摘要

了实现电网削峰填谷、节约居民用电成本的目的，需要对家庭用电负荷进行更加合理的引导。综合考虑家庭用电负荷的连续性、可中断性以及负荷之间的关联性、顺序性、强依附性等特性，以分时电价为背景，建立了计及储能系统的家庭智能用电系统模型，包括负荷运行模型、蓄电池充放电模型和经济性优化模型。提出利用0—1变量对模型决策变量进行编码，将优化问题转化为混合整数线性规划问题，并采用Gurobi数学规划软件包求解，大大降低了问题的求解难度。在Matlab环境下，对家庭用电负荷数据进行仿真计算，仿真结果表明，模型和优化策略能够实现转移家庭用电负荷以及降低用电费用的目的。

Abstract

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.
