电热水器与变频空调负荷群的联合调度控制

针对能源互联网中的需求侧响应要求,为使家庭负荷响应电力系统功率波动,提出一种基于电热水器与变频空调负荷群的联合调度控制策略。分析电热水器与变频空调作为备用的优势,并建立其响应聚合模型;结合负荷特点,在考虑变频空调负荷群多样性的基础上提出先调电热水器再调变频空调的联合控制策略;结合负荷调度曲线,设定调度死区,对所提调度控制策略进行仿真,验证了所提控制策略在功率调度中应用的有效性,并说明增加负荷数量可以显著提高负荷响应功率调节能力。

Joint dispatch control of electrical water heater and inverter air conditioner load group

For the demand response requirements of the energy internet, a joint dispatch control strategy based on the electric water heater and the inverter air conditioner load group were proposed in order to make the household load response to grid power fluctuation. The advantages of electric water heater and inverter air conditioner as power dispatch backup were explained and the response aggregation model was established. Combining the load characteristics, a joint dispatch control strategy which adjusted the electric water heater firstly and the inverter air conditioner secondly was proposed based on the consideration of the diversity of inverter air conditioner load group. The scheduling dead zone was set based on load dispatch curve to simulate the proposed dispatch control strategy, the effectiveness of the proposed control strategy in power dispatch was verified, which showed that increasing the number of loads could significantly improve the load response of power scheduling ability.
