Abstract

The present invention provides a grid planning method based on the stochastic dual dynamic theory. The method comprises the steps of establishing a grid planning mathematical model, selecting a grid operation scene, solving a grid planning mathematical model, checking the grid operation scene, and using the stochastic dual dynamic theory to optimize the grid planning mathematical model. According to the invention, a load uncertainty and a renewable energy uncertainty are considered, the renewable energy utilization rate is considered, thus a renewable energy access requirement can be satisfied by a planning scheme, the feasibility of the grid planning in different scenes is considered, thus the planning scheme has strong robustness, the N-k safety verification is considered comprehensively, the safety operation requirement can be satisfied by the planning scheme, the SDDP theory is used to establish a grid planning mathematical model under the circumstance of uncertainty, the Bender decomposition method is employed to solve the grid planning mathematical model, and the solving difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of power grid planning, and in particular relates to a power grid planning method based on stochastic dual dynamic theory. Background technique [0002] Due to the increase of load and generation capacity year by year, it is necessary to strengthen the power grid to increase its transmission capacity, optimize line investment costs, and make it meet certain operational safety constraints. This is the problem to be solved by power grid planning. With the large-scale access of renewable energy, it is necessary to transport the renewable energy far away from the load center to the load center in the form of long-distance transmission. Due to the intermittent nature of renewable energy and the difficulty of long-distance transmission, the complexity of grid planning is increased. [0003] In the existing grid planning research, more and more studies consider load uncertainty and renewable energy uncertainty in ...
