DESIGN OF HYBRID HEAT AND POWER CO-GENERATION SYSTEM

ABSTRACT
The energy revolution considering renewable power is indispensable and inevitable in the development of modern power industry, yet has been restricted by many practical problems. The instability of renewable energy makes the whole power generation system unable to maintain stable output, which causes fluctuations in the power grid system, and ultimately affects the user side. Also, there are few researches on hybrid heat and power co-generation system and when applied to the regional power supply, current systems converse electric energy to thermal energy to meet the heating demand of users, which reduces the energy quality. Hybrid two or more kinds of renewable energy is a way to eliminate instability of renewable energy power generation system. In this paper, a hybrid heat and power co-generation system is designed to reach both heat and power demands of users, a solar-geothermal power generation system was simulated on ASPEN PLUS platform. The output power, entropy and energy efficiency are analyzed to optimize the system. Based on the solar-geothermal power generation system, exergy analysis shows that the parallel heating and power generating system is much more efficient than the original system.
