Abstract

The invention relates to a distributed intelligent energy management method for multiple intelligent families, which belongs to the technical field of intelligent power grids and comprises the following steps of: S1, establishing a mathematical model of each component of the intelligent families; establishing a topological structure among the intelligent families in the community so as to realize energy transaction of the intelligent families; formulating an energy transaction rule between the intelligent families; s2, establishing a corresponding power battery aging model for the electric vehicle in each intelligent home, wherein the power battery aging model comprises a circulation aging model and a calendar aging model; s3, establishing an optimization target with the lowest daily electric energy cost for each intelligent home, and designing corresponding constraints of each component; s4, converting an original optimization problem into a convex optimization problem, and ensuring that the obtained solution is globally optimal; and S5, designing a consistency auxiliary variable of energy transaction among the intelligent families, and decomposing and coordinating optimization problems of the intelligent families to be optimal by using a Consensus ADMM algorithm, so that the electric energy cost of the whole community is lowest.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and relates to a distributed smart energy management method for multi-smart families. Background technique [0002] A community containing multiple smart homes is an integral part of the smart grid, and it is the development trend of the smart grid to provide functional modules for energy autonomy in local areas. Smart homes include controllable load devices, uncontrollable load devices, electric vehicles (Electric Vehicle, EV), renewable energy sources (Renewable Energy Sources, RESs) and energy storage systems (Energy Storage System, ESS). Realize a high degree of energy autonomy and greatly reduce energy costs. At present, the distributed management of multiple smart homes has become a research hotspot. Smart homes are both energy suppliers and energy consumers. Multilateral trading mechanisms can promote the development of energy autonomous communities. [0003] Traditional centralized ...
