Abstract :

The increasing electrical demand led the research toward adopting self-sufficient technology. The concept of microgrid (MG) emerged out to be an exemplar idea to accommodate distinctive characteristics of distributed generation (DG) to provide reliable and sustainable electrical energy. The conservative voltage reduction (CVR) is a viable scheme, which is utilized in distribution sector to lessen the consumption of energy. The chapter emphasizes on the adaptation of CVR scheme to preserve power in the stand-alone MG with the application of voltage–current droop mechanism. The applicability of voltage–current droop in performing demand side management (DSM) is a prospective area to be explored. Further, the chapter discussed about devising modified voltage–current droop method which facilitates smooth computation of droop in the multifeeder network and also it ensures accurate sharing of power among DGs. Moreover, the determined droop parameter for voltage–current droop plays a crucial role in the power saving phenomena to realize DSM. The chapter aims to explore the area of curtailing the consumption of power of stand-alone MG by effectively minimizing the voltage parameter according to the set standard. The validation of the designed control scheme is being analyzed on MATLAB with the implementation on a five-bus test system and controller’s transient behavior is evaluated through three phase fault condition. The competency of the proposed mechanism is depicted through comparing the simulation results with conventional P-f/QE droop.
