DEVELOPMENT OF EDUCATIONAL WEB-BASED SIMULATOR FOR THE ELECTRICITY SPOT MARKET IN KOREA

This paper discusses the development of the educational simulator for the electricity spot market in Korea. In the developed simulator, lecturers can set information related with market and market entities and students can bid and examine the market with lecturers. The interaction between lecturers and users can be much enhanced via the web-based programs which result in the student's learning effectiveness on an electricity spot market. However the difficulties for developing web-based application programs are that there can be the numerous unspecified users to access the application programs. To overcome the aforementioned multi-users problem, we have provided the effective system architecture, the modelling of application programs, and database efficiently and effectively to manage the complex data sets. The developed application program is composed of the physical three tiers where the middle tier is logically divided into two kinds of application programs. The divided application programs are interconnected by using the Web-service based on XML (Extended Markup Technology) and HTTP (Hyper Text Transfer Protocol) which make it possible the distributed computing technology.
