为提高能源系统综合性能,将地源热泵、光伏和光热等可再生能源集成于以原动机为核心的冷热电系统,并着重对系统设备的效率进行研究。基于设备能量互补特性,提出优化多个设备运行参数,分别是地源热泵供冷启动因子和供热启动因子以及原动机的启动因子来实现整个系统设备效率的提高。将控制多个设备的启动因子结合以电定热运行模式与传统以电定热运行模式进行对比分析,并以单独的地源热泵系统为参考系统,采用黑洞算法对系统进行优化。研究结果表明,与传统模式相比,控制多个启动因子模式系统具有更好的性能。与参考系统相比,耦合可再生能源的冷热电系统性能指标有了较大改善,特别是以启动因子模式运行（年能源节约率达到36.03%;年CO2减排率达到53.24%;年总成本降低率达到36.85%;年综合性能达到42.04%）。
Abstract
In order to improve the overall performance, the combined cooling, heating and power system is analyzed with power generation unit as the core. The system combines renewable energy which include ground source heat pumps, photovoltaics and solar thermal technologies. The efficiency of the system is focused on research. Based on device complementary characteristics, the way is proposed by optimizing a number of control parameters. The parameters include the start factors of the ground source heat pump in cooling and heating mode and the power generation unit. Combining the start factors of controlling multiple devices with following electric load operation mode and the following electric load operation mode are comparative analysis. The black hole algorithm is used to optimize the system. The research results show that the system has better performance with multiple start factors compared with the traditional model. Compared with the reference system, the performance indicators of the renewable energy system have been greatly improved, especially using the start factor mode operation （the annual energy saving rate reaches 36.03%; the annual carbon dioxide emission reduction rate reached 53.24%; the total annual cost reduction rate reached 36.85%; the annual comprehensive performance reached 42.04%）.
