Abstract—AC Microgrids, in presence of highly non-linear loads, require a tighter regulation of line voltage to maintain power quality. This article proposes an outer virtual impedance loop to shape the
Surging energy demands and prices of buildings are turning leaders to efficiency retrofits to reduce energy costs and improve long-term energy security.
Dutch cyclists rode down the world''s first bike path made entirely of discarded plastic this week, in a move aimed at reducing the millions of tonnes wasted every year.
Amid an electricity crisis, many Nigerian small businesses run on petrol generators. This solar-microgrid start-up is working to connect them to clean energy.
In response to the constant power negative impedance characteristics on the load side of a ship DC microgrid, leading to voltage
Battery energy storage systems can address the challenge of intermittent renewable energy. But innovative financial models are needed to encourage deployment.
Normally, a fifth of global gas and oil trade passes through this chokepoint. That''s 20 million barrels of oil a day. But why are people talking so much about this one small waterway - and how
Pacific small island states, contributing only 0.03% of global emissions, are leading with ambitious renewable energy projects and net-zero goals by 2050.
Based on the developed impedance model, a stability criterion and a voltage oscillation evaluation method are proposed. Moreover, an impedance notch strategy is proposed for the energy
Renewables-based microgrids and peer-to-peer (P2P) energy trading can boost energy security as they are self-sufficient and run independent of large grids.
This paper presents a novel and resilient control strategy for isolated AC microgrids based on a Multiple Second-Order Generalized Integrator with Frequency-Locked Loop architecture and a
The reliability of new energy microgrid plays a very important role in the normal operation of power grid, so it is extremely urgent to improve the reliability of new energy microgrid. Aiming at
Microgrids can step in when the main electricity grid fails. And as they can be powered by renewables, they are a sustainable and affordable option, too.
The high proportion of nonlinear and unbalanced loads results in power quality issues in islanded microgrids. This paper presents a novel control strategy for harmonic and unbalanced power
Technological change, geoeconomic fragmentation, economic uncertainty, demographic shifts and the green transition – individually and in combination are among the major drivers
Local communities generating their own power could become 90% energy self-sufficient, with potential to be fully self-reliant in the future, according to a Dutch study.
Impedance model plays an important role in stability analysis of DC microgrids (MGs) with intuitiveness and effectiveness, especially when the state-space models with detailed system parameters are
To address this issue, we propose a feed-forward compensation control method based on impedance shaping. This involves designing a transfer function within the current feed-forward loop
In this article, a method is proposed to increase the accuracy of
