Method and device for measuring and calculating operation reserve capacity and computer

Abstract

The invention belongs to the technical field of computers, and particularly relates to a method and device for measuring and calculating operation reserve capacity and a computer, and the method comprises the steps: obtaining historical data of the operation reserve capacity; predicting error statistics according to the operation reserve capacity historical data to obtain an error statistics result; according to the error statistical result and the predicted net load fluctuation statistical result, obtaining loss data caused by insufficient reservation of the operation reserve capacity; constructing a target function according to the loss data caused by the insufficient reservation of the operation reserve capacity and the expected cost; and according to the objective function and the constraint condition, measuring and calculating the operation reserve capacity. The influence of current large-scale access of new energy on power grid operation uncertainty is considered, an operation reserve distribution framework considering dual uncertainty is provided, loss possibly caused by insufficient operation reserve capacity and cost for providing the operation reserve capacity are considered, and an expected comprehensive benefit is maximized as a target. And the operation reserve capacity can be predicted more accurately.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method, a device and a computer for measuring and calculating the running reserve capacity. Background technique [0002] Operation reserve is a necessary power auxiliary service resource for power grid dispatching operation. The purpose of reserve operation reserve in dispatch operation is to deal with the influence of uncertain factors such as load demand and new energy output fluctuations in the real-time operation process, power transmission and transformation equipment failure outage, etc. . [0003] In the actual operation of the current power grid, the operating reserve capacity is mainly formulated according to the national "Technical Guidelines for Electric Power Systems". Operation reserve includes two parts: load reserve and emergency reserve. According to the requirements of "Technical Guidelines for Power Systems", load reserve is 2-5% of the maximum...
