摘要：
A new parabolic trough solar thermal and photovoltaic combined cooling heating and power (PV/PTST-CCHP) system is established in this paper. Ordering power by heat (OPH) strategy and ordering heat by power (OHP) strategy are studied and the capacity configuration of the system is optimized. The research object is a cogeneration system of cold, heat and electricity, which is dominated by trough solar thermal power and supplemented by photovoltaic and gas turbine power generation. Taking a hotel in Beijing as an example, mathematical models are established for the purpose of economic, energy and environment based on whole life-cycle. The operation strategy with advantages is selected through the comparison of various indicators. The hill climbing algorithm (HCA) is used to optimize the configuration of the system under the optimal operation strategy and indexes under the optimal configuration are compared with those of the sub-supply system. The results show that the PV/PTST-CCHP system has more advantages than the sub-supply system. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
