Abstract

The invention discloses a source network load planning method for improving system security and coordination. The source network load planning method comprises the following steps: step 1, determininga source network load system structure; step 2, evaluating the coordination between the power supply side and the power grid side of the source network load system by utilizing the source network synergy factor, and improving the power grid N-1 security by utilizing three safety margin indexes; step 3, establishing a coordination objective function and a safety objective function, and establishing a multi-objective planning model in combination with an economic objective function; step 4, processing the uncertainty in the multi-objective planning model; step 5, solving the multi-objective planning model by adopting a multi-objective bacterial population drug tendency algorithm; and step 6, determining examples and characteristic parameters of the examples to carry out simulation analysis.The optimal economy, safety and coordination are taken as targets, the source network planning model is established, the coordination capability of the source network and the safety of the power gridcan be effectively improved, the system economy is ensured, and the problem of high uncertainty caused by the fact that the distributed power supply is connected to the power grid is reduced.

Description

technical field [0001] The invention belongs to the technical field of active distribution network planning, and in particular relates to a source network load planning method for improving system safety and coordination. Background technique [0002] In recent years, with the reduction of energy and the deepening of the concept of energy conservation and emission reduction, distributed generation has been widely used in the power industry, and distributed generation (DG) represented by wind power and photovoltaics has been widely used. In order to solve the uncertainties caused by uncontrollable distributed power generation when connected to the power grid, active distribution network technology emerged as the times require, which can effectively regulate the power flow of the system and realize active management and active control. [0003] As an important part of the active control of the active distribution network, the energy storage device can balance the random fluctu...
