Abstract

Abstract:

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.

Key words: hydrogen-containing energy storage system, multi-source power generation system, day-ahead dispatch, wind power and photovoltaic output, abandonment rate of wind and light, economic dispatch, YALMIP, CPLEX
