Abstract

The invention relates to a multi-target optimized energy management information processing method for a virtual power plant. The method comprises the following steps of: 1) acquiring power generation information of power supplies administered by a virtual power plant company and power utilization information of power utilization users, determining credits of users according to the acquired power generation and power utilization information and the historical information of the power supplies and the users, and determining the regulating ranges of power generation quantity and power utilization quantity according to the credits by using a fuzzy function; 2) constructing a multi-target united scheduling model; 3) substituting the power generation information and the power utilization information acquired in the step 1) into the multi-target united scheduling model with a priority in the step 2), and solving with an optimization algorithm; and 4) performing multi-target optimization and priority coordinating processing. Compared with the prior art, the method has the advantages of effective optimization and management of an assembly of a distributed generator and a controllable load and the like.

Description

Technical field [0001] The invention relates to an energy management information processing method, in particular to a multi-objective optimized energy management information processing method for virtual power plants. Background technique [0002] With the development of smart grid technology, virtual powerplants (VPP) have gained attention as an intelligent dispatching method that realizes the interaction between power grids, power sources, and users. A virtual power plant is a collection of a certain number of distributed generators and controllable loads supervised and optimized by a distributed power management system. It has load forecasting, renewable energy generation forecasting, unit composition, power generation and load management, and exchange monitoring. Need function. VPP is a collection of small and ultra-small decentralized generator sets supervised and controlled by EMS. Its owners and operators can obtain technical, economic and ecological information through ...
