Simultaneous Implementation of Time of Use Demand Response and Security Constraint Unit Commitment

The growing need of energy sources especially in industrial countries and the shortage of the fossil resources cause a great concern in many countries. Considering that in some periods of the day the energy price is increased, Demand side management is one of the solutions that is implemented. The major change in demand side management is consideration of consumer's response to energy price variations. This paper investigates the effect of demand response implementation on cost reduction in stochastic security constraint unit commitment. Uncertainties in power system such as transmission lines and power plants outage is considered in the paper Considering that the simultaneous implementation of stochastic security constraint unit commitment and demand response is a complex and nonlinear problem that contain Continuous and discrete variables, the mixed integer programming is being used. Proposed method is simulated in simple 3 bud system and IEEE RTS 24 bus system and the results analyzed in the paper.
