More renewables mean less stable grids, researchers find

Grid stability is likely to be increasingly challenged as power distribution moves from a centralized to a more decentralized model, new research has found.

According to a paper published this week in the journal Nature Energy by researchers from Germany’s Max Planck Institute for Dynamics and Self-Organization and the UK’s Queen Mary University of London, integrating growing numbers of renewable power installations and microgrids onto the grid can result in larger-than-expected fluctuations in grid frequency.

The researchers collected data from grids of various sizes in Germany, France, the UK, Finland, Mallorca, Japan and the US. Based on this data, they developed mathematical models that “can establish the influence of making the grid smaller or of adding a bit more renewable energy” in order to aid in planning, said Professor Christian Beck of Queen Mary University, one of the paper’s co-authors.

The team found that small grids like Mallorca’s displayed larger frequency deviations than larger grids, such as continental Europe’s. And comparing different regions showed that a larger share of renewable generation resulted in larger frequency deviations.

“The grid operators want the frequency to be 50 Hz, but it fluctuates a little bit around this all the time,” said Beck. “We can now establish the probability that the deviation is more than 2 per cent or so, which is a big deviation, and we found that the probability of that is higher than expected from pure random fluctuation.”

Beck told PEi that the research team’s “first surprise was that energy trading had a significant impact on the grids studied” after Germany’s grid and others displayed particularly large fluctuations every 15 minutes, corresponding to spot market trading.

“The grid frequency had big jumps every 15-30 minutes,” he said, “and it wasn’t clear to us before that trading has such a big effect. Most people were worried about renewables because they are unpredictable and certainly produce fluctuations in frequency. Trading gives a similar order of, or stronger, fluctuation, which hadn’t been clear to us or, I think, to most people.”

Comparatively, the research showed that a larger share of renewable generation in a given region resulted in larger deviations from the standard 50 Hz. For example, the UK, with more renewables than the US, also had larger frequency deviations. To integrate more renewables onto the UK grid, the research team recommends increasing primary control and demand response.

“The UK is somewhat special,” Beck said, “in that it has a much higher component of wind power contributing, and it also has an overall smaller grid than the rest of Europe. Still, frequency fluctuations caused by trading seem to be at least as relevant as fluctuations caused by renewables.”

Asked about the effects on microgrids, he said that “the maths allows us to extrapolate the effects depending on the size of the grid. If we extrapolate our results to smaller grids, then indeed we would be implying that the effects are more pronounced there, and if people wish to have a microgrid then they need to relax a little bit the conditions they demand on constant frequency.”

“I don’t think we are saying anything against microgrids,” he added. “You just have to complement them with suitable control strategies to make sure the frequency is constant enough.”

The idea that by some miraculous yet to be invented ‘smart’ grid this problem can be overcome belongs to the domain of futuristic solutions. Obviously the more failure prone advanced electronics you add to the problem, the solution becomes a problem. 

And all this still is based on the current situation without having provisions for the enormous extra load Electric Vehicles will put on that grid.

If ever the general transport currently based on hydrocarbons where to be replaced by electric the current grid and further infrastructure would buckle at the first time the  47 quadrillion Btu in 2012 to 94 quadrillion Btu in 2040 for the transport sector alone would be trying to get that of any electric grid, being it smart or super-intelligent.

Defending the car industry because it is too stupid to defend itself.

Here’s what you need to know.

  1. Dieselgate was about higher than allowed NOx emissions caused by car manufacturers rigging their engines to cheat emissions tests.
  2. EPA imagines NOx as a precursor to fine particulate matter (PM2.5).
  3. It is claimed that PM2.5 causes millions of deaths every year.
  4. Scare Pollution debunks the claim that PM2.5 kills anyone. So NOx kills no one.
  5. So there is nothing to the extra NOx emissions and this study except a lot of junk science.

The media release is here

It must be said that none nowhere ever  managed to show a causal link between pm2.5 and health/longevity , at the very best one could show that in fact pm2.5 has no effect on health except when taken in extreme doses as in smoking (which counts for 20.000 times the pm2.5 per cigarette as compared to the outside air and even than it’s impossible to pinpoint if the smokers died from cancerous/toxic substances in that smoke rather than the particulate matter).

As of today nobody can show a death certificate which claims pm2.5 as cause of death but by setting the standards of air-pollution to the level of pm2.5 all air on the whole of earth can be deemed as being polluted as long as one keeps on setting the ‘safe’ level lower and lower.

So in fact in the western world there is no notable air-pollution if one just discounts the fairytale of particulate matter as a danger to public health.

It is however a perfect system to scare people to pay exorbitant prices for energy. The most ‘green’ countries have the highest consumer prices for energy which is great for the industry. Those benefit most since all subsidies for ‘green’ energy makes for a gorgeous business model. Money for free. No wonder many jump on the bandwagon

Evidently Nuclear is still the least lethal form of energy production and has the advantage of stifling the CO2 hysteria by being almost emission free

US Would Crumble Under European-Style Energy Policies

US Would Crumble Under European-Style Energy Policies

Europe crumbled already, look at its dismal state of the economy

 

The European energy policies would impose a $676 billion drag on the U.S. economy, the report states, and result in Americans paying an extra $4,800 per year to heat their homes.

The price increase would ultimately lead to the loss of several million U.S. jobs, according to the report, which is part of a series of studies conducted by the group leading up to the presidential election. The group compared U.S. and European energy prices between 2008 and 2014.

“The types of policies being advocated by leading candidates, such as restricting energy production and imposing new mandates, would drive up energy prices and reduce America’s global competitiveness,” said Karen Harbert, president and CEO of the U.S. Chamber’s Institute for 21st Century Energy.

European restrictions on low-cost, existing electricity supply and oil and natural gas supplies, as well as a cascade of subsidies propping up the solar and wind power industries, contribute to the problem in European states, according to Harbert’s group.

The German government, for instance, shovels more than $1.1 trillion into the wind power industry, despite the fact that wind turbines have not actually reduced carbon emissions enough to slow global warming.

Carbon taxes, subsidies, and restrictive policies, the report states, have made Europe almost completely dependent on other countries for 70 percent of its natural gas and 88 percent of its crude oil; whereas the U.S. receives only about 4 percent and 27 percent of gas and oil from foreign countries, respectively.

Energy expenditures would more than double from $583 billion to $1,220 billion under the EU price scenario. This $610 billion increase in costs would directly reduce the amount of money each household has available to spend on goods and services.

California to vastly augment electricity costs

California to vastly augment electricity costs

In order to comply with millennial desire to replace reality with an alternative reality California subsidizes far out visionary Elon Musk: 

In what is being considered a major win (loss) to those in the field of next-level of energy technologyTesla was awarded a contract to provide thousands of energy storage units to Southern California.

The Southern California Edison energy company contracted out Tesla last week to provide 20-megawatts of energy storage equipment to their power grid. The equipment will be used to stop blackouts should the grid’s main fossil-fuel based energy sources fail. The Tesla Powerpack energy storage units will be installed at a SCE substation in Mira Loma and must be up and running by the end of December.

The amount of equipment being installed is enough to keep 2,500 homes with power for a day, or enoughto charge 1,000 Tesla cars, the company claimed in a blog post.

The cost of the complete energy storage system isn’t clear. As noted by Bloomberg, a 2-megawatt Tesla energy storage system runs around $2.9 million, and contracts that involve more energy than that are negotiated on a per-situation basis.

In late 2015, the Aliso Canyon natural gas reservoir ruptured, causing a major spill of methane gas and forcing over 8,000 local residents out of their homes. Following this incident, the California government has been attempting to expand its energy-storage storage efforts to prevent any potential loss of power during times of high electricity usage.

Last month, California officials green-lighted two other grid energy-storage contracts that would account for 37-megawatts of storage.

This project is one of the most notable happenings on the energy side of Tesla since the company set out to buy SolarCity in August.
