The invention discloses a distributed energy optimization control method in a power grid with uncertain power, which comprises the following steps: S1, optimizing and calculating initial parameters; S2, acquiring information of users accessed to distributed power supplies, and performing optimization calculation by adopting a distributed algorithm according to the requirement of an objective function; S3, adjusting the generating capacity of the local distributed power supplies according to the optimization result to obtain an accurate optimization result; and S4, fitting a change curve of a local optimal point according to the accurate optimization result, calculating a predicted value of the optimal point according to the characteristic trend of the curve, and carrying out unscheduled local adjustment according to the predicted value. By carrying out analysis according to the characteristic law of the optimization points and utilizing the inertia of control and scheduling, the communication and management cost is saved on the premise of keeping the accuracy and rapidity of control and optimization.
Description
Technical field [0001] The invention relates to a distributed energy optimization control method in a power grid with uncertainty, and belongs to the technical field of grid control. Background technique [0002] With the large number of new energy sources, especially distributed photovoltaic power sources, being connected to the power grid, the characteristics of the power flow of the power grid have changed, and the distributed power sources connected to the power grid must be effectively managed and dispatched. In addition, the operating cost of the power grid should also be considered, and the user's cost should be as low as possible. Therefore, in the context of the continuous development of today's power grids and the large number of distributed power sources, the consideration of the cost of power grid users has become an important issue that needs to be considered in operation and dispatch. [0003] The Chinese patent with the patent number 201810024408.0: "A genetic algor...
