摘要(Abstract):

为选择经济性更优的RIES(区域综合能源系统)风电消纳方案,基于多能互补原理,分别建立计及P2G(电转气)反应余热再利用的RIES电-气多能互补优化模型、含ASHP(空气源热泵)的RIES电-热多能互补优化模型。考虑P2G和ASHP投资维护成本,以系统综合运行成本最小为目标,建立RIES多能互补经济调度模型,综合考虑能量供需平衡约束、各类机组运行约束等,采用优化软件CPLEX对各类模型分别求解。算例结果表明:计及P2G反应余热再利用能够降低P2G配置容量,提高系统运行效益;在满足相同风电消纳率时,含ASHP的电-热多能互补优化模型的经济性与综合能效更具优势。
In order to select a more economical wind power consumption scheme for RIES(regional integrated energy system),the electricity-gas multi-energy complementarity optimization models considering the reuse of waste heat from power to gas(P2G)reaction and the electric-thermal multi energy complementary optimization model of air source heat pump(ASHP)are established based on the principle of multi-energy complementarity. Taking account of the investment and maintenance cost of P2G and ASHP,the RIES multi-energy complementary economic dispatch model is established with the goal of minimizing the overall operating cost of the system. Constraints of energy supply and demand balance and various unit operation constraints are considered. The optimization software CPLEX is used to solve various models. The example calculation results show that the scheme considering the reuse of waste heat from P2G reaction can reduce the configuration capacity of P2G and increase the operation benefit of the system. On condition of the same consumption rate of wind power,the electric-thermal multi-energy complementary optimization model with ASHP is superior in economy and overall energy efficiency.
