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 ...

Cascade failures and distributed generation in power grids
Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

When Disaster Response Drives Transformational Change to Grids, Fuel Cells are the Preferred Choice of Many Energy Prosumers
The increasing frequency of weather-related disasters puts emergency disaster response in the headlines often and encourages more and more systematic solutions. In the example of wildfires in the U.S., where 30,000 fires burned over 3.5 million acres between January – August 2019, systematic solutions are crucial. Seeking to minimize fire damage, utilities in California have instilled the ...

Should energy managers worry about energy data security?
Ah, 2016 – the year of fake news, celebrity deaths and cyber attacks, namely to the electricity grids of several countries. The biggest story came out of the United States, where the Washington Post (falsely) reported that a Vermont utility had been infiltrated by Russian hackers. Should energy managers be concerned about cyber attacks like these? Embracing connectivity thanks to the IoT ...

New horizons for sludge
Increasing production worldwide, higher cost for disposal, tighter restriction sludge management solutions are in high demand. New technologies are rapidly multiplying, fueled as well by sludge’s potential as a source of energy and potential for phosphorus recycling. Several drivers are contributing to the need for sludge solutions. A global population of 7.5 billion ...

Power Outages, Extreme Weather, & Microgrids Explained
Recent wildfires in California and bomb cyclones in New England have led to massive power outages. Here are 10 answers to frequently asked questions about why outages occur, how power lines start wildfires, and alternatives to our aging and unreliable power grid. How do power grids work? Utilities generate electricity at power plants, and then distribute it to our homes and businesses over ...
