基于含储热热电联产机组与电锅炉的弃风消纳协调调度模型

Coordinated Wind Power Accommodating Dispatch Model Based on Electric Boiler and CHP With Thermal Energy Storage

为解决风电消纳问题,从解耦热电耦合约束、提升电力系统调节能力角度出发,提出基于含储热热电联产机组与电锅炉的弃风消纳协调调度模型。在分析含储热热电联产机组工作原理基础上,提出极限消纳弃风电量的电锅炉供热量计算方法,对比了储热装置不同工作方式以及含储热热电联产与电锅炉协调供热时的经济性。算例结果表明,电锅炉供热在极限消纳弃风时具有最佳经济性。

To solve the problem of wind power accommodation, this paper proposed a coordinated wind power accommodating dispatch model based on electrical boiler （EB） and cogeneration units with thermal energy storage （TES）, with the perspective of decoupling thermoelectric coupling constraints and enhancing the adjustment capacity of the power system. This paper analyzed the principle of cogeneration units with TES, and presented the calculation method of the ultimate wind power accommodated heating capacity of the EB. Then the economy had been compared considering the TES work alone or does not work, as well as the two heating units work coordinately. Example results show that the best economy could be achieved when the EB heating capacity reached the ultimate wind power accommodated heating capacity.
