Electricity trade will eventually evolve into some type of an electronic commerce structure, facilitated by a group of collaborative software agents that work according to standard regulations and strict operational and security constraints. This paper presents developing agents for electricity trade markets. We follow a standard agent design requirements and standard agent communication protocols. The results of the test case show that agents facilitate electronic trade and drive the market price closer to the marginal cost of generation supply and far away from the estimated Cournot price.
