摘要:

风光储发电系统的特点是集电网支路接入电源数量多,放射状和链状集电网的分支线路首端发生故障,导致大量电能损失。为了提高风光储发电系统的可靠性,提出采用格式网模式的配电网构建风光储集电系统,在此基础上,建立了考虑电量效益和电缆成本约束的集电网规模优化模型,以及基于遗传算法理论的格式网集电网规模优化算法,研究了格式网模式的风光储集电网的集电规模及电量效益等问题。通过研究和算例分析,证明了格式网模式的集电网汇集的优势,以及优化模型及算法的有效性。

Abstract:

Due to the characteristics of a large number of power connected into branches in power collection grid, the fault at the beginning of branches in wind-photovoltaic-battery power collection grid with radial and chain topologies will cause enormous power losses. To improve the reliability of wind-photovoltaic-battery generation system, the distribution network in meshed grid mode was proposed to construct wind-photovoltaic-battery power collection grid. On this basis, this paper establishes the optimization model of power collection grid scale with considering electricity revenue and cable cost constraint, as well as the optimization algorithm of power collection grid scale in meshed grid mode based on genetic algorithm theory. Then, this paper studies the power collection scale, electricity benefit and other problems of wind-photovoltaic-battery power collection grid in meshed grid mode. Finally, the research and example analysis prove the  collection advantage of power collection grid in meshed grid mode and the effectiveness of the proposed optimization model and algorithm.
