摘要
研究能源互联网背景下,需求侧直接负荷控制的集群空调负荷(air condition loads,ACLs)在消纳风电功率中体现的虚拟储能特性和相应的储能容量。采用蒙特卡洛模拟方法验证改变设定温度的集群ACLs的储能特性;建立了双耦合线性偏微分方程组的集群ACLs状态空间模型,提出了以风电–储能–集群ACLs联合系统出力为滑模面的变结构滑动模块跟踪控制策略来实现联合出力的平滑输出;仿真改变设定温度时,集群ACLs消纳实地风电场输出功率情景,结果表明所提方法能够消纳低时间常数滤波的风电出力,设定温度变化在±1℃内,其储能容量达到90 MW?h以上。该方法可为能源互联网中能量合理调配、减少储能配置方面提供新的技术途径。
The paper studied the virtual storage features and energy storage capacity of aggregated air condition loads（ACLs） of demand side reflected from wind power accommodation under the background of the energy internet. The energy storage features of changed set temperature aggregated ACLs was verified by Monte Carlo simulation, The aggregated ACLs state space model was established on the base of two coupled partial differential equations, and the power of wind power-energy storage-aggregated ACLs union system used as the sliding surface of power tracking sliding mode variable structure control strategy was proposed which can realize the smoothing output of union system power. At last, the aggregated ACLs accommodation of real wind power plant was simulated by changing the set temperature, the result shows that the proposed method can accommodate the wind power filtered by a low time constant, and the set temperature changed within ±1 ℃, the energy storage capacity can reach more than 90 MW？h. The method paves the path for the energy reasonable allocation in energy internet and reducing of energy storage allocation.
