The absence of the phase-locked loop (PLL) in grid-forming GFM inverters due to its instability issues brings a problem of lack of a detecting unit for GFM control. This paper studies the DC bus controller for grid fluctuation detection and control. The control is done using a DC bus controller which calculates the required power reference for the GFM primary and secondary control. The virtual synchronous generation algorithm is used for primary and secondary frequency control and grid synchronization. The simulation results show a power compensation tracking and frequency Nadir gain of 0.2Hz and a 0.15Hz frequency compensation compared with the GFM without the controller. Grid frequency stability has also been increased using the proposed controller.

This paper provides an overview of various control strategies for DC–DC converters along with a brief discussion on various performance indices for evaluating the reliability of designed controller. DC–DC converters are emerging as the fastest‐growing interfacing devices in the world because of their emergent applications in almost all domains of engineering. Notably, the non‐linear behavior of DC–DC converters offers a perplexing problem in designing a robust controller. A robust controller must ensure proper closed‐loop stability with desired performance and reliable control for output voltage regulation in the event of various possible perturbations. This creates the requirement for practically implementable non‐linear controllers that can effectively overlook the drawbacks of linear controllers. The prominence of this composition is based on the expansion in tuning techniques of proportional‐integral‐derivative controller gain parameters using linear strategies and heading towards non‐linear strategies by reviewing 196 research papers. The modification in non‐linear control strategies in terms of their fundamental features associated with key benefits and limitations are comprehensively reviewed. This study mostly revolves around non‐linear internal model control (IMC) strategies for parameter tuning of IMC‐based controllers for various order of plants with an improved degree of freedom.
