Weekly power simulation, week 16 of 2024 Yet another week with solar and wind powering future-Denmark 100% of the time. Last week saw sunny spring weather here in Denmark, with most trees now budding out, and Danes enjoying the nice (albeit still not too warm) outside. The energy system was dominated by daily solar spikes upwards of 15GW, on top of a relatively consistent 'base layer' of onshore and offshore wind. In total, 2.7 TWh renewable electricity fed into the grid, of which roughly half to cover regular demand, a third available for PtX - and 0.4TWh exported or curtailed. ----- Each week, I run a simulation using real-world generation data from the Danish power grid, with #windenergy and #solarenergy scaled to match future (2033) capacities, as forecasted by the Danish Energy Agency. See earlier posts by searching for #WeeklyPowerSimulation The original idea for such a simplified, but very illustrative, simulation is David Osmond's from Australian Windlab.

Fascinating article this morning in Renewable Energy World about the expected shift from today's standard grid following inverters in solar applications to grid forming inverters in the future (see link below in comments). As the generation mix on the grid shifts towards more inverter-based generation (solar, wind, storage), a new approach to maintaining voltage, frequency, and stability will be needed. More sophisticated inverters can fill the void. Energy storage systems, which already use grid forming inverters in microgrid applications, will be especially helpful in the grid of tomorrow. This kind of development is particularly interesting because it reinforces several key themes that have been influential in the energy transition: - The constant evolution of technology. - The complexities of managing the electric grid, which is both massive and increasingly critical to day-to-day life. - The key role that public policy plays; we often think about incentives and trade policy, but basic research and development may be the most important aspect role played by the public sector. One key question I have is whether a shift to grid-forming inverters will simplify power system studies and speed up the interconnection process? I'd love to hear thoughts from any power system planners and analytical studies experts. #solar #energytransition

Weekly power simulation, week 23 of 2024 Another beautiful week in the Danish energy system, with lots of wind and solar, making up 100% of power demand, plus enabling hydrogen and power-to-X to run at 91% capacity. Roughly 20% of renewable generation is 'excess' to be either exported, or curtailed. Power demand tends to be lower in the summer - at least, it is today, which is what this simulation is based on. Denmark consumes about 20-25% less power in June, compared to January (respectively 3.7GW and 4.7GW on average) ----- Each week, I run a simulation using real-world generation data from the Danish power grid, with #windenergy and #solarenergy scaled to match future (2033) capacities, as forecasted by the Danish Energy Agency.

Weekly power simulation, week 12 of 2024 Yet another case of wind, solar, storage, and flexibility interacting to ensure Danish power demand was matched 100% by wind and solar last week. And with the beautiful transition from wind-solar-wind on Wednesday, I think it justifies a 'feels good' meme. 97.5% renewable share year-to-date. ----- Each week, I run a simulation using real-world generation data from the Danish power grid, with #windenergy and #solarenergy scaled to match future (2033) capacities, as forecasted by the Danish Energy Agency.

As summer temperatures rise, the American electric grid faces a crucial test. An NERC report shows that new solar developments are helping keep the power on during peak demand. Solar power growth is making a significant impact, shifting areas from high-risk to stable positions. With forecasts projecting 10% of national electric generation coming from solar by summer's end, it's clear that renewable energy is shaping the future of our energy landscape. Let's work together to build a more resilient and sustainable energy future. #SolarPower #RenewableEnergy #GridReliability 🌞🔋🌿 https://lnkd.in/eZ9cFK7w #SolarPower #RenewableEnergy #GreenTech #SustainableLiving #EcoFriendlyInnovation

Weekly power simulation, week 11 of 2024 No such thing as perfect in the energy system - it's all trade offs and balances... HOWEVER, last week was pretty darn near perfect in our simulation. Wind and solar directly made up 97.2% of Danish power demand, but when adding storage and demand-side flexibility, Denmark was powered by 100% solar and wind last week! 97.2% renewable share year-to-date. ----- Each week, I run a simulation using real-world generation data from the Danish power grid, with #windenergy and #solarenergy scaled to match future (2033) capacities, as forecasted by the Danish Energy Agency.

Wind power and solar photovoltaics are variable energy sources, making it challenging to power electric cars with renewable energy. This #technicalarticle covers the renewable-based charging stations: https://lnkd.in/eytBBBcm #ChargingForFuture #EVCharging

EcoDataTrend is commencing a "Power Up Your Knowledge" series where critical concepts within the energy transition space would be explained in simple terms. This would be done on a weekly basis, exploring each concept in detail for better understanding. This week's #knowledgebite is "Grid Integration" 👉 Grid integration is the process of connecting and effectively incorporating renewable energy sources, like solar ☀ and wind 🌪 power, into the existing electricity grid ⚡ 👉 The grid must constantly balance the amount of electricity produced with the amount being used. Too much or too little electricity can cause problems like blackouts or equipment damage ☣ 👉 Effective grid integration involves using batteries to store excess energy produced during peak production times (e.g., sunny or windy days), releasing it during low production times 🔋 #powerupyourknowledge

As we head into President's Day weekend, this week CAISO sets another record! Few days ago, Battery Storage discharge peaks at 5,625MW during the afternoon discharge hours tackling the demand peak and effectively managing the solar duck curve. Very exciting to see renewable energy firming supported by large energy storage system. Grid Status provides an excellent view on how each of the ISOs are tackling grid challenges and provides an accurate view of LMPs facilitating / incentivizing needed stability response from the market. Lots of recent detailed dashboards available tracking frequency movements, solar + wind generation view (ERCOT), etc. Grid resiliency is the key to success for #gridmodernization. Very important for us to recognize the importance of the bigger picture and what problem we are solving. Remember, again, #bess is not a generation asset, it's a balancing solution providing multi-stacked stability support system. Much needed for our green energy future!
