Virtual inertia is an effective control approach to attenuate sudden voltage changes during transient events in low-inertia dc grids. While methods have been proposed implement virtual inertia, its impact on grid stability the presence of constant power loads (CPLs) remains unclear. In this letter, we perform a rigorous analysis for grids with CPLs powered by virtual-inertia-enhanced converters...

This paper proposes a novel virtual inertia controller for converters in power systems, which can solve the system's nonlinearity frequency support. First, system dynamics are formulated as nonlinear state-space, reciprocal of is modeled control input. Correspondingly, cost function defined by considering deviation and rate change frequency, preserve tradeoff between critical limits respective ...

This article presents an enhanced control strategy for voltage source converters (VSCs) based on virtual inertia concept. Considering the significant share of renewable-based generations, frequency stability is noted as one most challenges modern low-inertia power systems. Therefore, first contribution this article, dynamic equations converter are utilized in order to study its proficient activ...

-In haptic devices the problem of major concern is the inertia offered by the haptic device. When using it in unconstrained space, it should offer the least inertia. Depending on the interaction mechanism we are required to adapt different control algorithms to maintain transparency. This paper investigates force feedback method of inertia reduction and analyses its advantages over the feed for...

In a DC microgrid (DC-MG), the dc bus voltage is vulnerable to power fluctuation derived from the intermittent distributed energy or local loads variation. In this paper, a virtual inertia control strategy for DC-MG through bidirectional grid-connected converters (BGCs) analogized with virtual synchronous machine (VSM) is proposed to enhance the inertia of the DC-MG, and to restrain the dc bus ...

This paper presents a data-driven virtual inertia control method for doubly fed induction generator (DFIG)-based wind turbine to provide support in the presence of frequency events. The Markov parameters system are first obtained by monitoring grid and operation state. Then, state observer is developed evaluate vector optimal controller. Furthermore, controller emulation through closed solution...
