[IEEE 2018 IEEE International Students' Conference on Electrical, Electronics and Computer Science (SCEECS) - Bhopal, India (2018.2.24-2018.2.25)] 2018 IEEE International Students' Conference on Electrical, Electronics and Computer Science (SCEECS) - A Five –level PWM Inverter for Hybrid PV/Fuel Cell/Battery Standalone power System
摘要： Renewable energy sources (RES) based generation has emerged as one of the best option due to global environmental concerns, especially for off-grid load locations like islands, mountains, etc., where diesel generators are main source of power generation. This paper presents a case study of an efficient photovoltaic (PV) generation integrated with multilevel inverter to ensure regulated power at user end. Perturb and observe (PO) algorithm based maximum power point tracking (MPPT) has been used to track maximum power for PV applications. However in PV based power generation, control problem arises due to large variation of irradiance round the clock. This problem can be overcome by hybrid PV generation system, i.e., application of secondary power source as battery and fuel cell integrated with PV generation unit. The DC output of standalone hybrid PV-SOFC-Battery generation system is inverted by a single-phase multilevel converter. This output of developed standalone hybrid PV-SOFC-Battery generation system is used to supply the single-phase load. This inverter offers less THD which is compared with three level inverter.

[IEEE 2018 International Conference on Power, Energy, Control and Transmission Systems (ICPECTS) - Chennai (2018.2.22-2018.2.23)] 2018 International Conference on Power, Energy, Control and Transmission Systems (ICPECTS) - Design and Hardware Implementation of Self Lift Negative Output Luo Converter Using MPPT for PV Applications
摘要： The design and analysis of self lift N/O luo converter is discussed in this paper. The incremental conductance mppt extracts the maximum power from PV panel and transfers to the load. The PV panel is designed by using equivalent circuit of PV cell. The output obtained from the solar panel contains more ripples. The ripples will produce more fluctuations. By using self lift negative output luo converter the unregulated output will be conveted into regulated voltage and stepped up to the higher voltage. For obtaining simulation results Matlab software is used.

Performance Analysis of Maximum Power Point Tracking Algorithms Under Varying Irradiation
摘要： Photovoltaic (PV) system is one of the reliable alternative sources of energy and its contribution in energy sector is growing rapidly. The performance of PV system depends upon the solar insolation, which will be varying throughout the day, season and year. The biggest challenge is to obtain the maximum power from PV array at varying insolation levels. The maximum power point tracking (MPPT) controller, in association with tracking algorithm will act as a principal element in driving the PV system at maximum power point (MPP). In this paper, the simulation model has been developed and the results were compared for perturb and observe, incremental conductance, extremum seeking control and fuzzy logic controller based MPPT algorithms at different irradiation levels on a 10.2 kW PV array. The results obtained were analysed in terms of convergence rate and their efficiency to track the MPP.

An Efficient Technique using Modified p-q Theory for Controlling Power Flow in a Single-Stage Single-Phase Grid-Connected PV System
摘要： In this paper, an efficient power conditioning unit (PCU) is presented for a single-phase grid-connected photovoltaic system (GCPVS) incorporating both maximum power-point tracking (MPPT) and current control algorithms in a single-stage. Modified p-q theory is applied to derive the reference signal for a hysteresis band current (HBC) controller so that independently the active and reactive power sharing between the photovoltaic (PV) system and the grid can be controlled. Enhanced stability during the internal dynamics, caused by the variations in PV generation and load conditions, is the prime aspect of the controller. The performance of the proposed p-q theory correlated HBC controller is evaluated against tracking of maximum PV power and compensation of load reactive power under the changeable atmospheric and load conditions, and also compared with the widely used conventional proportional resonant (PR) controller to justify superiority. Simulation and experiment are carried-out under variable weather and different load conditions to validate acceptability of the proposed control scheme.

[IEEE 2018 4th International Conference on Renewable Energies for Developing Countries (REDEC) - Beirut, Lebanon (2018.11.1-2018.11.2)] 2018 4th International Conference on Renewable Energies for Developing Countries (REDEC) - The first BIPV plant in Lebanon: performance analysis of hybrid configuration with diesel generator
摘要： Building integrated photovoltaic (BIPV) system is a technology where radiant energy and heat are treated. This system helps in developing the building to become energy producer instead of energy consumer. It can function as buildings envelop and supply electric power for buildings. In this paper, a pilot BIPV system is studied with respect to aesthetical and technical requirements, and installed on the fa?ade of an office building in Beirut. The aim of the research is to test the energy performance of the BIPV system through modelling and experimental investigation in hybrid configuration with building back-up diesel generators – a Lebanese particularity due to utility shortage in power supply. This first BIPV project in Lebanon has a capacity of 30 kWp. It has a special architectural integration benefiting from available solar energy estimated to be around 2000 kWh/m2/ year to produce electric power, and reduces the consumption of diesel generators that runs the building during working hours.

[Energy, Environment, and Sustainability] Advances in Solar Energy Research || Techno-Economic Potential of Large-Scale Solar Deployment in the US
摘要： PV system generates electricity with minimum environmental impact reduces than conventional greenhouse gas emission and consequently reduces the effects of global warming. In late of 2014, the Indian government announced an ambitious target of 100 GW installation capacity of solar PV systems by 2022. Since then, India has achieved notable progress towards this goal and has installed 20 GW cumulative solar capacity with 9.6 GW in 2017 alone. Based on the 2015 MIT Energy Initiative, by 2050, a major fraction of the world’s electric power will come from solar sources. However, this poses many technical and economic challenges on the electrical infrastructure. In this chapter, we focus on the US case, by studying the technical and economic potentials of large-scale deployment of the most commonly recognized types of solar; photovoltiac (PV) and concentrated solar power (CSP) at different locations in the US. The technical potential is assessed based on grid interconnection topologies, and solar system performance. The economic potential is evaluated based on several metrics such as the levelized avoided cost of energy (LACE) and levelized cost of electricity (LCOE), and the possibility of integration into the electricity markets. The economic potential also covers the subsidies, taxes, policies, and incentives for large-scale solar deployment. Two simulation case studies are implemented on two large-scale solar PV and CSP projects at different locations in the US to evaluate their techno-economic potentials.

摘要： This paper presents an intelligent method to extract the maximum power from the photovoltaic panel using artificial neural network (ANN). The inputs data required for training the ANN controller are obtained from real weather conditions and the desired output is obtained from perturb and observe (P&O) method. The proposed model is capable to improve the dynamic response and steady-state performance of the system, provides an accurate identification of the optimal operating point and an accurate estimation of the maximum power from the photovoltaic panels. The proposed ANN model is compared with conventional P&O model and shown that ANN controller could increase the power output by approximately 20%.

Improved cooperative artificial neural network <scp>a??</scp> particle swarm optimization approach for solar photovoltaic systems using maximum power point tracking
摘要： Photovoltaic (PV) energy represents one of the most important renewable energies, but its disadvantage resides in its maximum power point, which varies according to meteorological changes that make the efficiency low. Intelligent techniques, using the maximum power point tracking (MPPT) method, can achieve an efficient real-time tracking of this point in order to ensure optimal functioning of the system. The output power of the PV system is removed from solar irradiation and cell temperature of the PV panel type SOLON 55W. Therefore, it is essential to harvest the generated power of the PV system and optimally exploit the collected solar energy. For this objective, this work treats on a new artificial neural network-particle swarm optimization approach (ANN-PSO). The ANN is used to predict the solar irradiation level and cell temperature followed by PSO to optimize the power generation and optimally track the solar power of the PV panel type SOLON 55W based on various operation conditions under changes in environmental conditions. The simulation results of the proposed approach give a minimum error with a relevant efficiency, that is, the power provided by ANN-PSO approach is optimal and closer to the PV power. Consequently, this novel approach ANN-PSO shows its major capability to extract the optimal power with excellent efficiency up of 97%. For this objective, this work treats a new hybrid ANN-PSO approach.

Voltage Quality Improvement Using Solar Photovoltaic System
摘要： Solar power and wind are the most promising distributed energy sources. The photovoltaic system has attracted significant attention in recent years. Although their benefits are numerous, they are known to create power quality issues, because of the power electronic converters they use. This paper investigates if there is a possibility to improve power quality only by connecting a solar photovoltaic system to the grid, and then gives results of on-site power quality measurements in the grid before and after the connection of the solar photovoltaic system.

Global MPPT of photovoltaic system based on scanning method under partial shading condition
摘要： The partial shading (PS) of the photovoltaic (PV) array is a major problem for the PV systems. Therefore, it is necessary to extract the global maximum power point (GMPP) under partial shading. In this paper, we propose a simple method to find the GMPP. This method scans the P–V curve and memorizes all the peaks in order to get the global peak. Next, we control a boost DC–DC converter to extract the GMPP from the PV system. In addition, this Method allows following the dynamic GP under variant SPs with less oscillations around the stable state compared to the existing works.
