Primary Frequency Regulation Strategy for Operating Thermal Generator Units Facilitating Deep Peak Shaving
The present work made an attempt to establish the primary frequency regulation strategy of operating thermal generator units considering the demand of deep peak shaving,with the aim of optimizing primary frequency regulation util-ity and achieving standardized operation of thermal generator units.First the frequency characteristic of thermal generator unit was modeled to evaluate the unit performance.Second the objective of deep peak shaving was determined considering the unit's operating condition and characteristics,and the grid's demand.Then the parameters and control algorithm of primary frequency regulation were calculated and designed according to the frequency variation requirements and response capabilities of the unit,thereby achieving algorithm-driven actions of the executing mechanism and the frequency modula-tion control objective.The proposed strategy was indicated by experiment to achieve standard-qualified primary regulation performance for the unit subjected to load adjustment disturbance of 40％Pe or 30％Pe,and thereby to have the potential of standardized control.
