Abstract

In order to solve the pressure caused by large-scale integration of new energy power generation into power grid and improve the flexibility of combined heat and power (CHP) units, it is necessary to compare and select various deep peak regulation technologies. Based on the operation rules of auxiliary services, the benefit model of deep peak regulation of CHP units in heating period was derived. Taking an actual CHP unit in Northeast China as the research object, power regulating abilities and benefits of deep peak regulation of five kinds of technical schemes were calculated and compared. The calculation results quantitatively evaluated the technical economy of each scheme and showed that the combined application of the scheme with good thermal economy and the scheme with strong power regulating abilities has better benefits for the deep peak regulation of CHP units.
