With the ever-penetrating idea of energy saving and emission reduction
the use of solar energy and other forms of renewable energy has become an effective channel to solve the serious fossil energy crisis and environmental pollution. The combined cooling heating and power (CCHP) system is the development trend of the distributed energy system in the future owing to its advantages of high efficiency
less pollution and capability of realizing cascade utilization of energy. By combining solar energy with CCHP system
a system is designed which is able to realize comprehensive utilization of photovoltaic/thermal solar energy while meeting the system need of cooling
heating and electricity load. The indices of energy
environment and economic evaluation are established
and formed as a comprehensive evaluation index using the judgment matrix method. At the same time two kinds of operation modes: ordering power by heating and ordering heating by power are set. And three different control strategies are designed. With a case in point as an example
the optimal refrigerating capacity ratio of electric refrigerator
the optimal capacity of solar generator and the evaluation of operation control strategy are analyzed. Simulation results have verified the correctness and validity of the proposed model and control strategies
providing reference for integrated application of solar energy in the CCHP system. This work is supported by National High Technology Research and Development Program of China (863 Program) (No. 2011AA05A107) and National Natural Science Foundation of China (No. 51177036).
