Optimal Placement of the Demand Response Program for Voltage Static Stability using TLBO Algorithm

According to the definition of Energy Department, demand response is the ability of domestic, industrial, and commercial consumers to use electrical energy to modify their consumption patterns at peak time to affect the price and reliability of the grid. The power grid voltage static stability could be improved to a satisfactory level using the demand response. For this reason, in this research, this device was used to improve the static stability of the grid voltage. In order to improve the objective functions, the normal state of the grid is considered. Normal mode is considered as the normal state of the grid, which provides the grid in its stable state without any failures in equipment. The optimization algorithm in this study is the TLBO algorithm. The problem of optimal allocation of demand response programs is solved to achieve the best value of the objective function of the grid voltage static stability. The location, the active and reactive power for which the best static voltage stability is achieved in the grid, is presented as an optimal response. The simulation results showed that the best place for this program to improve the static stability of the grid is bus No. 8.
