Embodiment 1

[0087] The present invention provides a schematic flowchart of a flexible interaction method for a virtual power plant based on a general markup extension model. The method is applied to a control center of a virtual power plant, such as figure 1 As shown, the method includes:

[0088] Step A1: After the control center of the virtual power plant (ie VPP) receives the power update command issued by the control center of the distribution system operator (ie DSO), the control center of the virtual power plant obtains the composition based on the pre-built general markup extension model. Power and cost information of each equipment of VPP;

[0089] Step A2: Based on the power and cost information of each device, the control center of the virtual power plant sends the available power and estimated cost of the specified time period to the control center of the distribution system operator;

[0090] Step A3: the control center of the virtual power plant obtains the dispatch plan iss...

Embodiment 2

[0116] The present invention also provides a control center of a virtual power plant based on the universal markup extension model, such as figure 2 As shown, the control center includes: a data acquisition module, a commitment uploading module, and a scheduling forwarding module;

[0117] The data acquisition module is used to acquire the power and cost information of each device constituting the VPP based on the pre-built universal markup extension model after receiving the power update command issued by the control center of the DSO;

[0118] Commitment upload module, which is used to send the available power and estimated cost of the specified time period to the control center of the DSO based on the power and cost information of each device;

[0119] The dispatching and forwarding module is used to obtain the dispatching plan issued by the control center of the DSO, and dispatch the dispatching plan based on the general markup extension model;

[0120] Among them, the g...

Embodiment 3

[0130] The present invention also provides a flexible interaction method for a virtual power plant based on the general markup extension model, which is applied to the equipment controller of the virtual power plant, such as image 3 As shown, the method includes:

[0131] Step B1: The device in the VPP receives a power update command based on a pre-built generic markup extension model;

[0132] Step B2: The device uploads power and cost information based on the generic markup extension model;

[0133] Step B3: The device receives the scheduling plan based on the general markup extension model, and executes the scheduling plan;

[0134] Among them, the general markup extension model includes: the XMPP server corresponding to the VPP, the XMPP client respectively set in the control center of the VPP and each device, the TLS link between the XMPP server and the XMPP client, and the rules for mapping interactive information into XML ; Interactive information includes: power upd...

Abstract

The invention provides a virtual power plant flexible interaction method and system based on a universal mark expansion model, and the method comprises the steps: enabling a control center of a virtual power plant to interact with all devices forming a virtual system based on a pre-built universal mark expansion model, the universal marking extension model comprises an XMPP server corresponding to the virtual power plant, XMPP clients arranged on a control center and each device of the virtual power plant, negotiation encryption protocol links between the XMPP server and the XMPP clients, and a rule for mapping interaction information into an extensible marking language; the interaction information comprises a power supply updating command, power and cost information and a scheduling plan. According to the method, the interaction information is mapped into the extensible markup language, so that information interaction forms among resources of different operators are unified, and the expandability of a virtual power plant network is achieved; the security problem of the virtual power plant is solved by using the negotiation encryption protocol link to transmit the interaction information.

Description

technical field [0001] The invention belongs to the technical field of virtual power plant communication, and in particular relates to a flexible interaction method and system for a virtual power plant based on a universal markup extension model. Background technique [0002] Virtual Power Plant (VPP) is based on advanced information and communication technology, realizes the efficient interconnection of various types of user loads, distributed photovoltaics, distributed energy storage and other demand-side resources, and participates in power grid regulation through distributed and dynamic aggregation management modes Trading with the power market and ultimately realizing the efficient integration and optimization of resources is an important realization path for building a new power system with new energy as the main body. Optimum coordination and interaction between distributed generation equipment (DER), controllable loads and energy storage equipment (ESD) through an ef...
