风电-氢储能与煤化工本地多能耦合系统监控系统设计与实现

Design and Achievement on the Monitoring System of Wind Power-hydrogen Storage and Coal Chemical Multi-function Coupling System

针对风电系统居高不下的弃风率以及对电网稳定可靠性影响越来越大等问题,本文基于风电—氢储能与煤化工多能耦合系统能量广域协调控制架构,研究了本地WP-HES&CCMFCS监控系统。首先,设计了储能装置集中式并网的本地WP-HES&CCMFCS的物理架构,并提出了能量分配控制策略,使风电系统输出较为平滑的功率的同时有效结合煤化工系统可应用电解水制得氢氧的特性提高电网的综合风电消纳水平。在此基础上设计了基于MCGS的本地WP-HES&CCMFCS监控系统,并对监控系统进行了仿真运行。监控系统输入、输出功率,系统储能状态变化规律以及电磁阀状态跟储能状态对应关系等仿真结果表明所提出的能量分配策略是正确有效的。

In view of such problem as high abandonment of wind rate of wind power system and remarkable influence on the grid stability,in this paper,the monitoring of the local wind power-hydrogen energy storage and coal chemical multi-functional coupling system(WP-HES & CCMFCS) is studied based on the energy wide range coordination control framework of WP-HES & CCMFCS. Firstly,the physical structure of local WP-HES & CCMFCS for integrated connection in the energy storage device is designed,the energy distribution control strategy is proposed in order to keep smooth power of the wind power output and,at the same time,to improve the comprehensive wind power use level with the hydrogen-oxygen feature made of brine electrolysis with effective combination of coal chemical system. On this basis,the local WP-HES & CCMFC monitoring system is designed and simulation operation of the system is performed. It is proved that the proposed energy distribution strategy is correct and effective by such simulation results as input and output of the monitoring system,energy status variation rule of the system and the corresponding relations between the status of solenoid valve and the energy storage status,etc.
