| Electric power plays a crucial role in a country,playing an irreplaceable role in ensuring industrial and agricultural production,military and national defense fields,and ensuring people’s livelihoods.Electricity trading refers to the activity of buying and selling electricity goods and services.With the continuous promotion of the power industry and the opening of the electricity sales side,the power trading market has gradually become the trend of the development of the current power industry and the market is more and more active.It is very necessary to establish the simulation system of electric power trading and study the bidding mode and price formation mechanism of electric power trading.The purpose is to promote the progress of the reform of electric power market immensely,ensure the stability of trading market,cut down the operation risk of trading market,and promote the construction and gradual improvement of electric power market.This paper designs and develops a power trading simulation system,and the main research contents include:Fristly,analyze the requirements of the power trading simulation system,and design the system from three aspects:overall architecture,functional module design,and database design.Then,complete the development and testing of the power trading simulation system according to the system design.At the demand analysis level,analyze the functional requirements of the system in the form of use case diagrams,and describe the non-functional requirements of the power transaction simulation system in text form.The overall architecture design mainly includes two parts:logical architecture and technical architecture.The logical architecture adopts MVC,and the technical architecture adopts Vue+ElementUI+SpringCloud framework.In terms of functional module design,the realized functions are designed in the form of a flowchart.Database design is analyzed from two aspects:conceptual structure design and data table design.Among them,conceptual structure design uses E-R model to represent the relationship between entities,and data table design mainly designs the fields,types,and lengths of tables.Secondly,in view of the current problems of incomplete simulation models and algorithms for electricity trading,such as the inability to provide pricing decision support for market members,this paper takes market entities such as power sellers and power buyers in the electricity market as research objects,analyzes the transaction objectives of both parties,and uses Rubinstein bargaining to establish a mathematical model for bilateral negotiated transactions based on relevant transaction rules Using RE algorithm to construct a mathematical model for centralized bidding transactions,using game theory to establish a mathematical model for listing transactions,and using simulation data to analyze the model to verify the authenticity and reliability of the model. |
