| Summary: | The existing optimization scheduling of regional CCHP system does not take into account the different control objectives and response characteristics of each unit under multiple operating states in the whole operation domain, so it is difficult to achieve the unified traction control of multiple operation stages of multiple units. To this end, this paper proposes a unified traction control strategy for multi-state operation of regional CCHP system. Based on the different control objectives and response characteristics CCHP unit under multiple states, a two-layer traction control strategy of the regional CCHP system and unit was established. The upper level takes into account the different control objectives and response characteristics of each unit under different operating states, and optimizes the target operating state of each traction unit. The lower level realizes the efficient traction control of each unit under the target operating state based on the optimization decision results. Finally, a simulation example is designed to verify that this paper can effectively consider the different control objectives and response characteristics of CCHP unit under different operating states to achieve the optimal traction control.
