In order to realize peak shaving and reduce the cost of household electricity consumption

it is necessary to guide the household electricity load more reasonably.In this paper

according to the continuity and discontinuity of household electricity load and the relevance

order

strong dependence and other characteristics among household electricity load

in the background of time-of-use price

a smart household power consumption system model is built including the load model

the storage battery model and the economic optimization model.A method is presented to transform the optimization problem into a mixed integer linear programming problem by encoding of the decision variables model using 0-1 variables.The problem can be solved by Gurobi programming software

which greatly reduces the difficulty of solving the problem.In the Matlab environment

the simulation of the household electricity load data is carried out.The simulation result shows that the model and the optimization strategy can realize the transfer of household electricity load and reduce the cost of electricity.
