Techno-economic analysis of a hybrid energy system for CCHP and hydrogen production based on solar energy

A typical problem in Northeast China is that a large amount of surplus electricity has arisen owing to the serious photovoltaic power curtailment phenomenon. To effectively utilize excess power, hybrid energy system proposed uses produce hydrogen this paper. It combines solar energy, production system, and Combined Cooling Heating Power (CCHP) realize cooling, heating, generation. The supplies for three public buildings Dalian City, Liaoning Province, China, configuration with lowest unit cost (0.0615$/kWh) was obtained via optimization. Two comparison strategies were used evaluate terms cost, annual total fossil consumption, carbon dioxide emissions. Subsequently, supply, daily loads, optimized analyzed. In conclusion, feasible small area buildings, provides solution solve phenomenon curtailment.
