摘要
当电网中大量接入风电供暖系统时,若对含储热的电供暖系统采用完整模型进行调度计算,会导致计算量显著增加。为此考虑风电供暖系统的实际情况对其进行简化,提出了储热式电供暖简化线性调度模型,决策变量只包含风电供暖系统的用电功率,模型只有线性的等式约束和不等式约束。仿真分析表明,采用简化线性调度模型可以满足电网调度运行要求,大大减少了含储热风电供暖系统加入电网调度系统时增加的计算量。
There will be a significant increase in calculation if we use a complete model for dispatching planning when the power system is integrated with a large scale of wind heating systems with thermal storage.For this situation,we suggest a linear dispatching model for wind heating system with thermal storage based on the operation condition of the real wind heating system.The simulation results show that the use of a linear dispatching model can also meet the requirements of daily operation.Its impact on the existing dispatching system is small.
