摘要

为实现孤岛交直流混合微电网群的稳定优化运行

提出一种多级功率管理策略。该策略包含两部分:多级功率分配控制策略和多级功率互动管理策略。多级功率分配控制策略通过功率自治级、功率互助级和功率平衡级等三级控制

实现系统功率的分散管理。考虑系统互联通信正常和通信故障2种运行情况

提出一种适用于交直流混合微电网群的多级功率互动管理策略

实现各功率分配级之间合理的切换管理

保证孤岛系统的供电质量

并减少系统功率互动损耗。设计事件触发控制器

实现多级功率互动管理策略仅在事件触发时刻进行数据交换

降低系统对通信网络的要求。最后

通过MATLAB/Simulink仿真平台验证了所提控制策略的有效性。

Abstract

To realize the stable and optimal operation

a strategy of multi-level power management is proposed for the islanded AC/DC hybrid microgrid cluster. The proposed strategy consists of two parts: distribution control strategy and interaction management strategy of multi-level power. Through the three levels of power autonomy

power interaction and power balance

decentralized management of system power is realized by the distribution control strategy of multi-level power. Considering the two operation cases of normal communication and communication fault

an interaction management strategy of multi-level power is proposed for AC/DC hybrid microgrid cluster

which can realize reasonable switching management between power distribution levels. Meanwhile

the proposed strategy can ensure the power quality of the islanded system

and reduce interaction loss of system power. To lower the system requirements for the communication network

the event-triggered controller is designed to realize data exchange only at the moment of the event triggering. Finally

the effectiveness of the proposed control strategy is verified by MATLAB/Simulink simulation platform.
