Integrated Energy Planning Considering A Reward And Punishment Ladder-type Carbon Trading And Load Uncertainty

With the continuous increase in energy demand and environmental pressure,in recent years,natural gas exploitation technology,electricity-to-gas technology and combined heat and power technology have developed rapidly,which promotes the coupling of power system and natural gas system.The power system and natural gas system have changed from independent planning and operation to joint planning and operation.Therefore,joint planning of integrated energy system is necessary.In this paper,in the integrated energy system energy planning model,a reward and punishment ladder-type carbon trading cost was introduced.And analyzes the impact of load demand uncertainty on energy planning,a two-stage robust planning model of the integrated energy system that considers a reward and punishment ladder-type carbon trading cost and load uncertainty is established.The specific research contents are as follows:First of all,the energy center coupling model was analyzed.A reward and punishment ladder-type carbon trading cost model suitable for integrated energy systems was constructed,and the uncertain factors and methods in integrated energy planning were analyzed and introduced.Secondly,considering the low carbon and economy of the system comprehensively,a reward and punishment ladder-type carbon trading cost model was introduced into the integrated energy system planning model.The discrete bacterial colony chemotaxis algorithm is used to solve the model.The simulation of a 9-node energy center test system is performed in 4 scenarios,the impact of the reward and punishment ladder-type carbon trading cost on the planning results is analyzed,the validity of the model is verified,and the impact of carbon trading prices on system operation and planning is analyzed.Finally,the two-stage robust optimization model is used to deal with the uncertainty of electrical load,thermal load and electro-thermal transferable load.The integrated energy two-stage robust planning model considering the reward and punishment ladder-type carbon trading cost was established.Then the Benders decomposition method is used to solve the model,the simulation of a 9-node energy center test system is performed in 4 scenarios,the effects of the robust model and the reward and punishment ladder-type carbon trading cost on the simulation results were analyzed,and the model was verified to be reasonable.
