摘　　要：常规的新型风电场相变储能功率分配,主要采用自适应的控制规律来实现储能功率的分配,忽略了风电场的剩余功率对分配结果的影响,导致分配结果功率波动量较大。因此,提出基于模糊支持向量机的新型风电场相变储能功率分配研究,对新型风电场相变储能功率调节范围进行设定,通过概率分布曲线确定剩余功率最大值,计算分配节点能量熵,将其代入到建立的模糊支持向量机模型中,对功率分配能量熵进行优化,代入节点电路完成相变储能功率的分配。实验结果表明:所提方法应用后得出的功率分配结果,表现出的功率波动量较小,均值为1.55 MW,分配结果显著,满足了新型风电场的运行需求。Conventional power distribution of phase change energy storage in new wind farms mainly adopts adaptive control laws to achieve the distribution of energy storage power,ignoring the impact of the wind farm's excess power on the distribution results,leading to large fluctuations in the distribution results.Therefore,a new type of wind farm phase change energy storage power distribution based on fuzzy support vector machine is proposed.The power adjustment range of the new wind farm phase change energy storage is set,the maximum value of the remaining power is determined through the probability distribution curve,the energy entropy of the distribution node is calculated,and it is substituted into the established fuzzy support vector machine model to optimize the power distribution energy entropy.The node circuit is substituted to complete the distribution of phase change energy storage power.The experimental results show that the power distribution results obtained after the application of the proposed method show small power fluctuation,with an average value of 1.55 MW,and the distribution results are remarkable,which meets the requirements for the operation of new wind farms.
