Abstract

The invention discloses a modeling method of a uniform interface for accessing distributed energy sources into an active power distribution system. A model built by the method comprises an output interface and an input interface, wherein the information transmitted to a control system by distributed energy source equipment and an energy storage device is appointed by the output interface, and the information and action flow transmitted to the distributed energy source equipment and the energy storage device by the control system are appointed by the input interface. The method has the following outstanding effects: 1. a uniform interface model is built so that the controller of the active power distribution system adopts a uniform management mode and the control algorithm is simplified; 2. only interface information is transmitted, so that the data acquisition quantity is reduced and the communication efficiency is enhanced; 3. due to the distributed calculation mode, the calculation efficiency is enhanced; 4. by the uniform interface, a foundation is laid for the plug-and-play use of the equipment.

Description

technical field [0001] The invention relates to the field of active power distribution systems, in particular to the unified interface modeling of distributed energy and energy storage devices connected to active power distribution systems. The invention proposes a unified interface modeling of distributed energy access to active power distribution systems method. Background technique [0002] Since distributed energy and energy storage devices are connected to the distribution network, the distribution network is no longer a traditional passive distribution network. The future distribution system is a distribution system with a flexible structure that can be actively controlled and managed. Therefore, It is called active power distribution system. The purpose of developing the active power distribution system is to improve the acceptance of renewable energy, improve the utilization rate of distribution network assets, delay the upgrading investment of the distribution netw...
