Distributed management system and method for residential electricity consumption load based on demand response

Abstract

The invention discloses a distributed management system and method for residential electricity consumption load based on a demand response. The distributed management method comprises the steps that optimization is carried out on energy consumption conditions of a user with an objective of enabling the expense of the user to be the minimum according to the time-of-use electricity price issued by a dispatching department, and an optimized energy consumption plan is fed back to the dispatching department; secondly, the dispatching department adds load demands of each user so as to acquire the total load at the moment and sends the total load to a first family load management system; the family load management system readjusts the load thereof according to the received total load, the adjusted total load is transmitted among the family load management systems until the load of all users is adjusted; then the total load after all users are completely adjusted is transmitted among the users again so as to complete a time of new load adjustment; and finally iteration is ended under the condition that preset given conditions are satisfied, and a final residential load arrangement result is acquired. According to the invention, a multi-objective optimization problem is converted into two single-objective optimization problems, thereby realizing an optimization objective with a small data amount.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a distributed management system and method for residential electricity loads based on demand response. Background technique [0002] With the development of smart grid technology, it is possible to use demand response technology to further tap the energy-saving potential of demand-side energy-using systems. As an important means of peak shaving and valley filling, demand response technology can realize real-time voltage control and improve power quality. At the same time, demand response is also one of the important ways to achieve energy saving and emission reduction. [0003] The current demand response technology at home and abroad is still immature, and unreasonable demand management methods may cause dissatisfaction among users, and even lead to situations that are harmful to the power grid, such as anti-peaking. Moreover, the current demand response resea...
