Current Injection Based Quasi-Static Time Series Load Flow Algorithm for Distribution System with Multiple Distributed Energy Resources

In this paper, a current injection-based QSTS load flow approach has been developed to simulate and analyze the interactions between Distributed Energy Resources (DERs) and voltage-regulating devices over a given time. The novelty is that the paper proposes a comprehensive modeling approach that takes into account the intricacies of both voltage-regulating devices and DERs. By integrating these models into the QSTS simulation, the researchers can perform detailed analyses and simulations to evaluate the effects of DERs on control devices and assess the overall impact on the grid’s stability and operation. The process involves modeling the voltage-regulating devices, such as the load tap changers and voltage regulators, in a way that accurately represents their physical characteristics and control strategies. This enables the simulation to mimic the real-world behavior of these devices under various conditions. The time series analysis has been successfully validated using a state-of-the-art QSTS solver, demonstrating that the developed approach is both efficient and accurate.
