The Planning And Operation Of Integrated Energy Systems Under Load Uncertainties

With the increasing attention to new energy power generation,related technologies and concepts have also developed rapidly.In order to promote the widespread application of new energy technologies and solve their intermittent and instability problems,integrated energy systems have been increasingly developed and become an important solution to the problems caused by the connection of new energy to the power grid.This article aims to build a regional 100%new energy system using integrated energy technology.First,the first chapter introduces the research status of integrated energy systems at home and abroad,and summarizes important literature,including the current status of energy,research purposes,and article structure.The second chapter introduces the technical background of integrated energy,including distributed generation,smart energy networks and energy integration methods.In addition,the design principles,modeling methods and simulation techniques of integrated energy generation systems are also presented in this chapter.The third chapter designs the concept map of 100%new energy system and realizes the safe and stable operation of the new energy system through energy integration and energy storage technology.First,by designing a single energy system and reasonably integrating them,this chapter designs a complete integrated energy system to achieve clean energy consumption.Based on this system,the mathematical model of the energy router is also shown in this chapter to realize the interaction of different energy systems.In addition,in order to measure different operating modes,this chapter establishes a multi-objective operating mode,including two objective functions and multiple constraints.Chapter 4 proposes a new investment planning method for long-term planning of integrated energy.Considering the uncertainty of various energy load growth,this chapter uses the concept of real options and pricing methods to quantify and compare the value of different investment methods to obtain specific investment decision methods.In the long-term planning phase,the strategic flexibility of investments provided by new energy technologies can help planners adjust their initial investment decision-making strategies based on future information.Within the investment time limit,delaying investment or increasing expansion opportunities may provide investors with great project value.This chapter uses contingent claims analysis method,and on this basis,proposes investment pricing methods to help investors make clear decisions.The proposed investment decision-making method can use the real option method to quantify the value of different flexible investment schemes.In order to test the feasibility of the proposed system and operation mode,Chapter 5 uses EnergyPLAN software to simulate the examples and analyze the output results.Finally,the sixth chapter summarizes and evaluates the research work of this paper and summarizes the possible work in the future.
