Embodiment Construction

[0081] The specific embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the implementation cases in the present invention, all other implementations obtained by those skilled in the art without making creative efforts.

[0082] like figure 1 As shown, the resource aggregation potential evaluation method of the source-network-load-storage coordination and interaction scheme based on hierarchical analysis includes the following steps:

[0083] Step 1 Determine the evaluation indicators by analyzing the role that various resources in the source-network-load-storage can play in the process of coordinated regulation;

[0084] The power grid architecture can be regarded as a controllable resource, which plays an increasingly important role in the case of a large number of distributed...

Abstract

The invention discloses a resource convergence potential assessment method and a device based on a source-network-load-storage collaborative interaction scheme, and the method proposes seven evaluation indexes including system comprehensive peak regulation capability, energy storage response capability, reactive power support capability, voltage stability margin, distributed energy permeability, load peak-valley difference, distributed energy consumption rate, distributed energy utilization rate and load resource utilization rate, from the three aspects: the coordination control capability, the resource interaction capability and the resource utilization capability of a source-network-load-storage system, and establishes a three-level comprehensive evaluation model by adopting an analytic hierarchy process to evaluate the convergence potential of the source-network-load-storage collaborative interaction scheme on the four types of resources. By using the method of the invention, a scheduling scheme of a certain regional power grid under different participation conditions of four types of controllable resources of source network load storage is evaluated, a decision reference is provided for planning of the regional power grid and optimization of a source network load storage collaborative interaction scheme, and the operation level of the power grid is improved.

Description

technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to a resource aggregation potential evaluation method and device based on a source-network-load-storage collaborative interaction scheme. [0002] technical background [0003] In recent years, with the rapid growth of my country's economy, the demand for electricity is increasing day by day. The traditional method of relying on the source to follow the load and increasing the investment in power construction to deal with the power shortage can no longer meet the needs of economic growth. Therefore, it is necessary to adopt a new energy supply model, make full use of unplanned power sources, and increase the proportion of clean energy. The concept of "source-grid-load-storage" collaborative interaction came into being. The collaborative interaction of "source-network-load-storage" aims to establish a new energy network, which organically combines the links of source ...
