摘要
针对混合能源微电网动态调度优化问题,提出基于多模式调度策略和调度激励相结合的策略驱动优化调度方法,以实现储能单元与外部电网功率互补,优化电源出力。首先,综合考虑混合能源微电网基本结构,建立微电网模型,基于爬坡功率、发电单元出力、能量守恒等约束条件,提出运行成本和环境整治成本最小的目标函数;其次,在成功经验和专家知识的基础上,结合调度激励机制提出微电网调度策略驱动模型;最后,通过Matlab仿真及算法对比表明,该优化算法具有收敛速度快、局部与全局的搜索能力强等特点。
Aiming at the dynamic dispatching optimization of hybrid energy microgrids,a strategy-driven optimal dispatching method based on the combination of multi-mode dispatching strategy and dispatching incentive is proposed.The power complementation between the energy storage unit and the external power grid is realized,and the power output is optimized.Firstly,considering the basic structure of hybrid energy microgrids,a microgrid model is established.The objective function of minimizing operation cost and environmental remediation cost is proposed based on the constraints of climbing power,power unit output and energy conservation.Secondly,the dispatching strategy-driven model of microgrids is proposed based on the successful experience and expert knowledge,combined with dispatching incentive mechanism.Finally,MATLAB simulation and algorithm comparison show that the proposed algorithm has the characteristics of fast convergence,strong local and global search ability.
