基于能量实时协调控制的船舶微电网电源优化配置

摘要

论文以风、光、柴、蓄能源混合的独立船舶微电网为研究对象,对分别作为主控制电源的柴油发电机组和蓄电池储能系统提出了两种不同的运行控制模式,并相应设计了两种能量管理调度策略.针对系统的电源优化配置问题,构建了计及系统全寿命周期的设备成本、微电网容量缺失及污染物治理成本为目标函数的三目标优化设计模型.该模型采用非支配性排序遗传算法(NSGA-Ⅱ)进行求解,对不同电源组合、不同能量控制策略对独立微电网多目标配置优化结果的影响进行研究分析.通过在同一电源配置下采用不同策略和不同蓄电池荷电状态(SOC)上限,对各电源输出功率情况影响的仿真结果分析,验证了优化模型的实用性和科学性.%Based on wind-solar-diesel-battery hybrid energy,an independent marine micro-grid was studied in this paper.Two operation modes were put forward for battery energy storage system and diesel generators,used as the main power supply,respectively.Correspondingly,two strategies of energy management dispatch were designed.A three-objective optimization model was constructed,with the whole life cycle of the equipment cost,the micro-grid capacity loss and the cost of pollutant government as objective functions.The model is solved with the non-dominated sorting genetic algorithm (NSGA-Ⅱ).Influence of the output power on various power supplies is analyzed,and practicability of the optimization model is verified.
