Abstract: Biomass power generation is one of the important renewable energy power generation technologies,which has become a stable low-carbon power source technology.With the implementation of the strategic goal of“carbon peak and carbon neutrality”,biomass power generation faces new challenges and opportunities.The biomass power generation technology and the engineering system evolution trend of TRIZ theory are briefly introduced. Combined with the S curve and evolution trend followed by the development of engineering system,the development stage of the biomass power generation engineering system in the S curve,the corresponding main value parameters,market,function and technical characteristics of the engineering system are analyzed,and proposed strategies to improve the value trend.Combined with the engineering system evolution trend of the modern theory of TRIZ,a detailed analysis of biomass power generation engineering system towards super system,system completeness,increasing cropping,flow enhancement,system coordination,controllability,dynamic non-uniformity,reducing artificial intervention,subsystem of evolution trend,and enumerate the emerging and possible technological forms. A case for TRIZ to predict the development trend of energy technology,and reference for the technology and equipment research,and unit operation management of biomass power generation engineering system is provided.
