摘要
潮流能是海洋能的重要组成部分,针对孤岛微网分布式电源容量配置问题,提出了含潮流能/风/蓄/柴的孤岛微网容量优化配置模型。该模型综合考虑了初始投资费用、运行与维护费用、更换费用以及燃料成本,并采用粒子群优化算法对模型进行求解。分析比较了潮流能/风/蓄、风/蓄/柴、潮流能/蓄/柴和潮流能/风/蓄/柴四种容量配置方案,结果表明所提方案能有效降低微网总成本。此外,还对供电可靠率对孤岛微网年投资运行总成本的影响进行了灵敏度分析。
Tidal energy is an important part of ocean energy.To solve the capacity configuration of distributed generation in insular island,an optimal allocation model of micro-grid with tidal/wind/battery/diesel in insular Islands micro-grid was put forward in this paper.The model takes account of initial investment cost,operation and maintenance cost,replacement cost and fuel cost,and applies particle swarm optimization algorithm to solve the model.Four configuration schemes are compared and analyzed.The results show that the proposed scheme can effectively reduce the total cost of micro-grid.In addition,sensitivity analysis is used to investigate the effects of power supply reliability on optimization results.
