marginal benefit
3.It was estimated that a potential increase uptake CO 2 capacity would be about 1×Gt C a -1 for the Arctic Ocean due to a long solar radiation and high biological production in the marginal regions in summer would drive a biological pump to effectively absorb the atmospheric CO 2. The deep sea circulation and ventilation would also benefit to transfer CO 2 from surface water to deep sea water.
4.A example of IEEE6-bus system is tested by using new Power System Analysis Toolbox (PSAT), The results obtained show that the proposed technique is able to improve electric power system security while yielding better market benefit through increased total transaction amount and improved locational marginal prices.
