摘　　要：引入太阳能分担热电联供机组热负荷,是提升机组调峰能力及可再生能源消纳的有效措施。本文基于线性规划方法,以太阳能辅助热电联供机组运行收益最大为目标,建立了包含太阳能集热场、储热系统和热电联供机组在内的太阳能辅助热电联供机组运行优化模型,并采用GAMS软件和CPLEX求解器进行求解。以河北某330 MW热电联供机组为例,根据典型日和供热季逐时气象数据和负荷条件进行算例分析,得到太阳能辅助热电联供机组总运行收益和关键设备的逐时出力分配。结果表明:优化后的太阳能辅助热电联供机组能够满足用户负荷需求,且相较于独立燃煤热电联供机组在可再生能源消纳、节煤和经济性方面优势明显。Introducing solar energy to share heating load with combined heat and power(CHP)unit is an effective way to improve the peak-shaving ability of the unit,and to increase the accommodation of renewable energy.Based on the linear programming method and with the goal of maximizing the operation income of the solar-aided CHP unit,an operation optimization model for the solar-aided CHP unit,which contains solar field,thermal energy storage system and CHP unit,has been built.The model is then solved by GAMS software and CPLEX solver.Moreover,a 330 MW CHP unit has been studied as a study case.According to hourly meteorological and load data of the typical day and the heating season,the daily operation income of the solar-aided CHP unit and the hourly output distribution of the key equipment are obtained.The results show that,the optimized solar-aided CHP unit could meet the load demand of customers.Furthermore,the optimized solar-aided CHP unit has significant advantages in renewable energy consumption,coal saving and economy compared with the independent coal-fired CHP unit.
