Standard system construction for flexible coal-fired power generation
Enhancing the flexibility of coal-fired power generation is a crucial for promoting clean energy consumption,green-oriented transition of energy and energy security guarantee.The construction of a comprehensive standard system for the flexible coal-fired pow-er generation is a key step for promoting flexible coal-fired power generation development.Based on the essence of flexible coal-fired pow-er generation,the current reconstruction and construction of flexible coal-fired power generation face four main challenges were proposed,such as difficulties in breaking through on flexibility indicators,prominent safety issues under flexibility,a significant decline in economic indicators under flexibility,and difficulties in ensuring cleanliness under flexibility.In response to four key challenges,a preliminary frame-work for a comprehensive coal-fired power plant flexibility standard system has been established,taking into account goals,specialized cat-egories,and functional sequences.This framework covers processes including general use,design,manufacturing,installation,testing,meas-urement,operation,and evaluation.Based on the current state of flexibility development in coal-fired power generation and related standards,it is proposed to focus on several key areas for standard development:terminology and evaluation of flexibility standards,safe oper-ation and life assessment of flexible units,efficiency evaluation under flexible operation of coal-fired units,carbon dioxide detection and pol-lutant emission control,and online monitoring of coal-fired power generation units.The efficiency evaluation methods will particularly address non-steady-state and deep load-following abnormal conditions,with special emphasis on online monitoring technologies for fuel quality and coal flow,as well as the establishment of flexible control standards for fuel-burning-working fluid interactions.The proposed framework and suggestions can be served as revision and establishment references for the standards related to flexibility of coal-fired power generation.
