Abstract

Due to the urgent need for a method that can objectively reflect the energy efficiency evaluation of novel power systems

based on the viewpoint of systems engineering and a thermo-economic state equation for modern power systems

the steam-water distribution state equation of the system and general equations for transfer and analysis of output work and cycle heat absorption were constructed

corresponding one-to-one with the structure of the power plant's thermal system. Based on this

carbon capture

energy storage

wind power

photovoltaics

and solar thermal power were treated as auxiliary systems to explore their integration mechanisms with the thermal system of the thermal power units. A novel wind-solar-fire-storage complementary hybrid power generation system considering carbon capture system was proposed

and a general equation for energy efficiency evaluation and calculation of the multi-energy complementary hybrid power generation system was established. Finally

the proposed method was verified through a case study. Results show that the method possesses the characteristics of being universal

precise

and programmable

which makes the overall calculation and local analysis of the complex system energy efficiency clearer

providing theoretical support for the energy efficiency evaluation of clean and low-carbon novel power systems.
