“…Assim, para a potência nominal de 1 kW serão necessários tipicamente 5 módulos em série. Idealmente, quanto menor o número em associação melhor a eficiência do algoritmo de MPPT [3]- [7]. Para prover a potência necessária, adotou-se um arranjo de 5 módulos em série, com tensão equivalente de 135 V e corrente de 7,7 A, resultando em 1040 W de potência ativa no MPP.…”

“…Quando se considera a microgeração distribuída, a fonte fotovoltaica provê baixa tensão CC (contínua) que demandará um conversor elevador provido de um algoritmo de MPPT (maximum power point tracking) com elevado fator de rastreamento [3]- [7], vida útil compatível com os arranjos fotovoltaicos, além de baixo conteúdo harmônico para as correntes injetadas na rede em CA (corrente alternada). Estes critérios podem ser determinantes para o uso atual e futuro destas fontes alternativas e renováveis de energia tais como a solar e eólica uma vez que as aplicações mais desejadas são aquelas conectadas à rede de distribuição, sem armazenamento de energia, onde todos os benefícios da geração distribuída podem ser alcançados [1]- [4].…”

Resumo -Este artigo apresenta comparações entre estruturas monofásicas a duplo estágio não isoladas, para aplicações em geração distribuída fotovoltaica (GD-FV), em conexão à rede de distribuição em baixa tensão. Considerando aplicação para GD-FV observou-se vantagens significativas para conversores com características naturais de fonte de corrente para a entrada, fato que reduz a capacitância de desacoplamento do sistema FV. ANALYSIS OF SINGLE-PHASE NON-ISOLATED INVERTER STRUCTURES APPLIED TO PHOTOVOLTAIC DISTRIBUTED GENERATIONAbstract -This paper presents comparisons among non-isolated DC to AC double-stage single-phase structures, applied to photovoltaic distributed generation (PV-DG), suitable to operate connected to the AC electric power network. Considering the PV-DG application, this paper has focused on converters with natural current source input characteristic which allows low capacitance value required for PV power decoupling. Simulation results and qualitative analysis are presented and experimental results from an application are discussed in order to confirm the feasibility of the proposal. The developed prototype is digitally controlled by a DSC, considering the designed firmware for MPPT, and in agreement with NBR-IEC 62116:2012 standard, including islanding and electrical protections.

“…The overall efficiency of photovoltaic systems dramatically decreases due to panel mismatching [16,17], switching losses in the PV inverter [18,19], maximum power extraction losses [20], and cable conduction losses [21,22]. The power losses become important in complex photovoltaic configurations, like those integrated in roofs and facades, or in large PV systems.…”

Abstract:The increasing penetration of renewable sources with power-electronic interfaces in power systems is raising technical problems and the overall efficiency of photovoltaic systems can decrease dramatically. In this context, the optimal layout for the photovoltaic system is required. The most adequate strategy to connect the renewable system to the electrical power grid or to supply the end users must be adopted. The present paper proposes a design layout of a PV plant using a DC bus system to improve the overall energy conversion efficiency. An analysis of steady-state system stability, voltage drop and DC cable conduction losses is conducted. The leakage currents to the ground are investigated through simulations. Experimental results are shown focused on the analysis of optimal layout of photovoltaic systems under particular operating conditions.

-Maximum Power Point Tracking (MPPPT) techniques are employed in PV systems to make full utilization of PV array output power which depends on solar irradiation and temperature. Recently, many MPPT algorithms and control schemes of PV system have been proposed, but different control methods and different PID controller parameters lead to different output efficiency and dynamic response. Therefore, in this paper, a PSCAD/EMTDC user defined module of the solar array is established to easily simulate its inherent characteristics with the basic specification data. Moreover, we also compare the advantages and weakness of the existing MPPT control methods by simulations to give a reference to the Grid-Connected Photovoltaic System (GCPS) designers.
