摘　　要：分时电价是电能商品的市场反应,可引导用户的用电时段,削峰填谷,提高电能的利用率,结合智能电力需求响应(DR)技术构建家庭负荷优先级(HLP)控制系统,能有效提升用户侧电网的响应能力。首先,结合家居设备的负荷特性对其进行建模;然后,保证用户舒适度,提出了一种家庭负荷优先级(HLP)控制系统算法,该算法根据优先级顺序执行负荷控制决策,并保证家庭总功耗不超过功率限定值。最后,进行算例仿真,对比不同功率限定值下各负荷运行状态,结合分时电价理论验证了HLP控制方案的有效性。The time-of-use price(TOU)responds well to the market,which can guide customers to consume electricity in a certain period of time and thus achieving peak load shifting and increasing the efficiency of electricity utilization.Combined with intelligent power demand response(DR)technology,the household loads priority(HLP)control system can effectively improve the responsiveness of user side grid.Firstly,the modeling of household appliances is conducted based on their load characteristics.Secondly,a household loads priority(HLP)control algorithm is proposed to make customers feel comfortable.The algorithm performs load control decisions according to priority order and guarantees that the total household power consumption is kept below peak-power limitation.Finally,a sample simulation is carried out to compare the status of each load operation under different power limitation,and the effectiveness of HLP control scheme is verified by combining the TOU theory.
