Optimization model of purchasing interruptible load for network congestion restricted dispatch during the peak load time periods

Interruptible load management (ILM) is one of the demand response incentives. It is good to the reliability of the power system. During the peak time of the power system, there are always congestion restrictions. Based on the active power dispatch, an optimal IL purchasing model including hybrid generation, network and demand side restrictions was presented. This model not only puts emphasis on the network congestion capacity restriction but considers the influence of pre-informed time and the interruption duration period and the geographical position on network loss. The binary version of the particle swarm optimization (BPSO) method was used to solve this model. The simulation result shows that the model is fit for using IL in peak load congestion restricted dispatch in developing power market.
