基于事件驱动的需求侧电池储能二次控制

Event-driven Secondary Control of Demand-side Battery Energy Storage

为解决需求侧电力资源的灵活调控问题,提出一种基于事件驱动的分布式固定时间二次控制方案。该方案针对需求侧电池储能系统(BESSs),旨在调控其能级、功率和频率以实现对需求侧电网中频率和功率随机波动的补偿。考虑到需求侧仅有部分电池可以接收主电网信息,采用分布式控制算法调控每个电池的能级、有功功率和频率,实现了BESSs在固定时间内的能级平衡、有功功率共享和频率调节。此外,该方案引入了事件驱动机制,无需连续通信和频繁切换控制信号,从而显著降低了BESSs调控过程中的能量消耗。最后,仿真实验结果表明,提出的控制方案能够在较低的能量消耗下实现对需求侧电力资源的快速调控。

In order to solve the flexible control problem of demand-side power resources,an event-driven distributed fixed-time secondary control scheme was proposed.This scheme is aimed at the demand-side battery energy storage system(BESSs),which is designed to adjust its energy level,power and frequency to compensate for random frequency and power fluctuations in the demand-side grid.Considering that only a subset of batteries on the demand side can receive the information of the main grid,the study achieves energy-level balancing,active power sharing,and frequency regulation of BESSs within a fixed time by using a distributed control algorithm to regulate the energy level,active power,and frequency of each battery.In addition,the scheme introduces an event-driven mechanism that eliminates the need for continuous communication and frequent switching of control signals,thus significantly reducing energy consumption during BESSs regulation.Finally,the simulation results showed that the proposed control scheme can achieve rapid regulation of demand-side power resources with low energy consumption.
