Design and Application of Decision-Making System for Electricity Purchasing Agency Transaction of Grid Enterprises

As a characteristic product of China's electric power market reform, the electricity purchasing agent service of grid enterprises is still in the elementary research stage on the whole and is challenged by complicated transaction rules, high transaction frequency, difficult transaction decision-making, and other problems. Therefore, it urgently requires establishing a decision-making system for electricity purchasing agency transactions to promote the intelligent decision-making of electricity purchasing agent services. This paper firstly summarizes a complete process of electricity purchasing agent service of grid enterprises by reviewing the whole process from pre-transaction, in-transaction to post-transaction; secondly, it designs an intelligent, practical, scientific, efficient, agile, and iterative decision-making system for electricity purchasing agency transaction, establishes an overall structure of six key functions (such as consumer management and electric power and energy monitoring) featuring headquarters management - provincial operations and internal-external data interaction; and finally, it discusses key technologies for prediction of consumer power consumption, preferential power sources matching and tariff prediction involved in the system development process, introduces the outstanding results of the system applied in large-scale projects in China, and explores the direction of future research.
