Smart Home Power Management System using Wireles

Smart Home Power Management System using Wireles

The purpose of the Smart Power Management System(SPMS) is everything necessary to maintain complete comfort in a residential environment, energy and economic costs saving through efficient power measurement and distribution.
Existing Korea energy policies have focused stable and economic power supply. Therefore industry comes up with a social develop through power infra. However it caused the indiscriminate power use. The saving of energy is all-important to our country, which lacks petroleum resources. Also complex and population growth have required the more energy demand because of industrial developments. Our domestic marketing is yet to apply the passive system, self-produced distribution of energy is maintaining ineffectually. In other words, recently to reduce the energy consumption it depends on the self-devices performance and keeps the passive energy management(insulation use etc). In overseas market is developing the active system. In order to apply the active system that needs the intelligent electronics control, smart context-aware monitoring, renewable energy technology of smart grid connection, cloud engine technology based on home network, air conditioning and heating control via environment integration management, remote control technology. To achieve the effective home power management system that requires a lot of tech. The power management system based on home network can contribute the energy life time via efficient energy distribution such as intelligent home management. Through the application of study that prospect the CO2 and energy cost reduction and make comfort residential environment.

Recently,integrating are new able energy source,such as solar energy or
wind power, to distributed generation microgrid is widely developed
nowadays.The cost and efficiency of the system may be taking into
accountas an important consideration.A large powersystem consists of
several parallel inverters which work redundantly,in order to keep the
reliability of the system. In addition, several same capacity parallel
inverters may be operated as modular inverters,that may have lower
operation cost.In modular inverter operation,the load sharing between
inverters must be considered. Furthermore, the transition between
grid-connected and stand-alone mode may causing bad influence to the
critical load.
In this paper,a master-slave control algorithm with seamless transfer
during mode transition of modular parallel inverter as PCS for ESS is
proposed.

Sistema de geração distribuida fontes CA e CC conectado a rede monofasica e controle eletronico da qualidade da energia eletrica Ricardo Quadros Machado : Faculdade de Engenharia Elétrica e de Computação - FEEC-UNICAMP-BRASIL

Título [Principal]: Sistema de geração distribuida fontes CA e CC conectado a rede monofasica e controle eletronico da qualidade da energia eletrica
Título [Outro Idioma]: Distribution generator systems with AC and DC sources connected to a single-hase feeder and electronic control of the power quality
 Autor(es): Ricardo Quadros Machado

Resumo: Resumo: Esta tese apresenta uma nova forma de conexão direta entre um gerador de indução trifásico e uma rede monofásica, situação típica de ambientes rurais, com possibilidade de geração local de energia. O funcionamento do sistema prevê que seja garantida ao usuário local energia elétrica de boa qualidade. Por energia de boa qualidade entende-se: tensões senoidais e equilibradas, freqüência fixa e boa regulação de tensão. Para a rede monofásica, controla-se o fluxo de potência de modo que o fator de potência resultante seja unitário. A obtenção destes comportamentos se dá com o uso de um conversor CC-CA PWM trifásico, conectado em derivação no ponto de acoplamento das cargas locais. Por este conversor flui uma parcela da potência da carga relacionada com desequilíbrios e distorções. A maior parte da potência ativa não precisa ser processada pelo conversor, o que dá a esta solução um rendimento maior do que se obtém com as alternativas de dupla conversão. O sistema completo de geração distribuída pode receber energia, da geração CA (gerador de indução), de uma fonte CC (células a combustível, painéis fotovoltáicos ou bancos de baterias) conectada ao barramento CC do conversor PWM ou da rede monofásica. No caso de alimentação apenas pela rede, tem-se uma estrutura de conversão mono-trifásica interativa com a linha.

ABSTRACT
In order to develop precise solar cell simulators or design a high
performance photovoltaic generation system, it is important to
accurately understand physical properties of solar cells. But the
steady state model of the solar cell have a non-linear form with
many parameters entangled and conventional methods suggested to
extract the parameters of the solar cell model require some kind of
assumptions, which accompanies the calculation errors, thereby
lowering the accuracy of the model.In the first half of the paper,a
novel method of extracting values of parameters is proposed.The
proposed method deduces characteristic curve of an ideal solar cell
using solar cell equation,and extracting the parameters from the
difference between the ideal and measured I-V curve.

A Single-Phase Current Source Solar Inverter with Constant Instantaneous Power, Improved Reliability, and Reduced-Size DC-Link Filter Bush, Craig R. (Author) ARIZONA STATE UNIVERSITY December 2013

A Single-Phase Current Source Solar Inverter with Constant Instantaneous Power, Improved Reliability, and Reduced-Size DC-Link Filter
by Craig R. Bush
A Dissertation Presented in Partial Fulfillment
of the Requirements for the Degree Doctor of Philosophy

Abstract
 This dissertation presents a novel current source converter topology that is primarily intended for single-phase photovoltaic (PV) applications. In comparison with the existing PV inverter technology, the salient features of the proposed topology are: a) the low frequency (double of line frequency) ripple that is common to single-phase inverters is greatly reduced; b) the absence of low frequency ripple enables significantly reduced size pass components to achieve necessary DC-link stiffness and c) improved maximum power point tracking (MPPT) performance is readily achieved due to the tightened current ripple even with reduced-size passive components. The proposed topology does not utilize any electrolytic capacitors. Instead an inductor is used as the DC-link filter and reliable AC film capacitors are utilized for the filter and auxiliary capacitor. The proposed topology has a life expectancy on par with PV panels. The proposed modulation technique can be used for any current source inverter where an unbalanced three-phase operation is desires such as active filters and power controllers. The proposed topology is ready for the next phase of microgrid and power system controllers in that it accepts reactive power commands. This work presents the proposed topology and its working principle supported by with numerical verifications and hardware results. Conclusions and future work are also presented.

Design of Inverter for LCD TV Backlight
with Flat Fluorescent Lamp

The liquid crystal display(LCD) TV market has been growing continuously and cost reduction is one of the biggest issues to increase its market share. The LCD needs backlight because it belongs to non emissive displays. The cold cathode fluorescent lamp (CCFL) and external electrode fluorescent lamp (EEFL) are widely used in backlight system for LCDs. But assembly of CCFL and EEFL backlight system is very complex. The flat fluorescent lamp (FFL) is a newly developed light source and it has a very simple structure. The LCD backlight can have a simple structure if the newly delvelop FFL is used as a light source. The backlight with FFL can be more cost effective than that of the backlights with CCFL or EEFL light sources. But the temperature behaviour of FFL backlights are different from the backlight with CCFL or EEFL light sources, which prohibits FFL backlight from being accepted as the backlight for commercial application.
