Demand Response Programs And Implementation Optimization Of Hybrid Microgrid Based On The Equilibrium Of Economic And Environment

China’s economic and social development is still driven by a large number of high-carbon energy sources,mainly coal,with serious environmental pollution problems and energy demand will continue to increase.China is facing the reality of "rich coal,poor oil,and low gas",and the high dependence of petrochemical energy on foreign sources has put forward new requirements for the development of the country’s energy industry.In order to effectively alleviate the petrochemical energy crisis,environmental pollution problems and ensure energy security,the hybrid energy microgrid that combines traditional energy and renewable energy has become one of the most important industrial forms for the development and utilization of renewable energy.In order to optimize the energy structure and alleviate environmental problems,it is necessary to continuously increase the consumption of renewable energy,which also makes the utilization rate of renewable energy in the hybrid energy microgrid continue to increase.Renewable energy power generation has the characteristics of intermittent and volatility,which will bring challenges to the stability and reliability of microgrid industry operations,and increase the complexity of grid economic dispatch.Relying only on the adjustment and optimization of the power supply side to ensure the balance of power supply and demand is not only difficult but also costly.Therefore,it is necessary to activate the potential of the demand side to solve this problem collaboratively.Demand response is one of the important economic strategies of power demand-side management.It can increase the demand-side load regulation potential based on various electricity prices and incentive measures,and promote the safe,economic and sustainable operation of hybrid energy microgrids.Sustainable development also plays an important role in promoting.However,different demand response programs will affect the benefits of hybrid microgrids to varying degrees in different aspects.Therefore,it is of great practical significance to study the demand response programs and implementation optimization for the hybrid microgrid,taking into account the benefits of the two major industries,the economy and the environment.This paper studies the impact of demand response programs on the operational benefits of hybrid energy microgrids.Aiming at the problem that regional hybrid energy microgrids can adopt suitable demand response programs,this paper proposes hybrid microgrid demand response programs and implementation optimization methods.First,it analyzes the characteristics of microgrid and demand response,in terms of China’s development status and potential,related policies,etc.,it is clear that China has the conditions and urgent needs to implement demand response programs in microgrids.Based on multi-objective planning and multi-criteria decision-making methods,starting from three aspects of economy,environment,and renewable energy utilization,a multi-objective optimization model of hybrid microgrid operation benefits considering the impact of the implementation of demand response programs on load is established,using TOPSIS algorithm draw up the optimal plan of hybrid microgrid operation efficiency under each demand response program.On this basis,combined with the preference of the power supply and demand sides for the selection of demand response programs,a multi-criteria decision model based on load factor,satisfaction degree and energy saving is established to rank the implementation effects of different demand response programs.Then,work out the best implementation plan.Finally,taking the microgrid project in Erenhot,China as an example,eight kinds of demand response programs suitable for my country’s national conditions were selected.According to the optimization results,the practicability and effectiveness of the method are illustrated.The research results show that the optimization program obtained by this method can effectively cope with the peak-valley effect of grid load and help balance the supply and demand to improve the efficiency of the power generation system.Besides,it can meet the economic operation of the hybrid energy microgrid and improve the environmental benefits and renewable energy.This research can also provide certain theoretical and methodological references for the design of demand response programs of relevant research institutions,microgrid operators,and relevant government departments and the formulation of economic policies for the renewable energy industry.
