Abstract

In order to sufficiently explore the operational flexibility of combined heat and power (CHP) units as well as promote the utilization of renewable energy such as wind power and photovoltaics

the effects of the dynamic characteristics of the heating network on the heat system were considered from the perspective of the integrated energy system to dynamically model the heat system for fully exploring its energy storage potential. The operation strategies of the system under different scenarios were analyzed. Furthermore

the effects of the heating network energy storage and the actual energy storage systems on flexibility were compared

and engineering verification was carried out on the actual units. Results show that after considering the dynamic characteristics

the heating network plays the role of thermal energy storage system

leading to the enhancement of flexibility of combined heat and power units and a 4.7% improvement of renewable consumption rate in the set scenario. The analysis of the heating season data shows that the flexibility and the thermal economy of the units are improved

with an increase of 1.7% in the unit efficiency.
