摘要
以大规模多风电场接入电力系统的一次调频备用容量为研究对象,首先通过引入风电出力预测误差的概率分布描述系统的不确定性因素,考虑风储一次调频备用总成本最小为目标;然后建立基于机会约束规划的多风电场联合共享储能参与一次调频的容量优化模型;最后提出基于快速傅里叶变换快速求解联合变量概率分布的改进p-有效点法通过数学解析将机会约束规划从形式上转化为确定性规划,再通过Yalmip调用Cplex实现模型的快速求解.算例结果表明,所提模型和方法可有效提高风储调频效果和收益,且具有更高的求解效率.
Abstract
The primary frequency regulation reserve capacity of large-scale multi-wind farms connected to the power system is taken as the research object.Firstly,the uncertainty factors of the system are described by introducing the probability distribution of wind power output prediction error,and the minimum total cost of primary frequency regulation reserve of wind power and energy storage is considered as the goal.Then,a capacity optimization model of multi-wind farms joint sharing energy storage participating in primary frequency regulation based on chance-constrained programming is established.Finally,an improved p-effective point method based on a fast Fourier transform to quickly solve the probability distribution of joint variables is proposed to transform the chance-constrained programming into deterministic programming through mathematical analysis.Then Cplex is called by Yalmip to realize the fast solution of the model.The results of the example show that the proposed model and method can effectively improve the effect and benefit of wind-storage frequency regulation,and have higher solution efficiency.
