提出一种含多风电场的电力系统储能鲁棒优化配置模型，最优解为满足风电功率全部接纳要求的储能装置最小功率容量和最优布点方案。模型考虑系统网架结构的输电能力限制，并引入功率平衡线性分配策略优化分配系统内可调机组和储能装置应对风电功率波动的能力，以充分利用常规机组的调节能力。采用风电功率均值和波动区间上下限描述风电功率的随机性，应用鲁棒线性优化方法将不确定性模型转化为确定性模型进行求解，避免了建模和求解过程中对随机变量概率分布函数的依赖性。仿真分析结果验证了所提出模型和算法的有效性。

ABSTRACT:The capacity limits of transmission network and flexible units were considered as bottlenecks to accommodate wind power in power system. To solve the problem of insufficient flexibility, this paper proposed a novel optimization model to obtain the minimum power capacity and appropriate distribution of energy storage. A linear relationship was introduced to demonstrate the accommodative distribution for wind power variation and then to maximally utilize flexible units and minimize the requirement of energy storage. The mean value and interval bound were used to describe wind power variation uncertainty and the conversion into certainty was realized according to the robust linear optimization. Thus, the feasible solution which is immunized against uncertainty is solved without depending on the probability distribution of wind power. The simulation results show the effectiveness of the proposed model.
