摘要：

提出一种考虑分时电价的含光伏发电的智慧家庭能量调度方法。在考虑光伏输出的条件下，基于分时电价(time-of-use pricing，TOUP)，建立计及功率可调节家用电器的智慧家庭日前能量调度用户收益最大化数学模型，并考虑了家庭与电网之间双向收益方程。基于线性变换技术，将智慧家庭能量调度的混合整数规划模型转化为线性规划模型，可求得最优解；研究智慧家庭与电网之间的最大交换功率和功率可调节电器之间的协调配合对智慧家庭收益的影响。典型算例的结果验证了该模型和方法的有效性和实用性。

Abstract:

An energy scheduling method of smart home integrated with photovoltaic (PV) generation units under time-of-use pricing (TOUP) was proposed. Based on TOUP and PV generation output, the mathematical model of day-ahead energy scheduling to obtain maximal gains for smart home was established considering the appliances with adjustable power. The bilateral gains equations of smart home and the grid were incorporated in the proposed model. Based on linear transformation method, the proposed mixed integer programming model was reformulated as a linear programming one, which made it easy to obtain optimal solution. The influence of maximal exchange power and controllable appliances on gains of smart home was also studied. Test results verified the effectiveness and practicability of the proposed model and method.

Key words: energy scheduling of smart home, photovoltaic generation, day-ahead energy scheduling, time-of-use pricing, linear transformation method
