Low Carbon Economic Dispatch Of Integrated Energy System Considering Hydrogen Energy Utilization And Multi-agent Benefits

In light of increasing environmental pollution and the ongoing global climate crisis,adoption of more sustainable and operational energy solutions is gaining ground.The increasing consumption of traditional energy has led to increased pressure on energy supply,and it has also brought a huge burden to the environment.In this context,integrated energy systems are considered to be an effective solution that can play a positive role in improving energy efficiency and reducing environmental pollution.From the perspectives of hydrogen energy utilization and multi-agent benefits,this paper conducts a series of research on the low-carbon economic scheduling of integrated energy systems.The specific content is as follows:First of all,the introduction part systematically summarizes the development status of the integrated energy system,and sorts out the research status of the integrated energy system from various aspects.Secondly,in the second chapter,the basic framework of the integrated energy system is described,the working mechanism and operating characteristics of the common equipment in the integrated energy are analyzed,and the internal energy coupling equipment is mathematically modeled.Then,in order to further guide the system towards low-carbon and economical operation,this paper introduces a hydrogen energy supply system composed of electrolyzers,hydrogen fuel cells,methane reactors,and hydrogen storage tanks in the comprehensive energy system,and constructs a hydrogen energy coupled system.Mathematical models of energy equipment.A lowcarbon dispatching model of an integrated energy system is constructed with the optimization goal of minimizing the sum of operating cost,energy storage aging cost,demand response subsidy cost and stepped carbon transaction cost.By setting up different scheduling scenarios and carrying out numerical simulations,the influence of factors such as reward and punishment ladder carbon trading mechanism,comprehensive demand response strategy,and hydrogen energy coupling system on the optimal scheduling of the system are studied respectively.The results show that the proposed model can effectively realize the comprehensive energy system.Economical and low-carbon operation.Finally,considering that in practical applications,the operation of integrated energy systems involves multiple stakeholders,such as energy suppliers,energy service providers and end users,etc.,this paper proposes an IES supplier-service provider two-tier optimized low-carbon scheduling Model.First,build an integrated energy system including gas turbines,waste heat boilers,electric boilers,renewable energy,electric heating loads and electric vehicles,and divide it into three stakeholders: IES suppliers and two IES service providers.Suppliers include energy supply equipment,and service providers provide users with electric heating loads and electric vehicle charging and discharging.In order to coordinate the interests of the upper and lower levels,a dynamic electricity price mechanism is proposed.This mechanism formulates dynamic electricity prices according to the consumption of renewable energy in the upper-level suppliers,and passes the electricity prices to the lower-level service providers.The lower-level service providers will adjust energy consumption according to changes in electricity prices.plan,and feed it back to the upper-level suppliers,and iterate repeatedly to realize the coordinated and optimized operation of the upper and lower levels.Through the comparative analysis of the calculation example,it can be known that the proposed dynamic pricing mechanism can effectively guide the electric heating load power consumption plan and the charging and discharging scheme of EV.At the same time,this mechanism can encourage users to actively participate in comprehensive demand response,improve the utilization rate of renewable energy in the upper layer,and effectively reduce the operating costs of the upper and lower layers.In addition,the economic and environmental benefits of the proposed model are further analyzed,and it is verified that it can achieve lowcarbon economic operation.
