  • Review on Phase Change Material Storage in Solar Energy Application
    Applied Mechanics and Materials, 2014
    Co-Authors: Ye Zhang, C. Chen, D.-w. Qi
    Abstract:

    Use Solar Energy as a complement of building heating Energy, not only the building consumption will be reduced but also the air pollution problem during winter can be improved. However, the sparseness, discontinuity and instability of the Solar Energy are bottleneck of Solar Energy utilization technology. Thus the thermal storage technology becomes the most important part in Solar Energy system. Phase change thermal storage technology is more efficient then water, and it can charge the surplus Solar Energy for cloudy days to improve the utilization rate of Solar Energy. The performance of Solar system can be improved by using phase change material storage technology. This review summarizes the previous study on phase change materials storage in Solar Energy Application; the content of this paper can provide a reference for relative studies.

Introduction The rapid growth of Energy consumption brought the environmental impacts issues such as greenhouse gas emissions, air pollution and globe warming. Building is the largest sector of Energy consumption and CO 2 emission, it represent 32% of total final Energy consumption. In terms of primary Energy consumption, buildings represent around 40% in most countries[1]. Furthermore heat (space heating plus domestic hot water) is about 75% of the Energy consumed in buildings [2]. In this case, green Energy such as geothermic, ground heat and Solar Energy is adopted as heating Energy. According to[2]the earth receives from the sun each hour as much Energy as mankind consumes in a year, thus the Solar Energy is the primary green Energy source for building heating. But the Solar Energy is intermittent and unequally distributed, only available during daytime, and more important when heating demand is greater in winter, the Solar Energy is weaker. Therefore thermal Energy storage is one of the most efficient ways to reduce the mismatch between Solar Energy supply and heating Energy demand. Sensible heat storage and latent heat storage are two common ways in thermal Energy storage. Water and phase change material (paraffin) thermal storage is respectively represent sensible and latent heat storage. And compare the volume requirements for the thermal Energy storage between water and phase change material (paraffin or hydrated salts), it is apparently that the water heat storage requires almost 4-5 times amount of space. For most building Solar heating requirement, there are not enough space for such amount water, using phase change materials for thermal storage can provides a high heat storage density during the phase change process and reduce the installation space saving initial cost. Use phase change material heat storage technology in Solar heating system can meet the demand for indoor heat requirement and has attracted growing attention due to this in achieving Energy conservation in buildings.This review summarizes the previous study on Solar heating system with phase change materials thermal storage technology; the content of this paper can provide a reference for relative studies.

  • a novel framework for the potential assessment of utility scale photovoltaic Solar Energy Application to eastern iran
    Energy Conversion and Management, 2017
    Co-Authors: Hamed Hafeznia, Hossein Yousefi, Fatemeh Razi Astaraei
    Abstract:

    Abstract This paper presents a framework to assess the potential of photovoltaic Solar Energy for utility-scale installations. In order to achieve this purpose, the framework incorporates spatial planning and performance simulation of photovoltaic power systems into the potential assessment process. Birjand County where is a suitable region for the deployment of photovoltaic technologies because of its climatic conditions was selected as a case study. The installation of Solar power plants as a subset of infrastructure facilities should have the conformity to the standards of land-use planning. At the first step, the set of factors (27 criteria) influencing on the site selection of photovoltaic power plants was defined. After the detection of unsuitable areas, they were excluded from the county map by Boolean logic. Remaining areas were rated based on the technical, socio-economic, environmental criteria by using different fuzzy membership functions. Then, these rated areas were mapped. To determine the optimal sites for the grid-connected installations of photovoltaic, the fuzzified maps were overlaid by fuzzy gamma operator. Then, the pixels of final map were classified into five groups regarding to their fuzzy value. The results show that optimal places for the installation of photovoltaic power plants account for 0.5 percent (2005 hectares) of Birjand’s territory. The results of geo-spatial modeling of this thesis were verified by using satellite images. To estimate the capacity of electricity production from photovoltaic power plants, a 46.2 kW- photovoltaic installation was designed and its performance and Energy output was simulated under climatic and geographical conditions of Birjand. The estimated Energy output of photovoltaic power plants in optimal sites of Birjand County (1781.6 GW h/year) not only can supply the electrical demand of Southern Khorasan Province but also, the excess generated electricity can export to other provinces and neighboring countries such as Pakistan and Afghanistan.

  • a review on favourable maximum power point tracking systems in Solar Energy Application
    TELKOMNIKA Telecommunication Computing Electronics and Control, 2014
    Co-Authors: Awang Jusoh, Tole Sutikno, Tan Kar Guan, Saad Mekhilef
    Abstract:

    This paper reviews different types of maximum power point tracking (MPPT) techniques for Solar photovoltaic (PV) Application. Since the PV output power is known affected by sun radiation and temperature, it is necessary to search for an effective method for extracting maximum amount of power from PV cell/modules. In this study, a total of seven control algorithms were selected, comprising the most popular methods among the established techniques. A comparison in terms of convergence speed, complexity, as well as the basic concept of each method had been carried out for future reference. Based on the accessible simulation results, modified Perturb and Observe (P&O) method had shown its effectiveness for obtaining actual maximum power point while solving major drawbacks of the conventional P&O. This paper also discusses typical Solar MPPT system, including the pros and cons of each part of the system.
