【摘要】：含分布式冷热电联供(combined cooling,heating,and power,CCHP)型的微电网技术,是提高微电网内能源利用效率、满足供需就地平衡的有效手段。提出1种冷热电联供型微电网经济调度方法,以实时电价及负荷需求作为参考,通过模糊理论确定微网向外购售电及网内各微源输出功率;考虑到热(冷)负荷及间歇性电源的随机扰动性,采用模型预测控制(model predictive control,MPC)对其加以控制;为保证闭环控制的稳定性,对储能SOC进行模糊自适应控制,将控制的输出作为滞后的反馈矫正环节对控制偏差进行修正,以保证闭环控制的稳定性。以国内某一试点工程作为算例,验证了该方法的正确性和有效性。
[Abstract]:The microgrid technology with distributed combined cooling and cooling and power CCHPs is an effective means to improve the energy utilization efficiency and meet the local balance of supply and demand in microgrid.In this paper, a new economic dispatching method of combined cooling and heat power supply microgrid is proposed. Based on the reference of real time electricity price and load demand, the output power of micro source is determined by fuzzy theory.Considering the heat (cooling) load and the random disturbance of intermittent power supply, the model predictive control model predictive control (MPCs) is used to control it, and to ensure the stability of closed loop control, the fuzzy adaptive control of energy storage SOC is carried out.The output of the control is used as the feedback correction link to correct the control deviation to ensure the stability of the closed-loop control.The correctness and validity of the method are verified by a pilot project in China.
