In order to solve the problem that voltage source converter based multi-terminal direct current (VSC-MTDC) system cannot provide inertia and participate in frequency modulation after connecting AC power grid under traditional control strategy, an adaptive strategy on virtual is proposed. First, relationship between DC was established by a control, allowing VSC-MTDC side. Second, address limited...

Two interconnected AC microgrids are proposed based on three renewable energy sources (RESs): wind, solar, and biogas. The wind turbine drives a permanent magnet synchronous generator (PMSG). A solar photovoltaic system (SPVS) with an appropriate inverter was incorporated. biogas genset (BG) consists of engine coupled generator. microgrids, M1 M2, were considered for study in this work. microgr...

Grid frequency support, e.g., by the virtual inertia control (VIC), of photovoltaic (PV) systems, is more demanded than ever before. To achieve full-range support (i.e., to tackle under- or overfrequency issues), power reserve necessary for PV systems. Accordingly, a (PRC) method based on maximum point tracking (MPPT) adopted in this article, referring as MPPT-PRC. It measures real-time availab...

Abstract: The use of wind power generation (WPG) as a source for black starts will significantly enhance the resiliency of power systems and shorten their recovery time from blackouts. Given that frequency stability is the most serious issue during the initial recovery period, virtual inertia control can enable wind turbines to provide frequency support to an external system. In this study, a g...

A unified control framework is proposed for the control of fluid powered human power amplifiers. Human power amplifiers are mechanical tools that humans operate directly and the human force is amplified hydraulically or pneumatically. The tool and the environment forces would therefore appear to the human as having been scaled down. Ideally, the assistive force is transparent to the human such ...

In many physical human-robot interaction scenarios, such as haptic virtual environments for training and rehabilitation, it is desirable to carefully control the apparent inertia of a robot. Inertia compensation can be used to mitigate forces felt by the user during free-space motion, and rendering of additional inertia is desired for particular rehabilitation and training procedures. Many fact...

This paper presents an advanced virtual inertia control strategy for wind farms to provide transient power support in the presence of frequency events, where a fuzzy active disturbance rejection controller is developed enable operation energy storage system (ESS) so as regulation grid. To effectively estimate under uncertain noises, rules are presented adaptively tune parameters extended state ...

Compared to conventional DC transmission, Voltage source converter based high voltage direct current transmission (VSC-HVDC) has the advantages of independently controllable power, no commutation failure, reactive power compensation and low harmonic levels. However, VSC-HVDC cannot provide effective frequency support regulation for system after grid connection. For this reason, an adaptive neur...

The virtual inertia technology of DGs (Distributed Generations) can provide and damping support for the power system by imitating traditional synchronous machine. However, inherent delay problems around communication process links control will make an impact on fast effect. In this paper, based hierarchical scheme considering distributed generations integration systems is proposed. architecture...
