含氢储能的多源联合发电系统调度研究

风电和光伏发电具有间歇性和随机性，为了降低在多源联合发电系统中的弃风弃光率，采用含氢储能系统和火电机组配合来平滑风电和光电机组出力。文中以系统运行成本最小和弃电惩罚成本最小为目标，以系统功率平衡、火电机组出力和爬坡、热备用、风电和光电出力及储能系统储氢罐容量、电解槽和燃料电池功率等为约束条件构建了多源联合发电系统日前调度模型。通过YALMIP工具箱对模型进行编程，并调用CPLEX对编写的程序进行求解。对含有风电、光电、火电机组以及储能系统的多源联合发电系统进行算例分析，通过对比有无储能系统的弃风弃光量和系统总运行成本，证明了含氢储能系统可以有效降低系统的弃风弃光率，并提高系统的经济性。

Research on Dispatching of Multi-Source Combined Power Generation System Containing Hydrogen Energy Storage

Wind power and photovoltaic power generation are intermittent and random. In order to reduce the abandonment rate in the multi-source combined power generation system, the hydrogen-containing energy storage system and the thermal power unit are used to smooth the output of wind power and photovoltaic units. This study aims to minimize the operating cost of the system and the penalty cost of power abandonment. A day-ahead scheduling model of multi-source combined power generation system is constructed with the constraints of system power balance, thermal power unit output and ramping, hot backup, wind power and photovoltaic output, hydrogen storage tank capacity of energy storage system, electrolyzer and fuel cell power. The model is programmed through the YALMIP toolbox, and CPLEX is called to solve the programmed program. A case study of a multi-source combined power generation system containing wind power, photovoltaic, thermal power generation and energy storage systems is carried out. By comparing the amount of abandoned wind and light with or without an energy storage system and the total operating cost of the system, it is proved that the hydrogen-containing energy storage system can effectively reduce the rate of abandoned wind and light and improve the economy of the system.
