a comprehensive study on different types of faults and detection techniques for Solar Photovoltaic System
Solar Energy, 2017Co-Authors: Siva Ramakrishna Madeti, S N SinghAbstract:Abstract Monitoring Systems are essential to maintain optimal performance of Photovoltaic (PV) Systems. A critical aspect in such monitoring Systems is the fault diagnosis technique being used. The role of a fault detection and diagnosis technique is to identify the causes affecting the real-time energy production and/or smooth functioning of PV Systems. Over the past decade, various fault detection methods were reported in literature. Among all the fault detection techniques reported, some paid significant attention only on faults that occur in the PV System, some on faults on DC side of the PV System while the rest focused on AC side faults. For the first time, this paper provides a comprehensive review of popular fault detection techniques, addressing all major types of faults in PV Systems. Detailed insights of PV fault detection techniques along with their relative performances are covered. A new fault detection technique is also proposed to identify the type and location (module level) of a fault. This review enables the reader to get acquaintance with major aspects/considerations in developing/choosing an effective yet viable fault detection technique for small and medium scale PV Systems.

selection of non isolated dc dc converters for Solar Photovoltaic System
Renewable & Sustainable Energy Reviews, 2017Co-Authors: G Dileep, S N SinghAbstract:Abstract Concerns over environment and increased demand of energy have led the world to think about alternate energy sources such as wind, hydro, Solar and fuel cells. Out of these, Photovoltaic (PV) power generation Systems have become increasingly important all over the world due its availability, cleanness, low maintenance cost and inexhaustible nature. But power produced by the Photovoltaic System is stochastic in nature due to the variation of Solar irradiation and cell temperature throughout the day. In order to track the varying power, a DC-DC converter with maximum power point tracker (MPPT) is used. Different MPPT algorithms have been proposed for tracking peak power from the PV panel. Selection of adequate DC-DC converter is also an important factor since it has an influence on overall performance of the PV System. This paper presents a comparative study on the characteristics of different non-isolated DC-DC converters and highlights the various research works that has been done on DC-DC converters based MPPT PV System. Study shows that selection of converter also has an impact on the overall performance of the PV System. Based on the survey and comparative study, selection criteria to choose DC-DC converter for PV System is described in this paper.

Renewable & Sustainable Energy Reviews, 2015Co-Authors: G Dileep, S N SinghAbstract:Solar energy is one of the important renewable energy resources as it is pollution free, clean, never-ending and abundant. Solar Photovoltaic technologies are mounting vigor attention in the modern electrical power applications due to fast growth in the relative sectors of semiconductor and power electronics. It is significant to operate Solar Photovoltaic energy conversion Systems to its maximum power output to raise the efficiency. Maximum power point tracking plays a very important role for extracting maximum power from the Solar Photovoltaic module and transferring that power to the load. The present work highlights a survey on perturb and observe method maximum power point tracking technique for Solar Photovoltaic System undertaken by considering the various works already listed relative study has been carried out, which includes different perturb and observe method on maximum power point tracking techniques and draw their advantages and drawbacks. These techniques vary in many aspects, which can be broadly categorized on the basis of simplicity, way of implementing, type of sensors, total cost of the System, range of effectiveness, hardware requirement and speed of convergence. It is expected that this review work will provide precious information for Solar Photovoltaic professionals to keep alongside with the latest progress in this area, as well as for new researchers to get started on maximum power point tracking.

review article a review of particle swarm optimization and its applications in Solar Photovoltaic System
Applied Soft Computing, 2013Co-Authors: Anula Khare, Saroj RangnekarAbstract:Particle swarm optimization is a stochastic optimization, evolutionary and simulating algorithm derived from human behaviour and animal behaviour as well. Special property of particle swarm optimization is that it can be operated in continuous real number space directly, does not use gradient of an objective function similar to other algorithms. Particle swarm optimization has few parameters to adjust, is easy to implement and has special characteristic of memory. Paper presents extensive review of literature available on concept, development and modification of Particle swarm optimization. This paper is structured as first concept and development of PSO is discussed then modification with inertia weight and constriction factor is discussed. Issues related to parameter tuning, dynamic environments, stagnation, and hybridization are also discussed, including a brief review of selected works on particle swarm optimization, followed by application of PSO in Solar Photovoltaics.

a bottom up approach for estimating the economic potential of the rooftop Solar Photovoltaic System considering the spatial and temporal diversity
Applied Energy, 2018Co-Authors: Minhyun Lee, Taehoon Hong, Kwangbok Jeong, Jimin KimAbstract:Abstract To successfully deploy distributed Solar generation in urban environments, it is essential to investigate the potential to generate electricity from the rooftop Solar Photovoltaic (PV) System within a region. While various interpretations are possible for the rooftop Solar PV potential, most of the previous studies focused on estimating the technical potential, not considering the economic viability and market dynamics. Therefore, it is necessary to estimate the economic potential of the rooftop Solar PV System to quantify the amount of economically viable Solar PV energy within a region and to evaluate the impact of the various factors affecting market access. Towards this end, this study proposed a bottom-up approach for estimating the economic potential of the rooftop Solar PV System considering the market dynamics by adoption year. Accordingly, the economic potential of the rooftop Solar PV System was estimated for the Gangnam district in Seoul, South Korea from 2008 to 2016. In terms of power capacity, it was analyzed that as of 2016, the actual installed capacity of the Solar PV System in the Gangnam district was only 3% of the maximum economic potential of the rooftop Solar PV System (i.e., economic potential for electricity business purposes), showing a high potential for additional rooftop Solar PV adoption. In terms of electricity generation, it was shown that as of 2016, the annual economic potential of the rooftop Solar PV System could supply up to 4.48% of the annual electricity consumption in the Gangnam district, while only 0.12% could be supplied from the annual electricity generation of the actual installed Solar PV System. This study has significant contributions in that it took one step farther towards the rooftop Solar PV potential estimation process, from the technical potential to the economic potential, considering the spatial and temporal diversity of the Solar PV technology.
