摘要

针对光储氢微网系统运行时系统内部功率协调分配、切换平滑度以及电压稳定性等问题,提出一种考虑系统不同需求指令的功率分层协调运行策略。以提升系统稳定性、光氢系统结合度以及平滑运行为目的,搭建光储氢微网系统仿真模型,一方面,通过分层控制实现系统指令层与被控层之间的协调运行,并以上网电价为判断指标,保障系统经济性运行;另一方面,基于系统运行模式将系统运行工况分为8种,并通过多功率协调控制策略使得光储氢微网系统能够稳定运行、工况切换平滑以及母线电压稳定。最后通过仿真验证所建模型与控制策略的正确性与有效性。

Abstract

For the problems of coordinated power distribution, switching smoothness and voltage stability within the system during the operation of photovoltaic energy storage hydrogen energy micro-grid system, this paper proposes a power hierarchical coordinated operation strategy that considers the different demand commands of the system. A simulation model of the photovoltaic energy storage hydrogen energy micro-grid system was built with the aim of improving system stability, photovoltaic hydrogen system integration and smooth operation, On the one hand, the coordinated operation between the command layer and the controlled layer of the system is realized through hierarchical control, and the on-grid electricity price is used as a judgment indicator to guarantee the economic operation of the system; on the other hand, the system is categorized into eight operating conditions based on the system operating state, and the multi-power co-ordination control strategy enables the stable operation, smooth working condition switching and stable bus voltage of the optical storage and hydrogen micro-grid system. Finally, the correctness and effectiveness of the built model and control strategy are verified by simulation.
