Problems solved by technology

Traditional power grid planning does not take into account the differences in power supply construction cycles, the timing of power grid construction investment, and the coordination between planning and operation, making it increasingly difficult to adapt to the new situation of source-load diversification.

Abstract

The invention discloses a transmission network planning progressive optimization method, which comprises the following steps: according to load forecasting values of each time scale in the power network data planning time period, schemes of different forms of power sources in the planning time period, and candidate power network elements and path schemes of the power network planning are planned;an evolutionary optimization model for transmission network planning is built, which takes into account the variable time interval operation and investment coordination in multiple stages of power network development, the objective of the model is to minimize the sum of the investment cost and the operation cost of the transmission network in the planning cycle, and includes constraints; the constraint conditions in the optimization model are transformed into a mixed integer linear programming model which is easy to solve, and the mixed integer linear programming method is used to solve the optimization model, and the final transmission network planning scheme is obtained. The method can be used in transmission network planning and decision-making under the background of large-scale development of different forms of power generation, is conducive to promoting the coordination of power network planning and operation, and improves the accuracy of power network planning scheme.

Description

technical field [0001] The invention relates to the technical field of power grid planning, in particular to a progressive optimization method for power grid planning. Background technique [0002] Large-capacity feed-in of UHV AC and DC, explosive growth of renewable energy, and complex and changeable power load characteristics are the main influencing factors facing the clean and coordinated development of power grids in the new era, which put forward higher requirements for power grid planning technology. Facing unprecedented challenges, there is an urgency to adapt to the development of the situation and continuously improve and improve. Traditional grid planning does not take into account the differences in power supply construction cycles, the timing of grid construction investment, and the coordination between planning and operation, making it increasingly difficult to adapt to the new situation of source-load diversification. [0003] Considering the timing of grid ...
