Abstract

The invention discloses a posterior ideal plane analyzing method based on actual power grid operation data. The method comprises the following steps of: by using information, such as operation mode, load requirement, standby requirement and the like, in the power grid actual operation, as input information of power generation plane optimization, figuring out an optimal ideal dispatching plan according to a set optimization target; and comparing the difference between the ideal dispatching plan and an actual executing plan so as to evaluate an ideal dispatching optimization space. And by using the posterior ideal plane analyzing method based on the actual power grid operation data, disclosed by the invention, is used for analyzing the reasonability and effectiveness of SCUC / SCED (Security Constrained Unit Commitment / Security Constrained Economic Dispatch) model and algorithm, reflecting the instruction degree of the power generation plan to the actual production and promoting the practical and engineering applications of SCUC / SCED.

Description

technical field [0001] The invention belongs to the field of power system dispatching plan and safety check analysis, and relates to an analysis method of post-event ideal plan based on actual power grid operation data. Background technique [0002] In recent years, dispatching software centered on Safety Constrained Unit Combination / Safety Constrained Economic Dispatch (SCUC / SCED) has been successfully applied in foreign large-scale power systems and achieved remarkable benefits. Driven by the demand for energy-saving power generation dispatching, my country has also carried out in-depth research on SCUC / SCED and achieved a lot of research results. It can fully consider various power grid security constraints in unit combination and economic dispatching. Significant progress has also been made. [0003] However, the research and application of SCUC / SCED in our country is still in its infancy. There is still a lot to be done in the research of practical and efficient models ...
