Abstract

The invention discloses a distributed energy optimization control method in an uncertain power grid, comprising the following steps: step 1, optimizing and calculating initial parameters; It is required to use distributed algorithms for optimization calculation; step 3, adjust the power generation of local distributed power sources according to the optimization results, and obtain accurate optimization results; step 4, fit the change curve of the local optimal point according to the accurate optimization results, according to the characteristics of this curve Trending computes optimum point forecasts and makes local adjustments based on the forecasts without scheduling. The present invention analyzes the characteristics and rules of optimization points, utilizes the "inertia" of control and scheduling, and saves communication and management costs on the premise of maintaining the accuracy and rapidity of control and optimization.

Description

Technical field [0001] The present invention relates to a distributed energy optimization control method in an uncertain power grid, belonging to the field of power grid control technology. Background technique [0002] As new energy sources, especially distributed photovoltaic power supplies in the grid, the power grid fashion characteristics have changed, and the distributed power supplies accessed in the grid must be effectively managed. In addition, we must consider the operating cost of the grid, and pursue user costs as low as possible. Therefore, in the context of the continuous development of today's power grid and the large-scale access to the distributed power supply, the consideration of the user cost of the grid is an important issue that needs to be considered in operation and scheduling. [0003] Patent No. 201810024408.0 China Patent: "A Method for Optimization of Genetic Algorithm With Distributed Power Supply Power Supply Network", which discloses a distributed p...
