Analysis of the Multi-objective Competitive Relationship in the Comprehensive Utilization of Water Resources in the Upper Reaches of the Yellow River considering the Hydropower-Wind-Photovoltaic Coordinated Operation
Analysis of the Multi-objective Competitive Relationship in the Comprehensive Utilization of Water Resources in the Upper Reaches of the Yellow River considering the Hydropower-Wind-Photovoltaic Coordinated Operation
With the increasing demand on hydropower to compensate and regulate the wind and photovoltaic power,the competitive relationship on water resources in the upper reaches of the Yellow River becomes more complex.A medium to long term hydropower-wind-photovoltaic collaborative operation model is established.Combinations of typical years and different wind and photovoltaic power outputs are studied.The competitive relationship and its causes between each group of objectives under different wind and photovoltaic power proportions are obtained,especially for ice prevention and irrigation periods.The results show that the large outflow in the early ice flood period leads to a decrease in available water amount in the subsequent period.Hydropower needs to compensate the unstable wind and photovoltaic power out-puts,resulting in the inability of the outflow to meet the irrigation demand during the irrigation period.The competitive relationship in typical years becomes more complex with the decrease of the incoming water flow.Also,the competitive relationship under different wind and photovoltaic power proportions becomes more complex with the increase of the pro-portion.The results can be useful reference for the multi-objective comprehensive utilization of water resources.
