摘要
提出了双层协调调度的方法——计划调度层和实时调度层来解决微电网孤网实时能量优化管理的问题。计划层是基于不可控微电源功率预测的主要考虑微电网经济性的调度方法;实时层是在计划层的基础上对不可控微电源实际功率与预测功率之间的误差进行调度,再将调度结果叠加到计划层各个可控微电源的功率上。在实时层,可控微电源的功率范围与计划层是不同的,下限为其在计划层出力的相反数,上限为其最大出力与计划层出力差值。最后通过一个典型的微电网实例验证了该方法的正确性和优越性。
This paper puts forward the method of double-layer coordinated scheduling, which are planning scheduling layer and real-time scheduling layer, to solve the real-time energy optimization management problem in the stand-alone mode. Planning layer mainly considers ecnomic of microgrid based on uncontrolled micropowers power predicting while real-time layer dispachs the errors between actual power and forecasting power of uncontrolled micropowers on the basis of the planning layer , and adds the dispaching result to the planning layer. In real-time layer, controllable power′s range of micropower supply is different with the planning layer, the lower limit is opposite of output of micropower in the planning layer, the upper limit is the difference value between maximun power to output of micropower in the planning layer. Finally, a typical microgrid is used to verify the correctness and superiority of the proposed method.
