RENEWABLE ENERGY AND POWER POTENTIAL MAPPING IN VIETNAM USING SATELLITE-DERIVED AND GIS-BASED INFORMATION
Energy is the lifeblood of modern economies, which are powered by energy demand for production and consumption in everyday life. The twenty-first century has been designated the "age of green economic development," as it has seen fresh development and incredible improvements in technologies for producing energy from infinite sources of renewable energy found in the natural world.
Driven by the fossil fuel depletion rate forecast over the next 100 years and the dire warnings on the projected impact of climate change, Vietnam has identified energy security and sustainable energy development as indispensable elements in the country's strategic path toward sustainability in the coming century. The Vietnamese government has demonstrated their commitment to priorities in ensuring national energy security, providing stable, high-quality, and affordable energy supply for sustainable socio-economic development by issuing and adopting a strategic orientation for sustainable energy development through 2030 and vision to 2045.
To begin with, a geographic information system (GIS) is a computer program that captures, stores, checks, and displays data about locations on the Earth's surface. GIS can display a wide range of data on a single map, including streets, buildings, and plants. This allows people to identify, evaluate, and comprehend patterns and correlations more quickly. For addressing where and how to support sustainable energy activities, GIS has become a vital planning and management tool. Geographic Information Systems (GIS) have been used for combining the green energy potential with the land availability according to each scenario to deliver the technical renewable energy potential maps of Vietnam.
In Vietnam, solar energy could be considered as one of the most ubiqutous green energies which are used in many household’s daily lives. Therefore, in this essay, it will show further information about the solar energy mapping in Vietnam using GIS-based information. Solar radiation is the most important consideration when installing PV or CSP plants. Thus, it is necessary to identify areas where solar radiation is abundant and to predict the spatial and temporal distribution of solar radiation for effective solar resource utilization. GISs are very useful in spatial and temporal analyses of solar resources while implementing location-specific technologies. We will present the mapping of solar radiation components that has been calculated from satellite-derived data combined with solar radiation derived from sunshine duration and other additional sources of information based on reanalysis for several atmospheric and meteorological parameters involved. Two scenarios have been selected for the study of the solar potential: CSP Parabolic Trough of 50 MWe and grid-connected Flat Plate PV plant of around 1 MWe. For each selected scenario plant performance simulations have been computed for developing simple expressions that allow the estimation of the solar potential from the annual solar irradiation and the latitude of every site in Vietnam. Finally, Geographic Information Systems (GIS) have been used for combining the solar potential with the land availability according to each scenario to deliver the technical solar potential maps of Vietnam.
