中文摘要:

      居民电热水器是一种典型的热储能负荷，用电产生的热水具有热存储性，可以消纳波动性风电。提出了用于消纳风电的电热水器负荷群滑模控制策略，来实时控制电热水器负荷群。控制率与电热水器群数量、热水使用情况等相关，对于消纳风电具有较强的鲁棒性。采用某城区居民区电热水器负荷群的仿真研究表明，提出的电热水器群滑模控制策略能有效消纳风电，验证了电热水器负荷群滑模控制策略有效性。

英文摘要:

      Residential electric water heater is a typical thermal energy storage load. The hot water generated by electricity has the thermal storage property, which can consume fluctuating wind power. The load group sliding mode control strategy of electric water heater for absorbing wind power is proposed to control the load group of electric water heater in real time. The control rate is related to the number of electric water heaters and the use of hot water,and has strong robustness for absorbing wind power. A simulation on the load group of electric water heater in a residential area shows that the proposed group sliding mode control strategy of electric water heater can effectively absorb the wind power, which verifies the effectiveness of the load group sliding mode control strategy of electric water heater.
