Study on model of power grid operation security cost in market environment
With the impact of interruptible load (IL) to power system and the security of power grid, this paper points out that IL is one of the security providers. Then the model of power grid operation security cost is presented. The security cost consists of the generating reserve cost, the IL cost, the rescheduling cost and the expected system instability cost. A lingo program is used to optimize the model. The rationality and feasibility of the model here are demonstrated by IEEE30 bus power system.
