| description | China has actively carried out the pilot work for flexibility transformation of thermal power. Multiple types of heat sources have played an important role in accommodation of wind power, and reasonable heat source capacity planning can effectively improve wind power accommodation. With consideration of the heat storage characteristics that the thermal system naturally has in heat power capacity planning, the joint optimization of power system and thermal system can be realized, and the economic cost of heat source allocation can be further reduced. Firstly, a thermal characteristic model is established for each part of the thermal system, including heat source, heat supply network, and heat load; And then, a time-series production simulation model is constructed for optimal capacity planning of multiple heat sources, with the goal of minimizing the annual economic cost of the heat source; Finally, based on the constructed model, the heat source allocation schemes and their economic comparison are studied under different scenarios, which can provide a reference for heat source planning. |
