实现跨日消纳风电的电储能日前优化调度策略
Optimal dispatch strategy of electricity storage for realizing cross-day wind power accommodation
摘要
Abstract
In the high proportion of wind power system,wind power generation has significant intra-day volatility,and the existing electricity storage dispatch strategy based on the charging and discharging balance in the cycle cannot realize the cross-day consumption of wind power by electricity storage resources.Therefore,a solution strategy is proposed to convert the net storage energy of electric energy storage at the end of the day into equivalent coal consumption,which is deducted in the objective function of the optimal scheduling model,and the value range of the conversion coefficient of equivalent coal consumption is reasonably determined,so that the optimal scheduling can not only make full use of electric energy storage to store the surplus wind power in the day for the next day,but also avoid the storage of thermal power in the day.The example takes a provincial power system with complex power supply structure in the north as the object for calculation and analysis,and verifies the effectiveness of the proposed strategy for the cross-day consumption of wind power.Compared with the scheduling strategy of intra-day charging and discharging balance of electric energy storage,the wind power abandonment rate is effectively reduced.Compared with the scheduling strategy of power abandonment penalty,the cost and benefit of consumption are reasonably compromised,and the overall energy consumption of scheduling is lower.关键词
