Design and testing capabilities of low-inertia energy system-based frequency control using Typhoon HIL real-time digital simulator

Adoption of microgrids and related technologies is inevitable, keeping in view of the prosumer-rich modern power systems. With the introduction of a wide range of distributed energy resources on the distribution side, traditional unidirectional power flow is getting altered by bidirectional power flow in the network. With the bidirectional power flow in the network, system complexity is getting intensified to a new level. Additionally, with the introduction of intermittent source-powered distributed energy resources, operation, and maintenance challenges are at an all-time high. Traditional approaches to available tools may not be able to simulate all such newly evolving issues in the last hierarchy of power systems. Although some tools are available for this purpose, some face compatibility issues with the latest available software interface, and some require rigorous training to use them. On the contrary, Typhoon HIL's real-time digital simulator has no compatibility issue with the latest software interface, and the process is comparatively automated to expedite the test process. In this work, the author(s) expound Typhoon HIL real-time digital simulator applications in the context of active distribution network frequency analysis. Conjointly the author(s) also explored some of the very important facets aligned with active distribution network automation, communication, and different forms of real-time simulation.
