…shows the second-by-second solar output at a typical-good day, with relatively little short-term volatility. The statistical distribution of different days’ solar volatility is plotted in candlestick charts and marimekko charts…
…power volatility events, where output fell by over 10% from its trailing ten-minute average level (example below). 40% of these volatility events lasted less than 10-seconds. 80% of the volatility…
…economically smooth them. Solar heavy grids may thus become prone to unbearable volatility? Our 17-page note outlines this important challenge, and finds that high-voltage interconnectors cure renewables volatility most effectively….
…and year-by-year volatility is 9% of the annual average. Solar insolation is volatile. It would be helpful for a stable grid to smooth each of these different time-periods of volatility….
This data-file contains the output from some enormous data-pulls, evaluating UK grid power generation by source, its volatility, and the relationship to hourly traded power prices. We conclude the grid…
…the power drops due to the sun setting. Then we aggregated all of the second-by-second volatility and power drops. The typical second-by-second volatility of solar power is surprisingly high, with…
UK wind power has almost trebled since 2016. But its output is volatile, now varying between 0-50% of the total grid. Hence this 14-page note assesses the volatility, using granular,…
…So will the high volatility persist? This is the question in today’s 6-page note. We attribute two-thirds of the volatility gains to gas shortages and high absolute power prices. However,…
