Embodiment 1

[0058] like figure 1 As shown, a source-network-load-storage collaborative optimization method based on consensus algorithm includes the following steps;

[0059] S1; Establish a "source-grid-load-storage" optimal dispatching model: firstly establish grid active power balance constraints, then establish a power source model, load model, and energy storage model, and finally establish a "source-grid-load-storage" optimization Scheduling model;

[0060] S2: Establish a collaborative optimization strategy based on the consensus algorithm: update the marginal cost of each agent, update the output power of each agent, update the local mismatch amount locally, and update the local mismatch amount again after obtaining neighbor information.

[0061] The process of establishing grid active power balance constraint, power source model, load model and energy storage model in step S1 is as follows;

[0062] Establish grid active power balance constraints:

Abstract

The invention belongs to the technical field of power transmission scheduling, and particularly relates to a consistency algorithm-based generation-grid-load-storage collaborative optimization method.The method comprises the following steps of building a "generation-grid-load-storage" optimization scheduling model; and establishing a consistency algorithm-based collaborative optimization policy.The characteristics of coordinated interaction between power supplies, between the power supplies and grids and among the grids, loads and storage are comprehensively considered, and the "generation-grid-load-storage" coordinated interaction is adopted, so that a running mode and a technology of energy resource maximum utilization are realized, and the generation-grid-load-storage collaborative optimization problem is efficiently solved through a consistency algorithm. The method realizes real-time power balance while ensuring system running economy and maximizing social welfare, realizes maximum utilization of recyclable energy, reduces abandoned wind and light, and implements a green energy-saving scheduling concept.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission scheduling, and in particular relates to a source-network-load-storage collaborative optimization method based on a consensus algorithm. Background technique [0002] In terms of coordinated optimal scheduling of source-grid-load-storage at the transmission network level, although some studies have been carried out in terms of source-source, source-grid, and grid-load-storage, the power transmission system that fully considers the four elements of source Grid-level active power dispatching strategies have not been fully studied. In the future, large-scale grid-connected renewable energy, energy storage, and demand-side response will bring challenges to the existing dispatching model, including the implementation of real-time active power dispatching control strategies for the two-sided uncertainty of the power source and load, and enhanced The ability of the system to deal wit...
