Embodiment 2

[0054] A point-to-point transformer capacity mutual aid method, comprising the following steps:

[0055] S1. Install a smart terminal at the transformer. As the underlying basic measurement and control device, the smart terminal is an important link in the informatization of the distribution network. It has flexible terminal access and networking modes, and rich measurement content and data resources. Sharing, real-time synchronous measurement, control and transmission of wide-area data;

[0056] S2. Connect various energy storage components such as batteries and flexible loads to the distribution network through smart terminals; use power electronic converters in smart terminals to realize the charge and discharge control of energy storage components, and realize load capacity in combination with the control of flexible loads Optimization, making the smart terminal a highly integrated comprehensive energy control device;

[0057] S3. Complete point-to-point data transmission...

Embodiment 1

[0061] The difference between Embodiment 1 and Embodiment 2 lies in the measures taken when a breach occurs.

[0062] A flexible and flexible distribution network provides the necessary means and technical support for realizing the capacity mutual aid of transformers, involving different links at various levels such as flexible equipment, flexible scheduling and flexible transactions.

[0063] 5. Flexible interconnection of distribution network based on SOP

[0064] The intelligent soft switch SOP technology for power distribution is causing a new wave of research. Power electronic devices are used to replace traditional contact switches to form normalized soft connections, which change the traditional closed-loop design and open-loop power supply methods, and can provide flexible, fast , Accurate power exchange control and power flow optimization capabilities.

[0065] 6. Adjustable flexible load

[0066] The power load can be further subdivided according to three different...

Abstract

The invention discloses a point-to-point transformer capacity mutual assistance method. The method comprises the following steps: S1, installing an intelligent terminal at a transformer; S2, connecting various energy type energy storage elements such as a battery and the like and a flexible load to a distribution network through an intelligent terminal; S3, completing point-to-point data transmission through an intelligent terminal, orderly connecting the scattered transformers, and efficiently coordinating the collected mass data through big data and an artificial intelligence technology, sothat the transformers cooperatively output power to realize mutual aid sharing of capacities; and S5, automatically completing transaction settlement by the platform according to the judgment result of the power dispatching department and rules. For aiming at information interaction, response confirmation, transaction signing, default judgment, result accounting and the like in the platform operation process, a standardized process is formulated, supervision and control of the whole supply and demand transaction process are realized, and timeliness, reliability and safety are ensured.

Description

technical field [0001] The invention belongs to the field of electric power, and is a point-to-point transformer capacity mutual aid method. Background technique [0002] With the major changes in the energy structure and user needs, the distribution network has transformed from the traditional radial type to multi-source interconnection, and has further developed into a multi-level, multi-link, and multi-form complex network. Especially with the reform of the power trading system and the improvement of the market-oriented trading mechanism, the future distribution network will be dominated by distributed power sources, and the deep integration of information and communication technology with the energy network will meet the responsible needs of flexible load differentiation. With the participation of market players, electricity prices and forms of electricity consumption are more flexible. [0003] The current grid interaction is a strong center model. With the gradual mat...
