Abstract :
This paper describes a brokerage model for multi-period generation schedule in the interconnected power system based on the nonlinear formulations. The security constraints and transmission losses are considered in this model. We use nonlinear programming to get the most profitable value according to the power flow in the transmission net and the marginal cost offered by clients. The transaction schedules for a 6 bus system with a pump-station and a 30 bus system are calculated to demonstrate the effect of the proposed model
