Abstract—Solar radiation falling on earth is far more than energy demand of the world, but because of issues related to storage and economics, it is not possible to rely on it, when it comes to fulfill huge electricity demands at national level. A world super grid, connecting all the continents is reported, which is expected to avoid this need of energy storage, while powering the whole world throughout the day by transmitting excess electricity. Feasibility of such grid is determined by matching supply and demand of a particular region. World super grid will be powered by solar photovoltaic panels installed all over the world to facilitate the utilization of solar insolation. At any point of time, Sun shining area will supply electricity to that area itself along with other parts, which are in dark. Electricity demands of regions are analyzed and switching between supplying and demanding regions is modelled according to motion of the sun throughout the day. Several positive impacts of the grid such as environmental, economic and international relations are evaluated. Country preference for such grid is another key issue. Grid preference index is proposed in order to classify countries according to their preference for this grid, considering various factors such as its land area, geographical position and energy security. Policies at national and international level are recommended for smooth implementation of the grid. Elements of this analysis, which can be investigated further to make this rudimentary model more sophisticated are discussed.
Index Terms—Grid preference index, power transmission, solar photovoltaic, world super grid.
