Abstract

The invention discloses to a primary-secondary collaborative planning method considering a power grid full-cost chain, and belongs to the technical field of the power grid planning and distributed energy planning. The method comprises the following steps: firstly collecting power grid planning basic data and distributed energy planning basic data, and then respectively establishing a primary network layer optimization planning model, a full-cost chain computation model and a user distributed energy optimization planning model; iteratively solving three models in order so as to respectively obtain whether a to-be-selected circuit is a variable value of invest in construction, the distributed wind-power equipment is the variable value of the investment, the distributed photovoltaic equipmentis the variable value of the investment and the distributed energy storage equipment is the variable value of the investment, thereby finally obtaining a primary-secondary collaborative planning result. The power grid panning fixed cost and the power grid operation cost are shared through a power flow tracing method, the power grid secondary-primary collaborative planning is realized through theformed full-cost chain, and the power grid planning is optimized.

Description

technical field [0001] The invention belongs to the technical field of power grid planning and distributed energy planning, and in particular relates to a master-distribution collaborative planning method that takes into account the entire cost chain of the power grid, and is used for distributed energy to improve the optimization level of power grid planning. Background technique [0002] Power grid planning is based on load forecasting and power supply planning to determine when and where to invest and build what type of transmission lines and the number of circuits to achieve the required transmission capacity within the planning cycle and meet various technical indicators. Optimizing grid planning investment under the premise. [0003] Distributed energy planning refers to determining the installation location and configuration capacity of distributed energy on the basis of known load forecast results and distribution network operating conditions, so as to optimize the e...
