Abstract

The invention discloses an energy storage scheduling method based on new energy consumption and a computer medium, and the method comprises the steps: extracting the operation data of a power grid, and building a power grid energy storage scheduling model based on the operation data of the power grid by taking the maximum combined output of wind and light power generation and the minimum operation cost of a thermal power generating unit as a target function; setting constraint conditions of the power grid energy storage scheduling model, wherein the constraint conditions comprise an energy storage device constraint condition, a power grid stable operation constraint condition and a generator set constraint condition; using a multi-objective genetic algorithm to set weights for the objective functions, converting the objective functions into single objective functions, and solving the single objective functions to obtain an optimal charging and discharging curve of the energy storage device; and determining a scheduling scheme of the energy storage device according to the optimal charging and discharging curve. According to the method, the multi-objective genetic algorithm based on the Pareto front is adopted, and the weight is introduced to convert the multi-objective function into the single-objective function, so that the situation of falling into a local optimal solution in the optimization process is effectively avoided, and the calculation speed is improved.

Description

technical field [0001] The invention relates to the field of optimal scheduling of power systems, in particular to an energy storage scheduling method based on new energy consumption and a computer medium. Background technique [0002] With the rapid increase of new energy installed capacity, the proportion of reserve capacity provided by existing conventional units is obviously insufficient, unable to take into account the consumption effect of new energy output and the stable operation of the power grid system, resulting in the abandonment of a large number of new energy output. The energy storage device has the advantages of fast response speed and flexible charge and discharge, which can make up for the shortcomings of conventional units and respond to the volatility and randomness of new energy in a timely manner, thereby promoting the consumption of new energy, reducing the benefit of power abandonment, and alleviating the large-scale merger of new energy. The peak-sha...
