摘要： The Photovoltaic (PV) system can supply electric energy to the load by direct conversion of solar energy through photovoltaic (PV) effect. The process in which solar energy is converted into electrical energy is known as photovoltaic effect. It is depend on the different circumstance by different equations of current and voltage based on mathematical modeling. It gives current and voltage of PV module by different no. of cells and variation in irradiation and temperature. The PV cell output voltage boosts-up by the boost converter and the AC grid by DC/AC converter (inverter) control the power. This module can be further connected to the utility grid connected system for commercial and industrial application. It is provides precise modeling of P-V characteristics of solar system.

[IEEE 2018 International Conference On Advances in Communication and Computing Technology (ICACCT) - Sangamner, India (2018.2.8-2018.2.9)] 2018 International Conference On Advances in Communication and Computing Technology (ICACCT) - Optimal Sizing of Battery-Ultracapacitor Hybrid Energy Storage Device in a Standalone Photovoltaic System
摘要： In standalone renewable energy systems, it is most essential to deploy energy storage devices to compensate for the intermittent and random output power generation. Since the last few years, hybrid energy storage devices (HESDs) composed of two or more energy storage technologies are being adopted in these power systems. In this paper, a standalone photovoltaic system with battery-ultracapacitor HESD has been considered for case study. A suitable problem formulation with the necessary objective function and constraints has been developed for the system. A variant of one of the popular meta-heuristic techniques, particle swarm optimization (PSO) has been used to address the optimization problem. The simulation results along with the convergence characteristics of the algorithm have been presented. It is observed that the proposed technique can produce comparable results.

Technoeconomic analysis of a grid-connected PV and battery energy storage system considering time of use pricing
摘要： This paper examines the technoeconomic optimization of the size of valve-regulated lead acid-type battery energy storage systems (BESSs) in order to minimize the total annual operating cost of a grid-connected photovoltaic BESS within the framework of system operational constraints, using the improved harmony search algorithm. The electricity cost is calculated using time of use pricing, where the price of energy varies according to the load demand. The concept of feed-in-tari? is discussed, where power can be bought from and sold back to the grid. A sensitivity analysis is performed for three cases: without storage, with storage and without peak load shaving, and with both storage and peak load shaving. The total annual operating cost of the system is calculated for all three cases and cost savings are compared. The simulations, performed with MATLAB, show a good optimization performance.

[IEEE 2018 7th International Conference on Renewable Energy Research and Applications (ICRERA) - Paris, France (2018.10.14-2018.10.17)] 2018 7th International Conference on Renewable Energy Research and Applications (ICRERA) - Improved Matlab Simulink Two-diode Model of PV Module and Method of Fast Large-Scale PV System Simulation
摘要： Nowadays, to response to the demand of a high rate renewable energy penetration in the electricity grids, the installation of many new large-scale photovoltaic systems up to more than 100 MW is unavoidable. However, in many countries, there is a serious lack of space for these large-scale projects. As the authorities wish to avoid taking away many farmlands for ground-mound photovoltaic systems, we must find acceptable ecological alternative solutions. One of the solution is the linear photovoltaic systems due to the availability and ready to use of the linear space: bike path, along the pavement of a road, along the edge of a highway… Another interesting method is the installation of floating PV power plants on inland water bodies. The possibilities and opportunities of these new kinds of large-scale PV plants are infinite. However, their installations meet a lot of challenges, such as the loss due to new structures and environments, the cost of equipment, the compatibility of the new PV plants with the initial function of the surface… To study these challenges, an effective simulation tool is essential. Considering the importance of the simulation tools, this paper proposes an improved PV system simulation model based on the two-diode model and a fast, comprehensive method to simulate the PV system in long term with a huge volume of the MATLAB/SIMULINK in environment.

摘要： In this work, a hybrid solar-battery feeding system is proposed to achieve a constant output power on a fixed-wing Unmanned Aerial Vehicle-UAV. Firstly, a single and hybrid power source configurations for long endurance UAV applications are exposed. Thus, a solar-battery based feeding system with a suitable energy management is proposed. Furthermore, a Maximum Power Point Tracking (MPPT) technique is selected to achieve the maximum efficiency of the solar photovoltaic (PV) array. Besides, Sliding-Mode Control (SMC) is implemented on a cascade control scheme in order to achieve a suitable energy conversion. Finally, the hybrid feeding system performance is analyzed for different solar radiation and load profiles remarking proper dynamic and steady-state responses.
