Analysis of power efficient compressor with fuzzy logic MPPT-based PV/FC system
摘要： In this paper, a hybrid photovoltaic (PV)/fuel cell (FC) power generation system is considered, where the hydrogen generated by the electrolysis process is used for subsequent FC operation. A novel induction motor-based compressor is proposed to boost up the pressure of hydrogen, and hence to improve the performance of the FC system. A fuzzy logic-based maximum power point tracking (MPPT) system is designed for the considered PV system. Finally, a coordinated control scheme is applied for controlling the power supplied to the load by integrating both the sources. The complete model is realised in the MATLAB/Simulink environment. Extensive simulation studies are conducted to verify the developed model. The performance of the complete system is found satisfactory under different conditions.

Design and development of distributed solar PV systems: Do the current tools work?
摘要： Distributed solar PV design and management in buildings is a complex process which involves multidisciplinary stakeholders with different aims and objectives, ranging from acquiring architectural visual effects to higher solar insolation in given location, efficient energy generation and economic operation and maintenance of the PV system. Therefore, proper PV design tools are necessary for achieving unique aims, objectives and performance goals of a PV project. This paper presents 23 solar PV design and management software and 4 smart phone/tablet applications, analyzing their features against 15 key aspects of solar PV design and management. The results show that the selected PV design and management tools cannot satisfy all aspects of PV design and management. 14 solar PV design and management application problems were identified. An integrated platform which will provide cost-effective solutions for PV project development is proposed at the end of the paper. The proposed platform should open a new outlook on potentially wider multidisciplinary usage of solar PV design and management tools world wide.

LCO-FLL control for single-phase utility integrated single-stage solar PV system
摘要： This study presents a limit cycle oscillator-frequency locked loop (LCO-FLL) control for single-phase utility integrated single-stage photovoltaic (PV) system. The proposed topology increases the utility of the voltage-source converter (VSC), particularly in the absence of PV generation. It has the potential to load harmonics current mitigation. It estimates harmonic free load current accurately with low computational requirement due to the absence of cumbersome mathematical algorithm and transformation techniques. It provides reactive power compensation, both in the absence and the presence of PV generation, improves transient response during dynamics in load and varying irradiance conditions. The total harmonic distortions of utility current and utility voltage, compliance the limit of the IEEE-519 standard. The proportional–integral (PI) regulator regulates the DC-link voltage of VSC input to the reference DC-link voltage. The incremental conductance-based technique derives the reference DC-link voltage. The dynamic behaviour of the LCO-FLL-based control is improved using a feed-forward loop for the PV power sharing. It also reduces loading on the PI controller. Test results demonstrate satisfactory performance of LCO-FLL-based control.

摘要： Use of solar PV cells to harness electricity has been more developed in recent years. Researchers are more focusing on to extract more power from available area. But more consideration should be given to the energy loss during power extraction. Because the energy loss means the wastage of available power .The one of the solutions to save energy loss is the power plant monitoring. This paper describes the design of remote data acquisition system for solar plant using internet of things. The solar power plant monitoring will provide the real time data for net power, net/total energy and irradiance. This data will be helpful to take decision to schedule operation & maintenance activities & preventive maintenance.

A multi verse optimization based MPPT controller for drift avoidance in solar system
摘要： This paper proposes Multi verse optimization (MVO) based MPPT controller to mitigate the possibility of losing tracking direction in solar photovoltaic system under variable irradiance. Generally conventional Perturb & Observe and hill climbing MPPT techniques are used due to effortless implementation. However, these techniques are not capable of handling oscillations in power at MPP and exhibit drift under variable irradiance conditions which leads to power loss. Therefore a hybrid of standard MVO and direct duty cycle control is proposed to minimize the inadequacies occurring in conventional controllers. Three cases i.e. constant irradiance, rapid and step changes in irradiance are considered for the analysis. The supremacy of proposed method is justified by comparing it with traditional P&O, Particle swarm optimization (PSO) based MPPT and Grey wolf optimization (GWO) based MPPT techniques. It is observed from the results that MVO based MPPT controller is capable of avoiding drift and offers fast convergence. Therefore proposed controller outperforms in terms of tracking efficiency, settling time, peak overshoot, and integral absolute error.

摘要： In this paper a comparative analysis between Distributed Power Flow Controller (DPFC) and Unified Power Flow Controller (UPFC) integrated photovoltaic system is performed. A grid connected solar generation system with boost converter and voltage source inverter (VSI) is taken as the main model. Due to power quality issues like power oscillations, harmonic distortions, voltage sags and swells, the grid side system has to be perfectly monitored and controlled. One way to mitigate these power quality problems is by using reactive elements like shunt/series reactor and shunt/series capacitor. The disadvantage is sub synchronous resonance phenomenon. Thanks to FACTS technology, which emerged out as power conditioning units and helps to feed power with required standards and free from power quality issues. Among them, the contemporary FACTS devices are Controller (DPFC) and Unified Power Flow Controller (UPFC) .Though the aims of both the devices are same but their working principles are different. In this paper the effect of adding a DPFC and UPFC to a solar PV generation system is analyzed. A detailed working principle and operation of both the devices were presented. At last, MATLAB/SIMULINK environment is used to compare the performances of above mentioned devices.

The system makes use of a single phase power converter connected to the grid through an LCL filter. A robust LQRI controller is designed to incorporate added functions such as power line conditioner, active power regulator, and voltage stabilizer. The perturb and observe (P&O) algorithm is used to generate the reference signal for the fluctuating DC bus voltage as well as to extract the maximum power from the solar panels. Full modeling of the converter in the D-Q reference frame is presented. A Linear Quadratic Regulator with added Integral action (LQRI) is designed to achieve optimal multi-functionality operation of the residential power supply.
