长期并网运行的海岛微电网电源容量优化配置
摘要:针对并网运行的海岛微电网中分布式电源容量优化配置问题，建立分布式能源(风、光、柴、储)的数学模型，同时对连接海岛微电网与陆上电网的海底电缆进行可靠性建模，考虑不同情况对海底电缆模型参数的影响。在分布式能源模型和海岛电缆模型的基础上，建立计及设备初始投资成本、运维费用、替换成本、输电费用和余量上网费用等因素的目标函数。在供电可靠性、功率平衡等约束条件下，通过遗传算法求解，得到最优的容量配置。最后与升级海底电缆比较，进行定量分析，考量海岛微电网的合理性与经济性。
Abstract：Aimming at the optimal configuration of distributed power capacity in the grid-connected island microgrid, the mathematical model of distributed energy (wind, light, wood, storage) is established; at the same time, the reliability modeling of submarine cable connecting island microgrid and land power grid is carried out, and the influence of different conditions on the parameters of submarine cable model is considered. On the basis of distributed energy model and island cable model, the objective function is established to take into account the initial investment cost, operation and maintenance cost, replacement cost, transmission cost and spare online cost. Under the constraints of power supply reliability and power balance, the optimal capacity configuration is obtained by genetic algorithm. Finally, the rationality and economy of island microgrid are considered by quantitative analysis compared with the upgrading of submarine cable.
