📢 [NEW ARTICLE] 📢 👉 Discover without further delay our latest article “How load banks contribute to electrical grid stability”. 👀 📰 "The energy transition towards renewable sources such as solar and wind, while essential for a sustainable future, poses significant challenges to the stability of electrical grids. The intermittent nature of these energy sources can cause substantial frequency variations, thus threatening the continuity and quality of electricity supply. In this context, load banks play a crucial role by simulating substantial electrical consumption and helping to stabilize the grid. What causes frequency variations? What is aFRR? How do load banks contribute to electrical grid stability?". 📰 --------- [...] To read more, follow the link in the comments!⬇️ #renewableenergy #loadbank #loadtesting #bancdecharge #energy #energiesrenouvelables

Renewable Energy can come from many sources. But wind and solar power are those that can be setup in more places in the world and allow access to lower cost, cleaner energy sources that we need in the decarbonization journey. The growth in these energy types in the last decade has been great. Its wonderful to see so many countries that get more than 25% of their grid energy from solar and wind. #renewableenergy #sdg7 #sustainability

Hydro, Wind & Solar power: Resources, Variability & Forecast" is a comprehensive study that explores the potential of renewable energy sources- hydroelectric, wind, and solar power. The study assesses the availability of these sources in specific regions, taking into account geographical, environmental, and infrastructural factors. It also examines the inherent fluctuations and intermittency of wind and solar power due to changing weather conditions and explores strategies to manage and optimize their unpredictable nature. The study also highlights the crucial need for accurate prediction methods to anticipate energy generation from these sources, supporting efficient grid management and enhancing grid reliability. By harnessing these clean energy sources while addressing their unique challenges, we can achieve a sustainable and reliable energy future.  #RenewableEnergy #Sustainability

Sadly, utility companies are taking advantage of this by charging different tariffs during the day with 5 PM to 12 AM being the highest and 9 AM to 3PM being the cheapest since no one is at home; kids are at schools and parents are working. #solarenergy #renewableenergy #utilities #tariff #electricity

Good illustration of duck curve to bring out the challenges ahead for meeting day & night energy demand .

Problem Statement: A typical solar power plant that may generate its full capacity in the afternoons. However, the power plant should limit its power export based on load demand. Due to government subsidies, solar power producing plants were profitable earlier in 2012. However, the scenario later altered, not due to a lack of government encouragement, but due to a dramatic shift in the load curve. Root-cause: The "duck curve" is a term commonly used in the context of grid-connected photovoltaic (PV) systems, particularly in the context of electricity generation from solar power. It refers to a graphical representation of the net electricity demand on the grid over the course of a day, considering the impact of solar energy generation. The name "duck curve" comes from the shape of the graph, which resembles a duck with its head and beak facing downward. The curve typically shows three key features: 1.    Morning Ramp (up to 6.00AM): In the early morning hours, before the sun rises or when the solar generation is low, the demand for electricity is relatively high. This is because people are waking up, turning on lights, appliances, and starting their daily activities. This is the "tail" of the duck. 2.    Morning between 6.00AM to 10.00AM or Morning Ramp-Down: As the sun rises, solar panels start to produce electricity, but since most people are not at home or businesses aren't fully operational yet, the demand for electricity is low. 3.    Mid-Day Trough: As the sun rises and solar PV generation increases, it starts to offset a significant portion of the electricity demand. During sunny hours, when solar generation is at its peak, the overall electricity demand on the grid decreases, leading to a "trough" in the curve. This causes a dip in the curve, forming the "belly" of the duck. 4.    Evening Ramp: Towards the evening, something interesting happens, as the sun sets and solar generation decreases, electricity demand rises again. People return home, turn on lights, appliances, and air conditioning, leading to an increase in electricity consumption. This forms the "neck" of the duck. 5.    Finally, in the late evening, the demand for electricity gradually decreases as people go to bed, forming the "head" of the duck.

Simplifying the #DuckCurve for the insightful post below - Imagine a typical day. As the sun rises, solar panels start to produce electricity, but since most people are not at home or businesses aren't fully operational yet, the demand for electricity is low. This is the "tail" of the duck. As the day progresses, the sun gets higher, and solar panels produce more and more electricity. But since many people are still at work or school, the demand isn't very high. This causes a dip in the curve, forming the "belly" of the duck. In the late afternoon and early evening, something interesting happens. The sun starts to set, and solar panels produce less electricity. But this is also the time when people come home from work or school and start to use more electricity by turning on lights, appliances, and electronics. This causes a sharp increase in demand, just when solar power is starting to decrease. This forms the "neck" of the duck. Finally, in the late evening, the demand for electricity gradually decreases as people go to bed, forming the "head" of the duck. The challenge here is that the peak demand for electricity (the neck of the duck) doesn't match up with the peak production of solar power (the belly of the duck). This mismatch can potentially lead to issues with the stability of the electricity grid, hence the concern about the "Duck Curve". #solarpower #renewableenergy

There is an article, published in POWER magazine which shows how the UK, USA and other western countries are falling far behind the push towards waste-to-energy (WTE) across Asia. The futility and environmental downsides of the blinkered focus on wind and solar are also exposed.    It also shows how WTE plants are being built worldwide, leaving their owners free and clear of any financial liability whatsoever.   https://lnkd.in/eKWVrPHr
