摘　　要：目前的研究中,微电网中负荷与储能、分布式电源运行控制之间的结合不够紧密,缺乏储荷间的一体化控制方法,以减小微电网对储能系统的依赖,降低对混合储能系统配置的容量需求。提出了一种可控负荷与混合储能的集成控制方法,设计负荷储能混合控制系统(HLSS),详细介绍了HLSS的结构,控制流程,就HLSS内部功率最优分配策略进行重点叙述,综合考虑微电网功率平衡、用户体验与经济运行,建立采用基于对偶单纯型的两段式迭代算法求解的多目标优化模型。仿真表明,CL可以解决HESS大容量应用时的高成本问题,而HESS的精确调节性能可以补偿CL的非线性功率特性。In this paper, a flexible control strategy based on the integration of the controllable loads （CL） and hybrid energy storage system （HESS） in microgrid is presented, which introduces the structure and the control flow of the designed hybrid load and storage system （HLSS）. The internal power optimal allocation model is emphatically described based on the analysis of the characteristic of HESS and CL. Considering the power balance, user experience and economic operation of the microgrid, the multi-objective optimization model which is solved by the two-phase iterative algorithm based on dual simplex method is established. The simulation results show that CL can solve the high cost problem of large capacity storage of HESS, and the precise regulation performance of HESS can compensate the nonlinear power characteristics of CL.
