Impact Analysis of Demand Side Management for Maintaining the Voltage Profile of Distribution System

Abstract

Lowering real PL and maintaining an appropriate VP are the two key concerns that distribution system utilities are worried about. Several techniques such as capacitor, DG, DFACTS allocation, and network reconfiguration have been suggested by the researchers to achieve this goal. One of the methods that can help raise the network VP to a reasonable level and reduce PL is the DRP, which is customers’ response to changing prices of electricity, urging them to lower their usage during periods of peak load. Consequently, in this study, DRP has been used to raise the network VP and manage the system loss. Load modeling is conducted utilizing the concept of demand elasticity with respect to price. Hourly variation of the seasonal load is considered. The impact of DRP on an hourly variation of active–reactive load and each line flows has been analyzed. To determine the VP and electrical PL of the test system, BFSLF method is used with the amended load data once the modified demand based on DRP has been received. The DRP that is utilized for analysis of the distribution network is time of use. The method under consideration is assessed on a RDS, specifically the standard IEEE 33-bus. It is seen that significant losses are reduced, along with VP improvement. The distribution utilities may find the suggested technique to be of utmost significance to enhance the VP along with the reduction of loss. Also, the technique is beneficial to utility as well as the customer, thus maximizing social welfare. © The Institution of Engineers (India) 2024.
