Abstract

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 regional power grid new energy consumption capability improvement parameter considering the sensitivity and the cost. According to the method, the defects of sensitivity and economical efficiency of a traditional absorption capacity strategy are overcome, the improvement speed of the new energy absorption capacity of the regional power grid is improved, and the cost brought by adjusting sensitivity parameters influencing the absorption capacity is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of new energy consumption, and in particular relates to a method for improving the new energy consumption capacity of a regional power grid that takes both sensitivity and cost into consideration. Background technique [0002] Under the background of carbon peak and carbon neutrality, my country's energy transformation is accelerating, and vigorously developing new energy has become the development direction that conforms to my country's energy production and consumption revolution. By the end of 2021, the installed capacity of wind power is 328 million kilowatts, and the installed capacity of photovoltaic power generation is 306 million kilowatts, accounting for 13.8% and 12.9% of the country's total installed power generation capacity, respectively. Due to the randomness and volatility of the output of new energy sources such as wind and light, large-scale consumption has always been a worldwide problem. ...
