Problems solved by technology

However, this method cuts power proportionally according to the installed capacity of new energy instead of the real-time output of the station, which will cause inconsistency in the power cut rate of each station; secondly, this method needs to establish and solve a secondary optimization model, when the power grid When multiple complex nested section structures are included, the optimization model will have many variables and take a long time to solve, making it difficult to meet the timeliness needs of the dispatching department for power generation planning

Abstract

The invention relates to a new energy station power generation plan making method and device. The method comprises: dividing a power transmission section into multiple layers of nested sections according to the voltage level of the power transmission section; according to the power generation capacity of each limited section in each layer of nested sections and the predicted output of each sectionin each layer of nested sections, determining a peak-shaving and power-limiting power value of each section in each layer of nested sections; and determining a power generation plan of each section in each layer of nested sections by utilizing the peak regulation and power limiting power value of each section in each layer of nested sections. According to the technical scheme provided by the invention, the new energy power limiting rate of each region of the power grid can be kept consistent, and a fair distribution principle of power limiting power is realized.

Description

technical field [0001] The invention relates to the technical field of new energy scheduling operation, in particular to a method and device for formulating a power generation plan for a new energy station. Background technique [0002] Formulating power generation plans for new energy stations is an important daily task for power dispatching departments. Taking the day-ahead power generation plan as an example, the new energy station needs to report its output at 96 o'clock before the day before the day of the report every morning. Taking into account factors such as space, peak-shaving capacity, and power transmission capacity of main regional sections, formulate the day-ahead power generation plan for each new energy station. In the absence of power grid limitation, according to the provisions of my country's "Renewable Energy Law", the grid needs to fully accept new energy, that is, all new energy stations will generate power according to the predicted output; Under suc...
