ELECTRICITY MARKET SIMULATOR USING MATLAB

In deregulated electricity industries, an electricity market simulator is one of the tools which can be used by market participants and administrators to analyze market behaviors, to formulate optimum bids, and to investigate different market structures. This paper presents the development of an elec-tricity market simulator that is designed to imitate the Australian National Electricity Market. The simulator is developed in MATLAB and is composed of four main components: generators, loads, pricing engines, and database interfaces. The simulator generates regional spot prices, individual dispatching of generators and transmission flows/losses, all of which are automatically saved in a database at each dispatch interval. Access to historical market data through the database interface is crucial in the formulation of bidding strategies. Some interesting results of the simulation that show the effects of transmission losses and congestion, and different market behaviors are also presented. 1
