The existing quantity of on-grid electricity of electricity suppliers is mainly determined according to the proportion of its generation capacity, but the on-grid electricity tariff is the unified benchmark price. Based on the principle of minimum total generation cost under the constraint of carbon emissions, this paper designs the allocation mechanism of on-grid electricity quantity and its tariff mechanism in oligopoly power market, and makes a comparison with the existing on-grid electricity mechanism. The results show that: (1) the new ...
