This paper presents a contrived framework that accompanies the power quality improvement (PQI) and demand- side management (DSM) in the case of recurring voltage-related problems. The illustrative implementation of the proposed framework necessitates two antecedents. First, a comprehensive mathematical formulation of the electrical power for a dynamic voltage restorer (DVR) is presented. Second, a model is developed to analyze the energy exchange during the voltage disturbances. Afterwards, the performance of a DVR system is simulated and a scrutinization is accomplished about the effect of power exchanged by a DVR with distribution system on the load factor. Meanwhile, a modified mathematical model of demand response (DR) is developed to derive the different DR methods with the purpose of load profile improvement (LPI). The simulation results reveal that the DVR operation may decrease the load factor from +3.56% to − 3.20% of the usual load factor. Furthermore, in some situations, the DR outcomes might be obliterated by PQI. The implementation of proposed framework demonstrates the load factor can be enhanced up to 7.46% by proper DR strategy adoption.
