Abstract

The invention discloses a distributed and centralized collaborative micro-grid group scheduling method. The method comprises the following steps: acquiring day-ahead prediction data of photovoltaic and load in each unit of a park micro-grid group; constructing a park micro-grid group plan scheduling model, and performing solving to obtain a plan scheduling result of the micro-grid group; calculating the difference between the real-time operation state data of each device and each load of the microgrid group in the park and the planned scheduling result of the microgrid group to obtain the overall real-time net electric power deviation of the park; calculating real-time net electric power deviation shared by each unit of the park, constructing a real-time optimization scheduling model of each unit, and solving the real-time optimization scheduling model of each unit to obtain a real-time power reference value of each unit microgrid of the park; and issuing the solved real-time power reference value to each micro-grid unit to complete single-time optimal scheduling of the micro-grid group, and repeatedly executing the steps in a running day to complete daily running scheduling of the micro-grid group. According to the method, the difference benefit maximization of the whole micro-grid group is achieved, and the economic requirements of global development of the current power grid are met.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and in particular relates to a distributed and centralized micro-grid group scheduling method. Background technique [0002] Under the background of smart grid, the park microgrid group has become an important development trend of microgrid and an effective form of energy comprehensive utilization, including multiple types of energy supply and consumption units, such as single microgrid, intelligent users with distributed power, traditional users , electric vehicle charging piles, etc. These units may have different self-management capabilities, information security requirements, or self-management willingness, so it is necessary to adopt differentiated scheduling strategies for diverse user management. For example: single micro-grid, smart buildings, etc., have independent energy management systems, which can be independently dispatched and managed. This type of unit can adopt a distributed...
