基于蓄热罐运行平面的电热耦合系统调度策略

SCHEDULING STRATEGY OF ELECTRO-THERMAL COUPLING SYSTEM BASED ON OPERATING PLANE OF HEAT STORAGE TANKS

热电联产机组在配置蓄热罐后可增加电网消纳新能源的能力,但由于蓄热罐的接入也同时增加了电网调度的难度。提出一种基于蓄热罐运行平面的电热耦合系统调度策略,该策略可对蓄热罐进行实时控制,从而进一步增加风电的消纳量。在考虑风电不确定性的基础上,采用一种简化的方法确定最佳蓄热罐运行平面。该文采用不同情景下的算例验证平面的一般性和准确性。结果表明,与传统的调度策略相对比,此控制策略在实时调度中可进一步增加风电的消纳量。

After the heat accumulators being equipped in the combined heat and power units,the peak load regulation capacity is greatly increased,which can increase the amount of consuming wind power. This paper proposes a strategy for the complementary of electro-thermal coupling system based on the operating plane of heat accumulators. The strategy can control the heat accumulators in real time,thereby further increasing the consumption of wind power. On the basis of considering the uncertainty of wind power,the optimal heat accumulator operation plane is established. The generality and accuracy of the plane are verified using examples under different scenarios in this paper. The results show that the control strategy proposed in this paper can further increase the consumption of wind power in real-time scheduling compared with the traditional scheduling strategy.
