Control strategies of battery energy storage system participating in peak load regulation of power grid
摘要
现有针对电化学储能在电网调峰领域的研究缺乏在不同负荷场景下不同控制策略的应用对比
使得削峰填谷控制策略的选择缺乏理论依据。本文结合已有相关研究和对储能系统特性的分析
首先在考虑电网负荷、电池功率、电池容量等约束条件下
建立了以削峰填谷效果为目标的储能系统优化模型;然后在现有典型控制策略的基础上
提出了电池储能参与电网削峰填谷的恒功率充放电控制策略和功率差控制策略;最后
以某地区实际负荷数据为例
结合电池储能装置自身充放电特性
通过仿真对比了2种控制策略的优缺点
验证了考虑实际约束条件的功率差控制策略具有更优的削峰填谷效果。
Abstract
The current research on electrochemical energy storage in the field of power grid peak-shaving is lack of application comparison between different control strategies in different load scenarios
which makes the selection of peak-shaving and valley-filling control strategy lack of theoretical basis. In this paper
the optimal model of energy storage system is established based on the existing typical control strategies
and the constant power chargedischarge control strategy and the power difference control strategy are proposed. Finally
taking the actual load data of a certain area as an example
combined with the charge-discharge characteristics of the battery energy storage device itself
the advantages and disadvantages of the two control strategies are compared by simulation
and the power difference control strategy considering the actual constraints is verified to have a better peak-cutting and valley filling effect.
