Global Electricity Trade Network: Structures and Implications
نویسندگان
چکیده
Nations increasingly trade electricity, and understanding the structure of the global power grid can help identify nations that are critical for its reliability. This study examines the global grid as a network with nations as nodes and international electricity trade as links. We analyze the structure of the global electricity trade network and find that the network consists of four sub-networks, and provide a detailed analysis of the largest network, Eurasia. Russia, China, Ukraine, and Azerbaijan have high betweenness measures in the Eurasian sub-network, indicating the degrees of centrality of the positions they hold. The analysis reveals that the Eurasian sub-network consists of seven communities based on the network structure. We find that the communities do not fully align with geographical proximity, and that the present international electricity trade in the Eurasian sub-network causes an approximately 11 million additional tons of CO2 emissions.

متن کاملThe Application of Complex Networks Analysis to Assess Iran's Trade and It's Most Important Trading Partners in Asia
The existing trade models suggest that for tradable goods potential partners can be many, but eventually only one (the one offering the best price) should be selected, therefore relatively few (unidirectional) trade links will appear between countries. If the structure of international trade flows describes as a network, trade link would give rise between countries. This paper exploit recently-...
متن کاملPredicting Crisis in the Global Trade Network
The web of international trade relationships is a natural domain in which to apply the discipline of network analysis. Network analysis can reveal insights into the structures of trade relationship and interdependencies between trade partners that are not immediately evident in a straight out statistical analysis of trade data.

متن کاملEstimating multi-period global cost efficiency and productivity change of systems with network structures
The current paper develops three different ways to measure the multi-period global cost efficiency for homogeneous networks of processes when the prices of exogenous inputs are known at all time periods. A multi-period network data envelopment analysis model is presented to measure the minimum cost of the network system based on the global production possibility set. We show that there is a rel...
