摘要:

研究了海岛风-光-海水抽蓄联合发电系统的调度策略问题。提出了联合发电系统的3种调度方法，包括“单一型调度”、“一次复合型调度”和“二次复合型调度”。根据每种调度方法，设计多种相应策略，包括3种“单一型调度”策略、3种“一次复合型调度”策略和6种“二次复合型调度”策略。以南麂岛为例，先对12种调度策略下的联合系统分别进行基于模糊多目标规划与遗传算法的容量优化，然后分析比较12种调度策略下的系统最佳容量配置的运行结果，总结3种调度方法的利弊，并选取最佳调度策略。

Abstract:

This paper researches the dispatching problem of a wind-solar-seawater pumped storage hybrid power system in sea islands, puts forward three kinds of dispatching methods of the hybrid power system, which include single dispatching, simple mixed dispatching and complex mixed dispatching. On basis of each kind of dispatching method, several kinds of related dispatching strategies are designed, including three kinds of single dispatching strategies, three kinds of simple mixed dispatching strategies and six kinds of complex mixed dispatching strategies. Taking Nanji Island for an example, first, this paper optimizes the capacity of the hybrid system of 12 dispatching strategies based on fuzzy multi-objective programming and genetic algorithm, then analyzes and compares operation results of optimal capacity allocation of 12 dispatching strategies, summarizes the advantages and disadvantages of the three dispatching methods and selects the best dispatching strategies. This work is supported by National High-tech R & D Program of China (863 Program) (No. 2014AA052003).
