摘要
为解耦热电厂中热电机组"以热定电"的刚性约束,提高风电消纳能力,降低碳排放成本,研究启停电锅炉与储热装置协调供热策略,建立基于启停电锅炉与储热装置协调供热的风电消纳低碳经济调度模型。该模型以经济环境成本最低为目标,引入碳排放成本参数,考虑热电机组热电耦合约束,热、电平衡以及机组爬坡等约束。算例对4种供热方式下系统的风电消纳水平,煤耗成本以及碳排放成本进行分析。算例结果验证所提模型有效性与准确性。
In order to decouple thermoelectric coupling constraints of cogeneration units in cogeneration plants,improve the capacity of wind power consumption,and reduce the carbon emission cost,the coordinated heating supply strategy of start-stop electric boiler and heat accumulator is studied in this paper.Wind power accommodation low-carbon economic dispatch based on coordination between automatic start-stop electric boiler and heat accumulator heating supply model is established.This model aims at minimizing the economic and environmental cost,introducing carbon emission cost parameter and considering the thermoelectric coupling of cogeneration units,the heat and electric power balance,the units ramp rate,etc.The wind power accommodation,the cost of coal consumption and carbon emission cost in four different ways of heating supply are analyzed.The effectiveness and validity of the proposed model are verified by the results of the numerical examples.
