计及弃风的多锅炉耦合协调供暖优化及经济性分析

OPTIMIZATION AND ECONOMIC ANALYSIS OF MULTI-BOILER COUPLED COOROINATION HEATING CONSIDERING ABANDON WIND POWER

传统供暖方式受到"以热定电"的约束。针对供暖地区大气污染和弃风现象严重的问题,为解耦热电耦合约束并促进弃风的进一步消纳,该文提出利用电锅炉对燃煤或燃气锅炉进行辅助供暖的多锅炉耦合协调供暖方式。考虑到供暖成本,根据不同电锅炉容量的弃风消纳能力构建电-燃煤锅炉和电-燃气锅炉耦合协调供暖经济性模型,对电锅炉容量进行优化配置。最后对4种供暖方式进行经济性分析。算例分析结果表明:多锅炉耦合协调供暖和其他供暖方式相比能减少20%的碳排放,同时其收益率要高于单一类型锅炉的供暖方式,具有较高的经济性,为弃风消纳提供了一条新的途径。

The traditional heating mode is constrained by“determining electricity by heat”. Aiming at the serious problems of air pollution and wind abandonment in heating areas, a multi-boiler coupled coordination heating method using electric boilers as the auxiliary heating of coal or gas boilers is proposed in order to decouple the thermoelectric coupling constraints and promote the dissipation of abandoned wind. Considering the heating cost, an economic model for the coordination heating of electric-coal-fired boilers and electric-gas-fired boilers was constructed based on the receiving ability of the abandoned wind of different electric boiler capacities.At the same time, the capacity of electric boilers was optimized. Finally,the economics of the four heating methods were analyzed. The analysis of the example shows that compared with other heating methods,multi-boiler coupling coordination heating can reduce carbon emissions by 20%,and its yield is higher than that of single-type boilers. It has high economic efficiency and provides a new way to consume the wind power.
