摘要: |
风机、光伏等可再生能源出力和负荷需求的不确定性给微电网稳定运行带来挑战。首先,针对这一特性,构建约束条件的不确定集,综合考虑运行成本和环境成本,建立微电网多目标鲁棒调度模型,并引入鲁棒不确定预算调节不确定集合的保守度。其次,采用基于Pareto支配策略的改进的非线性多目标布谷鸟算法求出Pareto最优解集,并利用多目标灰靶决策从Pareto最优解集中选择出满意方案。最后,针对一个小型微电网系统建立优化模型并求解,对比分析仿真结果,验证了所提方法的可靠性和有效性。 |

Abstract: |
There are uncertainties in load demands and renewable energy outputs of wind turbine and photovoltaic. These factors bring great challenges to the stable operation of microgrids. In view of the characteristic, firstly, the uncertainty set of the constraints is constructed and the operating cost and the environmental cost are considered. Thus, the multi-objective robust scheduling model of the microgrid is built. Also, robust uncertainty budget is introduced to adjust the conservatism of the uncertainty set. Secondly, an improved and nonlinear multi-objective cuckoo search algorithm based on Pareto domination is used to solve the Pareto optimal solution set. Based on multi-objective grey target decision-making, the satisfactory solution is selected from the optimal solution set. Finally, the scheduling model for a small microgrid is established and solved. The simulation results are compared to verify the reliability and validity of the proposed method.
