Study on the Architecture of National Electric Power Supply and Demand Simulation System

It is significant to establish national electric power supply and demand simulation system. This paper aims at studying the architecture of the simulation system from three respects: software structure, database platform and system functional module. Firstly, in the case of software structure, the simulation system is designed to be based on the mixed pattern of B/S (browser/server) and C/S (client/server), and its structure is a multilayer distributed structure, including presentation layer, Web service layer, application service layer and data service layer; secondly, the database platform of the simulation system is classified into business database, achievement database and multimedia database; thirdly, concerning system functional module, the system consists of five modules: current situation analysis of power supply and demand, forecast of power supply and demand, early warning the imbalance of power supply and demand, important relationship of power supply and demand, and policy simulation.
