摘　　要：由于远洋海岛无法获得大陆主电网的支持,且其常规机组的燃料补给线超长,传统发电配置方法并不能直接适用于对远洋海岛可再生能源发电机组进行配置和方案优选。对此类远洋海岛而言,储量丰富的可再生能源应作为建设绿色海岛能源供应系统的主要依托。该文基于全清洁化远洋海岛能量供给系统的拓扑特性与基本框架,并计及远洋海岛自然环境和功能定位,分别建立契合海岛可再生能源出力及负荷短时间尺度波动规律的概率模型。在此基础上提出的基于归一化积相关算法（normalized product correlation,NPROD）能有效支撑长时间尺度基础负荷、并能实现海岛能量供给系统出力/电量—负荷最佳匹配的可再生能源机组配置方案优选策略。最后,通过算例仿真验证所提配置方案优选策略的合理性和优越性。As the pelagic islands cannot rely on the support from the main power grid, together with the extreme long fuel replenishment line, the traditional energy generation configuration methods cannot be directly applied for configuring the renewable energy generation units of pelagic islands. Instead, the abundant renewable energy should be the major support of pelagic island power supply system. To solve this problem, the appropriate probabilistic models of renewable energy generation and island electrical loads were established in this paper. On the basis of above, a normalized product correlation （NPROD） based scheme optimally- selecting strategy was proposed, which can effectively support the base load and realize the perfect matching between the generation and the load demand of pelagic island energy supply system. Finally, the rationality and superiority of the proposed strategy was verified through extensive case studies.
