Regional power grid new energy consumption capability improvement method considering sensitivity and cost

The invention relates to a new energy consumption technology, in particular to a regional power grid new energy consumption capability improving method giving consideration to sensitivity and cost, which comprises the following steps: obtaining a relational expression between the regional power grid consumption capability and each sensitivity parameter of a load rate, a reserve rate, a thermal power generating unit peak regulation rate and a new energy penetration rate based on electric quantity balance equality constraints; determining a target function considering the improvement sensitivity and cost of the absorption capability of the regional power grid through a parameter sensitivity matrix and a sensitivity parameter adjustment cost matrix related to the absorption capability of the new energy of the regional power grid, and establishing a mathematical model by taking the improvement of the cost performance of the sensitivity as a target in consideration of constraint conditions; and solving to obtain a
