Abstract

Abstract: In light of the increasing imbalance between the electric and heat loads during the heating period in the Sanbei area, it is critical that the thermal power units can participate in deep peak load regulation and realize the thermoelectric decoupling during that period of time. The technical schemes for improving the flexibility of the thermal power units are analyzed and studied in details from different aspects, such as, the technology roadmap, the scope of applications, etc. The hot water thermal energy storage system and electric boiler system are devised according to the specific project conditions. The analysis indicated that the hot water storage system, the electric boiler system, and the temperature and pressure reduced heat supplying system can all enhance the operational flexibility of the thermal power units and increase the peak load regulation depth of the unit. The different schemes also have their own scopes of application.

Key words: thermal power unit, flexibility of operation, in-depth peak load regulation, thermal energy storage, electric boiler
