摘要

基于随机规划思想和风险决策理论，提出一种计及风险备用的风储联合运行系统广域协调调度方法。协调模型采用双层优化方法实现发电计划优化子问题和备用容量优化子问题的分解协调和迭代求解，降低了随机机组组合模型的计算规模和求解难度。外层优化计及风电波动性采用确定性机组组合模型计算日前发电计划;内层优化基于条件风险价值计算风电预测误差引起的系统风险备用容量，并采用所提出的风储协调策略实现多风电场储能系统之间的协调调度以降低系统备用需求。采用增加了2个风电场的IEEE 30节点系统进行仿真，分析了大规模风电并网系统中储能系统的最优应用模式，并验证了所提协调调度策略在提高风电消纳能力方面的优越性。

Abstract

This paper presents a risk-constrained coordinative dispatch method for energy storage systems in the large-scale wind-storage systems based on stochastic programming and the risk decision theory.The purpose is to figure out the best application mode and optimal dispatch method for large-scale energy storage systems in power systems with high penetration of wind power.The stochastic unit commitment model is re-formulated as a bi-level optimization model，with a deterministic unit commitment model and a reserve risk decision model as its external level and internal level，respectively.Conditional value-at-risk（CVaR）is adopted to calculate the risk reserves and coordinate the bi-level models.A novel dispatch method used for coordination between wind power，energy storage and conventional thermal units is also proposed.An IEEE30-bus system with two actual wind farms is used for verification purposes.
