Programmed PWM to improve power quality in systems with distributed generation units
Pulse-Width Modulated (PWM) inverters are widely applied in Distributed Generation (DG) units and power quality equipment owing to their excellent performance and flexible control means. Programmed PWM (PPWM), as a special type of optimal PWM strategy, theoretically allows for setting the fundamental and the selected harmonic amplitudes directly to arbitrary values. The algorithms for solving ...

What the heck is a smart grid anyway?
You know the old adage, ‘Never talk about politics or religion in polite company’? I’m beginning to think we need to add a third restraint, one against debate over the meaning of smart grid.Okay, it’s not exactly a dinnertime topic. But I’ve discovered in gatherings of energy nerds (I’m one), discussion can become fairly heated over what constitutes “smart grid.”On the one side are the ...

The electricity meter follows the new development trend of the EV charging station
Currently, pure electric vehicles can not completely replace gasoline vehicles. For users, the priority problem is battery sustainability. For premium and middle-end electric vehicles are able to 500km pure electric battery sustainability. Actually should take many factors into consideration, electric vehicles are able to 400km basically. This range is similar with traditional gasoline vehicles. ...

How some climate “wins” can lead to other uphill battles in the clean energy fight
Proponents should consider all possible reactions in order to create a smoother path forward for clean energy. As the adage goes, following every action is a reaction. As elsewhere, this is true in politics, where every move is followed by a series of countermeasures. Lately, climate and energy have increasingly been at the political fore. It follows then, that climate policy “wins,” ...

DSOs are the Gatekeepers of our Net-Zero Future: A Conversation with Eurelectric
80% of global CO2 emissions are due to the production and consumption of energy Climate change is primarily an energy challenge. Today 80% of global CO2 emissions are due to energy production and consumption. In 2019, power generation accounted for nearly 45% of those emissions, while demand-side emissions corresponded to 55% of the total. We can still limit global heating to 1.5°C, but ...

Distributed energy will play a key role in Renewable Energy Zones. Here’s how.
With the continued stream of announcements around the early closure of coal-fired power plants across Australia, Renewable Energy Zones (REZs) are a key way forward as coal makes its exit. To date, there are 41 potential REZs flagged for potential development, each undergoing different phases of planning and consultation. According to a recent EnergyCo event, New South Wales has less than ...
