Embodiment Construction

[0059] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0060] Aiming at the existing problems, the present invention provides a centralized control method for generalized source-storage system scheduling. In the present invention, a concept of a generalized energy storage system is proposed: the generalized source-storage system is a unified scheduling and linkage system constructed of time-space dispersion, multiple types of energy storage and multiple types of new energy. The economical energy storage system formulates a flexible and interactive operation strategy, shifts and concentrates the scattered power of new energy to the peak load period, so that it can closely track the load change of the power grid, so as to reduce thermal power installed capacity, reduce system operating costs, and reduce The pu...

Abstract

The invention provides a centralized control method for generalized source-storage system scheduling. The centralized control method for generalized source-storage system scheduling includes the following steps: step S1, determine the generalized source-storage system; step S2, determine the constraint range of the traditional power supply unit according to the operation status of the traditional power supply system; step S3, according to the energy storage system The optimal mathematical model of the generalized source-storage system under the constraints of schedulable space is established; step S4, the optimal mathematical model is solved, and the output includes the output curve of each unit, the total cost of operation, the operation status of energy storage, and the waste of new energy. information, and applied to the generalized source-storage system. The invention solves the problem of optimal dispatching of new energy high-permeability power systems, and achieves the goals of reducing thermal power installed capacity, reducing system operating costs, and reducing waste water and new energy.

Description

technical field [0001] The invention relates to the technical field of new energy penetration power systems, in particular to a centralized control method for generalized source-storage system scheduling. Background technique [0002] In the new energy high penetration rate system, due to the insufficient regulation ability of the traditional power supply, the phenomenon of abandoning wind and light is more serious in the operation of the power system. The random fluctuations of load and new energy and the limitations of the adjustment ability of traditional thermal power supply units often lead to the power system needing to abandon part of the new energy or cut off part of the controllable load to achieve the power balance of the power system, which also makes the new The power supply capacity and reliability of power systems with high energy penetration rates have declined. As an effective technical means to improve the utilization rate of new energy such as wind power, ...
