Abstract

The invention provides a distributed power supply peak regulation capacity optimization method. An annual load duration curve is drawn according to an annual load curve, and a distribution network is planned under the next peak regulation load level of the maximum load. Therefore, the distributed power supply peak regulation capacity optimization method provided by the invention is used for reducing the investment funds and improving the equipment utilization rate.

Description

technical field [0001] The invention proposes a distributed power supply peak-shaving capacity optimization method, which belongs to the field of distribution network peak-shaving. Background technique [0002] According to the statistics of the National Electric Power Dispatching and Communication Center, the peak load of power grids in various regions of my country has increased by more than 10%, but the increase in low-peak load has not exceeded 5%, and there is even a phenomenon of negative growth in low-peak load. According to the peak-valley analysis of the minimum daily load rate in a certain area, the average minimum daily load rate in summer is 0.561, and 0.59 in winter, and the peak-valley difference reaches 25GW. In other words, the load peak-to-valley difference is getting bigger and bigger, and the task of peak load regulation is arduous. It is urgent to consider peak load control in grid planning, which is conducive to the healthy development of the grid. [0...
