Abstract

The invention provides a power transmission network planning scheme generation system and a method considering maintenance under new energy access. The power transmission network planning system comprises a data acquisition device which is used for acquiring the power transmission capacity of a line with a preset length, a unit operation scene associated with the line with the preset length, and the output and wind curtailment quantity of a load period in a corresponding scene; a data processor which comprises a model construction module, and is used for comprehensively considering annual lineinvestment cost, line maintenance cost, unit operation cost and wind curtailment punishment cost, constructing a power transmission network planning and maintenance joint optimization model taking the minimum annual comprehensive cost as an optimization target, and storing the power transmission network planning and maintenance joint optimization model into a model library; a model solving modulewhich is used for calling the power transmission network planning and maintenance joint optimization model, introducing related constraint conditions of state variables of line maintenance, solving the power transmission network planning and maintenance joint optimization model and outputting a planning scheme and a maintenance scheme of the power transmission network; and a display terminal which is used for displaying the planning scheme and the maintenance scheme of the power transmission network.

Description

technical field

[0001] The disclosure belongs to the field of power system transmission network planning, and in particular relates to a system and method for generating a transmission network planning scheme considering maintenance under the access of new energy. Background technique

[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] Transmission network planning is one of the basic contents of power system planning. A reasonable and effective power network is an important guarantee to ensure the balance of power supply and demand and the safe and economical operation of the system. The main goal of transmission network planning is to determine when, where and how much transmission capacity should be expanded based on the forecast of load growth trend and power supply construction plan within the planning cycle, so as to realize the optimization and adjustment ...
