The Transaction Base in the Electricity Spot Market: The Case Study of Isfahan Electricity Market

In most of the developing countries، particularly in Asian countries، the initial step of electricity industry restructuring has begun by spot market design. In addition، electricity industry، all around the world، is approaching competitive markets. Meanwhile there are many unanswered questions including deregulation mechanism. In this new framework، producers are considered as private companies which are responsible for their decisions. This paper presents a regional model for the deregulated electricity market where producers trade the electricity with distribution utilities based on spot prices. A mathematical programming model is used to calculate an appropriate base for electricity market transactions. The model has been implemented while different power plants produce electricity and demand fluctuates permanently. The model minimizes total variable costs subject to generation and demand constrains. Isfahan electricity market is considered as empirical evidence. To run the model، General Algebraic Modeling System (GAMS) software has been used.
