摘　　要：本文采用多目标遗传算法和逼近理想解排序法(TOPSIS),研究了包含光伏、光热、内燃机、吸收式机组、地源热泵、燃气锅炉、蓄电池和蓄水罐在内的太阳能-地热能-天然气互补的楼宇型供能系统在不同时间尺度运行策略下的系统运行情况,并结合市政电网的峰谷价格特性建立了多能互补供能系统优化模型,分析了系统在不同策略的经济、能源和环境性能变化。结果表明:经济、能源和环境指标不能同时达到最优值;与季变化策略相比,月变化策略的经济、能源和环境性能分别提升2.26%、7.61%和7.41%,而日变化策略的经济、能源和环境性能则分别提升了3.02%、24.29%和23.15%;最佳的运行策略是日跟随策略和市政电价相结合的策略,所对应的经济、能源和环境性能指标分别为149万元、388 372 kW·h和91 t。Multi-objective genetic algorithm and technique for order preference by similarity to ideal solution(TOPSIS)method are used to study the system operation of solar energy-geothermal energy-natural gas complementary building energy supply system including photovoltaic,solar thermal,internal combustion engines,absorption units,ground source heat pumps,gas boilers,batteries,and water storage tanks under different time scale operation strategies.A multi-energy complementary energy supply system optimization model is established based on the peak and valley price characteristics of the municipal power grid and the changes in economic,energy and environmental performance of the system under different strategies is analyzed.The results show that economic,energy and environmental indicators cannot reach optimal values at the same time.Compared with the seasonal change strategy,the economic,energy and environmental performance of the monthly change strategy are improved by 2.26%,7.61%and 7.41%,while the performance of the daily change strategy is improved by 3.02%,24.29%and 23.15%,respectively.The best operation strategy is a combination of daily following strategy and municipal electricity price,and the corresponding economic,energy and environmental performance indicators are 1.49 million yuan,388372 kWꞏh and 91 t.
