摘要
北方地区为了实现清洁供暖、降低弃风率,投入各种电制热储热装置,尤以热电厂为了提高调节灵活性而投入的大容量电制热储热装置最为有效。提出了热电厂投入的大容量电制热储热装置消纳的电量计算方法和电网弃风电量计算方法,研究了电制热储热装置投入时序和弃风发生时序的关系,探讨了电制热储热装置投入后机组深度调峰的延时性。实际运行数据分析表明,弃风发生时序与电制热储热投入时序对于北方地区通过大容量电制热储热消纳弃风起到示范作用。
In order to achieve clean heating and reduce the rate of abandoned wind,the northern region has invested in various heat storage devices,especially the large-capacity heat storage devices invested by thermal power plants to improve adjustment flexibility.The power consumption calculation method of large-capacity heat storage device invested by thermal power plants and the calculation method of abandoned wind power in power grid were proposed.Moreover,the relationship between the input timing of the heat storage device and the timing of abandoning wind was researched,and the delay of deep peak shaving of the unit after the input of the heat storage device was discussed.The actual data show that the input timing of the heat storage device and the timing of abandoning wind have a demonstration effect on the consumption of wind power through thermal storage in the northern region.
