Conservation voltage reduction in a dynamic loads system

Conservation voltage reduction (CVR) is an efficient energy saving method and it is becoming popular among electrical utilities. For this project, I plan to model and test a 24.9kV, IEEE 34 distribution system in PSCAD. Firstly, I do the simulation with ZIP load model and got the different CVR factor with different load types. Secondly, the loads will be replaced by the dynamic loads. The active power and reactive power of this load are time-varying. Comparing the results for these cases, we can know the changes in voltage, active power and reactive power as the voltage source dropped down. Besides, from the graphs, we can obtain the changing curve of time-varying CVR factor. The results from simulation proved that CVR is an effective and economical tool for load conservation.
