteristics include continuity, differentiability, and non decreasing momotomy. The UPFC procedure is similar to that of DSTATCOM, with the exception that the device is not turned off under adverse conditions. The simulation model is created using ANFIS, and its output is investigated under various operating circumstances. For various kinds of loads, the ANFIS output is determined to be acceptable using the suggested control method. The proposed technique must be validated using MATLAB Simulink findings.

Sensorless DTC of IPMSM for embedded systemsInternational Journal of Power Electronics and Drive Systems
This document summarizes a research paper on sensorless direct torque control of interior permanent magnet synchronous motors for embedded systems using an MRAS observer. It begins with an introduction to embedded systems and IPMSMs. It then provides the mathematical model of an IPMSM and describes the principles of direct torque control, including flux and torque hysteresis controllers and the inverter switching table. It presents an MRAS observer as a sensorless closed-loop algorithm for estimating rotor speed and position. In the simulation results, the proposed sensorless DTC control method using an MRAS observer is effective for embedded system applications.14. a variable speed, sensorless, induction motor drive
The document presents a new sensorless control strategy for a three-phase induction motor drive using only DC link current measurements. The strategy estimates motor speed and torque through signal reconstruction rather than direct sensor readings. It includes independent speed and torque control loops as well as current regulation. Simulation results on a 2.2 kW induction motor show fast dynamic response and good agreement between actual and estimated torque and speed values. The proposed drive requires only one current sensor in the DC link, making it suitable for low-cost sensorless motor applications.

Simulation and Design of SRF based Control Algorithm for Three Phase Shunt Ac...
Active power filters are effective in mitigating line
current harmonics and compensating for the reactive power
in the line. There are basically two types of Active Power
Filters (APFs): shunt type and series type. Shunt active power
filters (SAPFs) represent the most important and most widely
used filters in industrial purposes, this is due not only to the
fact that eliminate the harmonic current but also they are
suitable for a wide range of power ratings. In this paper,
Synchronous Reference Frame (SRF) theory is employed to
calculate compensating currents while the three phase source
is feeding a highly non-linear load. The main objective is to
study and investigate the performance of Shunt active power
filter using SRF theory. The algorithm is simulated under
M ATLAB

environment
using
Simulinkand
SimPowerSystems toolbox. The results shown are within the
IEEE Standard 512-1992.

- 1. ADAPTIVE THEORY-BASED IMPROVED LINEAR SINUSOIDAL TRACER CONTROL ALGORITHM FOR DSTATCOM ABSTRACT: This paper presents a hardware implementation of three-phase distribution static compensator (DSTATCOM) using an adaptive theory-based improved linear sinusoidal tracer (ILST) control algorithm for different functions of DSTATCOM such as reactive power compensation for power factor correction, harmonics elimination, load balancing, and zero-voltage regulation under linear/nonlinear loads. An ILSTbased control algorithm is used for the extraction of fundamental load currents and their active and reactive power components. These components are used for the estimation of reference source currents. A prototype of DSTATCOM is developed and its real-time performance is studied using a digital signal processor. The performance of DSTATCOM is found satisfactory with the proposed control algorithm under various types of loads.
